What is (are) Prostate Cancer ?

Surgery is a common treatment for early stage prostate cancer. It is used to remove the cancer. The surgeon may remove the entire prostate -- a type of surgery called radical prostatectomy -- or, in some cases, remove only part of it. Sometimes the surgeon will also remove nearby lymph nodes. Side effects may include lack of sexual function (impotence), or problems holding urine (incontinence).

What are the treatments for Prostate Cancer ?

Radiation therapy uses high-energy x-rays to kill cancer cells and shrink tumors. Doctors may recommend it instead of surgery or after surgery to destroy any cancer cells that may remain in the area. In advanced stages, the doctor may recommend it to relieve pain or other symptoms. Radiation can cause problems with impotence and bowel function. The radiation may come from a machine, which is external radiation, or from tiny radioactive seeds placed inside or near the tumor, which is internal radiation. Men who receive only the radioactive seeds usually have small tumors. Some men receive both kinds of radiation therapy. For external radiation therapy, patients go to the hospital or clinic -- usually 5 days a week for several weeks. Internal radiation may require patients to stay in the hospital for a short time.

What are the treatments for Prostate Cancer ?

Hormonal therapy deprives cancer cells of the male hormones they need to grow and survive. This treatment is often used for prostate cancer that has spread to other parts of the body. Sometimes doctors use hormonal therapy to try to keep the cancer from coming back after surgery or radiation treatment. Side effects can include impotence, hot flashes, loss of sexual desire, and thinning of bones.

What are the treatments for Prostate Cancer ?

Regardless of the type of treatment you receive, you will be closely monitored to see how well the treatment is working. Monitoring may include - a PSA blood test, usually every 3 months to 1 year. - bone scan and/or CT scan to see if the cancer has spread. a PSA blood test, usually every 3 months to 1 year. bone scan and/or CT scan to see if the cancer has spread. - a complete blood count to monitor for signs and symptoms of anemia. - looking for signs or symptoms that the disease might be progressing, such as fatigue, increased pain, or decreased bowel and bladder function. a complete blood count to monitor for signs and symptoms of anemia. looking for signs or symptoms that the disease might be progressing, such as fatigue, increased pain, or decreased bowel and bladder function.

What are the treatments for Prostate Cancer ?

Through research, doctors are trying to find new, more effective ways to treat prostate cancer. Cryosurgery -- destroying cancer by freezing it -- is under study as an alternative to surgery and radiation therapy. To avoid damaging healthy tissue, the doctor places an instrument known as a cryoprobe in direct contact with the tumor to freeze it. Doctors are studying new ways of using radiation therapy and hormonal therapy, too. Studies have shown that hormonal therapy given after radiation therapy can help certain men whose cancer has spread to nearby tissues. Scientists are also testing the effectiveness of chemotherapy and biological therapy for men whose cancer does not respond or stops responding to hormonal therapy. They are also exploring new ways to schedule and combine various treatments. For example, they are studying hormonal therapy to find out if using it to shrink the tumor before a man has surgery or radiation might be a useful approach. They are also testing combinations of hormone therapy and vaccines to prevent recurrence of prostate cancer. In 2010, the FDA approved a therapeutic cancer vaccine, Provenge, for use in some men with metastatic prostate cancer. This approval was based on the results of a clinical trial that demonstrated a more than 4-month improvement in overall survival compared with a placebo vaccine. Other similar vaccine therapies are in development.

Who is at risk for Prostate Cancer? ?

Researchers are studying changes in genes that may increase the risk for developing prostate cancer. Some studies are looking at the genes of men who were diagnosed with prostate cancer at a relatively young age, less than 55 years old, and the genes of families who have several members with the disease. Other studies are trying to identify which genes, or arrangements of genes, are most likely to lead to prostate cancer. Much more work is needed, however, before scientists can say exactly how genetic changes relate to prostate cancer. At the moment, no genetic risk has been firmly established.

What is (are) COPD ?

Chronic obstructive pulmonary disease, or COPD, is a progressive lung disease in which the airways of the lungs become damaged, making it hard to breathe. You may also have heard COPD called other names, like emphysema or chronic bronchitis. In people who have COPD, the airways that carry air in and out of the lungs are partially blocked, making it difficult to get air in and out. COPD is a major cause of death and illness throughout the world. It kills more than 120,000 Americans each year. That's one death every 4 minutes. How COPD Affects Airways The "airways" are the tubes that carry air in and out of the lungs through the nose and mouth. The airways of the lungs branch out like an upside-down tree. At the end of each branch are many small, balloon-like air sacs. In healthy people, the airways and air sacs are elastic (stretchy). When you breathe in, each air sac fills up with air, like a small balloon, and when you breathe out, the balloon deflates and the air goes out. In people with COPD, the airways and air sacs lose their shape and become floppy. Less air gets in and less air goes out of the airways because - The airways and air sacs lose their elasticity like an old rubber band. - The walls between many of the air sacs are destroyed. - The walls of the airways become thick and inflamed or swollen. - Cells in the airways make more mucus or sputum than usual, which tends to clog the airways. The airways and air sacs lose their elasticity like an old rubber band. The walls between many of the air sacs are destroyed. The walls of the airways become thick and inflamed or swollen. Cells in the airways make more mucus or sputum than usual, which tends to clog the airways. COPD Develops Slowly, Has No Cure When COPD is severe, shortness of breath and other symptoms of COPD can get in the way of even the most basic tasks, such as doing light housework, taking a walk, even washing and dressing. COPD develops slowly, and it may be many years before you notice symptoms like feeling short of breath. Most of the time, COPD is diagnosed in middle-aged or older people. There is no cure for COPD. The damage to your airways and lungs cannot be reversed, but there are things you can do to control the disabling effects of the disease. COPD is not contagious. You cannot catch it from someone else.

What causes COPD ?

Smoking Most cases of COPD develop over time, from breathing in fumes and other things that irritate the lungs. Some of the things that put you at risk for COPD include smoking, environmental exposure, and genetic factors. Cigarette smoking is the most common cause of COPD in the United States (either current or former smokers). Pipe, cigar, and other types of tobacco smoking can also cause COPD, especially if the smoke is inhaled. Environmental Exposure COPD can also occur in people who have had long-term exposure to things that can irritate your lungs, like chemical fumes, or dust from the environment or workplace. Heavy or long-term exposure to secondhand smoke or other air pollutants may also contribute to COPD even if you have never smoked or had long-term exposure to harmful pollutants. Secondhand smoke is smoke in the air from other people smoking. Genetic Factors In a small number of people, COPD is caused by a genetic condition known as alpha-1 antitrypsin, or AAT, deficiency. People who have this condition have low levels of alpha-1 antitrypsin (AAT)a protein made in the liver. Having a low level of the AAT protein can lead to lung damage and COPD if you're exposed to smoke or other lung irritants. If you have this condition and smoke, COPD can worsen very quickly. While very few people know if they have AAT deficiency, it is estimated that about 1 in every 1,600 people to about 1 in every 5,000 people have it. People with AAT deficiency can get COPD even if they have never smoked or had long-term exposure to harmful pollutants. Asthma Although uncommon, some people who have asthma can develop COPD. Asthma is a chronic (long-term) lung disease that inflames and narrows the airways. Treatment usually can reverse the inflammation and narrowing. However, if not, COPD can develop.

How to prevent COPD ?

If you have COPD, you can take these steps to prevent complications and control the disabling effects of the disease. - Quit smoking. - Avoid exposure to pollutants and lung irritants. - Take precautions against the flu. - Talk to your doctor about the flu and pneumonia vaccines. - See your doctor on a regular basis. - Follow your treatments for COPD exactly as your doctor prescribes. Quit smoking. Avoid exposure to pollutants and lung irritants. Take precautions against the flu. Talk to your doctor about the flu and pneumonia vaccines. See your doctor on a regular basis. Follow your treatments for COPD exactly as your doctor prescribes. Quit Smoking If you smoke, the most important thing you can do to prevent more lung damage is to stop smoking. Quitting can help prevent complications and slow the progress of the disease. It is also important to stay away from people who smoke and places where you know there will be smokers. To help you quit, there are many online resources and several new aids available from your doctor or health care provider. The National Cancer Institute (NCI) has information on smoking cessation. Visit SmokeFree.gov , or check out NCI's Clear Horizons, a quit smoking guide for people 50+. You can also visit The American Lung Association, or call 1-800-QUIT NOW (1-800-784-8669). Avoid Exposure to Pollutants and Lung Irritants Try to stay away from other things that could irritate your lungs, like dust and strong fumes. Stay indoors when the outside air quality is poor. You should also stay away from places where there might be cigarette smoke. Take Precautions Against the Flu The flu (influenza) can cause serious problems for people who have COPD. Do your best to avoid crowds during flu season. In addition to avoiding people with the flu, remembering to wash and sanitize your hands can be one of the best ways to guard against getting sick. Talk to Your Doctor About the Flu (influenza) and Pneumonia Vaccines Talk with your doctor about getting a yearly flu shot and whether and when you should get the pneumonia vaccine. Flu shots can reduce your risk of getting the flu, and the pneumonia vaccine lowers your risk for pneumococcal pneumonia (NU-mo-KOK-al nu-MO-ne-ah) and its complications. Both of these illnesses are major health risks for people who have COPD. See Your Doctor Regularly See your doctor or health care provider regularly even if you are feeling fine. Make a list of your breathing symptoms and think about any activities that you can no longer do because of shortness of breath. Be sure to bring a list of all the medicines you are taking to each office visit. Follow Your Treatments Follow your treatments for COPD exactly as your doctor prescribes. They can help you breathe easier, stay more active, and avoid or manage severe symptoms.

What are the symptoms of COPD ?

Common Symptoms The most common symptoms of COPD are - a cough that does not go away - coughing up lots of sputum (mucus). a cough that does not go away coughing up lots of sputum (mucus). These symptoms often start years before the flow of air in and out of the lungs is reduced. Not everyone who has a cough and sputum goes on to develop COPD. Other common symptoms of COPD include - shortness of breath while doing activities you used to be able to do - wheezing (a whistling sound when you breathe) - tightness in the chest. shortness of breath while doing activities you used to be able to do wheezing (a whistling sound when you breathe) tightness in the chest. Getting a Diagnosis Your doctor will diagnose COPD based on your signs and symptoms, your medical and family histories, and test results. If your doctor thinks you may have COPD, he or she will examine you, listen to your lungs, and ask you questions about your medical history, and what lung irritants you may have been around for long periods of time. The Spirometry Test To confirm a diagnosis of COPD, your doctor will use a breathing test called spirometry. The test is easy and painless and shows how much air you can breathe out and measures how fast you can breathe it out. In a spirometry test, you breathe hard into a large hose connected to a machine called a spirometer. When you breathe out, the spirometer measures how much air your lungs can hold and how fast you can blow air out of your lungs. Spirometry can detect COPD before symptoms develop. Your doctor also might use the test results to find out how severe your COPD is and to help set your treatment goals. The test results also may help find out whether another condition, such as asthma or heart failure, is causing your symptoms. Determining COPD Severity Based on this test, your doctor can determine if you have COPD and how severe it is. There are four levels of severity for COPD: - people at risk for COPD - people with mild COPD - people with moderate COPD - people with severe COPD. people at risk for COPD people with mild COPD people with moderate COPD people with severe COPD. People at risk for developing COPD have a normal breathing test and mild symptoms such as chronic cough and sputum (mucus) production. People with mild COPD have mild breathing limitation. Symptoms may include a chronic cough and sputum (mucus) production. At this stage, you may not be aware that airflow in your lungs is reduced. People with moderate COPD have a breathing test that shows worsening airflow blockages. Symptoms may be worse than with mild COPD and you may experience shortness of breath while working hard, walking fast, or doing brisk activity. At this stage, you would seek medical attention. People with severe COPD have a breathing test that shows severe limitation of the airflow. People with severe COPD will be short of breath after just a little activity. In very severe COPD, complications like respiratory failure or signs of heart failure may develop. At this stage, quality of life is impaired and worsening symptoms may be life-threatening. Other Tests Other tests are used to rule out other causes of the symptoms. - Bronchodilator reversibility testing uses the spirometer and medications called bronchodilators to assess whether breathing problems may be caused by asthma. Bronchodilator reversibility testing uses the spirometer and medications called bronchodilators to assess whether breathing problems may be caused by asthma. - A chest X-ray or a chest CT scan may also be ordered by your doctor. These tests create pictures of the structures inside your chest, such as your heart, lungs, and blood vessels. The pictures can show signs of COPD. They also may show whether another condition, such as heart failure, is causing your symptoms. A chest X-ray or a chest CT scan may also be ordered by your doctor. These tests create pictures of the structures inside your chest, such as your heart, lungs, and blood vessels. The pictures can show signs of COPD. They also may show whether another condition, such as heart failure, is causing your symptoms. - An arterial blood gas test is another test that is used. This blood test shows the oxygen level in the blood to see how severe your COPD is and whether you need oxygen therapy. An arterial blood gas test is another test that is used. This blood test shows the oxygen level in the blood to see how severe your COPD is and whether you need oxygen therapy.

What is (are) COPD ?

Chronic obstructive pulmonary disease, or COPD, is a progressive lung disease in which the airways of the lungs become damaged, making it harder to breathe. With COPD, airways become blocked, making it harder to get air in and out.

What causes COPD ?

COPD is a disease that slowly worsens over time, especially if you continue to smoke. If you have COPD, you are more likely to have lung infections, which can be fatal. If the lungs are severely damaged, the heart may be affected. A person with COPD dies when the lungs and heart are unable to function and get oxygen to the body's organs and tissues, or when a complication, such as a severe infection, occurs. Treatment for COPD may help prevent complications, prolong life, and improve a person's quality of life.

What causes COPD ?

Cigarette smoking is the most common cause of COPD. Most people with COPD are smokers or have been smokers in the past. Breathing in other fumes and dusts over long periods of time can also lead to COPD. Pipe, cigar, and other types of tobacco smoking can cause COPD, especially if the smoke is inhaled. Exposure to secondhand smoke can play a role in causing COPD. Most people with COPD are at least 40 years old or around middle age when symptoms start.

What are the symptoms of COPD ?

The most common symptoms of COPD are a cough that does not go away and coughing up a lot of sputum (mucus). These symptoms may occur years before lung damage has reduced the flow of air in and out of the lungs. Other symptoms of COPD include shortness of breath, especially with exercise; wheezing (a whistling sound when you breathe); and tightness in the chest.

How to diagnose COPD ?

To confirm a COPD diagnosis, a doctor will use a breathing test called spirometry. The test is easy and painless. It shows how well the lungs are working. The spirometer measures how much air the lungs can hold and how fast air is blown out of the lungs. Other tests, such as bronchodilator reversibility testing, a chest X-ray, and arterial blood gas test, may be ordered.

What are the treatments for COPD ?

Treatment for COPD can be different for each person and is based on whether symptoms are mild, moderate or severe. Treatments include medication, pulmonary or lung rehabilitation, oxygen treatment, and surgery. There are also treatments to manage complications or a sudden onset of symptoms.

How to diagnose COPD ?

If you have not been exercising regularly, you should get the advice of your doctor before starting. The symptoms of COPD are different for each person. People with mild COPD may not have much difficulty walking or exercising. As the symptoms of COPD get worse over time, a person may have more difficulty with walking and exercising. You should talk to your doctor about exercising and whether you would benefit from a pulmonary or lung rehabilitation program.

How to prevent COPD ?

If you smoke, the most important thing you can do to prevent more lung damage is to stop smoking. It is also important to stay away from people who smoke and places where you know there will be smokers. Avoid exposure to pollutants like dust, fumes, and poor air quality, and take precautions to prevent flu and pneumonia. Following your doctor's instructions with medications and rehabilitative treatment can help alleviate COPD symptoms and control the disabling effects of the disease.

What are the treatments for COPD ?

Bronchodilators and inhaled steroids are two medications used to treat COPD. Bronchodilators work by relaxing the muscles around the airways, opening them and making it easier to breathe. People with mild COPD take bronchodilators using an inhaler only when needed. Those with moderate or severe COPD may need more regular treatment. Inhaled steroids also are used for people with moderate or severe COPD in order to reduce swelling in the airways.

What are the symptoms of COPD ?

Call your doctor right away if your symptoms worsen suddenly. People with COPD may have symptoms that suddenly get worse. When this happens, you have a much harder time catching your breath. Symptoms that worsen suddenly can include sudden chest tightness, more coughing, a change in your sputum (mucus), or fever. Your doctor will look at things that may be causing these sudden symptoms. Sometimes the symptoms are caused by a lung infection.

What is (are) Paget's Disease of Bone ?

Enlarged and Misshapen Bones Paget's disease of bone causes affected bones to become enlarged and misshapen. Our bones are living tissue, and our bodies are constantly breaking down old bone and replacing it with new bone. In Paget's disease, however, old bone is broken down and replaced at a faster rate than normal. The new bone is larger and weaker than normal bone. Paget's disease can occur in any bone in the body, but it is most common in the pelvis, spine, skull, and leg bones. It may occur in just one bone or in several bones, but it does not affect the entire skeleton or spread from affected bones to normal bones. Common symptoms include pain, misshapen bones, and a greater chance of broken bones. Complications Paget's disease can also lead to complications, such as arthritis, headaches, hearing loss, or nervous system problems, depending on which bones are affected. If not treated, Paget's disease can reduce a person's ability to perform activities of daily living, thereby reducing quality of life. Although it is the second most common bone disease after osteoporosis, Paget's disease is still uncommon. According to Bone Health and Osteoporosis: A Report of the Surgeon General, an estimated 1 million people in the U.S. have Paget's disease, or about 1.3 people per 100 men and women age 45-74. The disease is more common in older people and those of Northern European heritage. Men are more likely than women to have the disease. Cause is Unknown Paget's disease is named after the British surgeon, Sir James Paget, who first identified the disease in 1877. Researchers are not sure what causes it. Heredity may be a factor in some cases. Research suggests that a close relative of someone with Paget's disease is seven times more likely to develop the disease than someone without an affected relative. However, most people with Paget's disease do not have any relatives with the disease. Researchers think the disease also may be caused by other factors, such as a slow-acting virus. A Treatable Disease The good news is that Paget's disease of bone is treatable, especially if it is diagnosed early. In recent years, the Food and Drug Administration has approved several medications that can stop or slow the disease's progression. In some cases, surgery can help patients manage the symptoms and complications of the disease.

What are the symptoms of Paget's Disease of Bone ?

Symptoms Many people don't know they have Paget's disease because they have a mild case of the disease and do not have any symptoms. However, people with more advanced cases of the disease will likely have symptoms. Symptoms vary depending on which bone or bones are affected. People with Paget's disease may experience - bone pain - misshapen bones - fractures - osteoarthritis of the joints adjacent to bone affected by the disease. bone pain misshapen bones fractures osteoarthritis of the joints adjacent to bone affected by the disease. Paget's disease can also cause a variety of neurological complications as a result of compression of nerve tissue by bone affected by the disease. Misshapen bone is most obvious when the leg bones, skull, or bones of the spine are affected. Leg bones may become bowed, the skull may become enlarged, and malformed spinal bones may cause curvature of the spine. Complications People with Paget's disease also are more likely to break bones because bones affected by the disease are more fragile. Enlarged and malformed bones can distort the position of bones and joints. This causes wear and tear on the joints next to bones affected by Paget's disease, resulting in arthritis. On very rare occasions, Paget's disease is linked to the development of osteosarcoma, a type of bone cancer. Less than one percent of patients have this complication.

How to diagnose Paget's Disease of Bone ?

An Underdiagnosed Disease Experts believe that Paget's disease is underdiagnosed; people with a mild case and no symptoms may never know they have the disease. Or, they may receive a diagnosis by accident when x-rays or other laboratory tests done for another reason reveal Paget's disease. When symptoms do occur, they usually appear gradually and, in the early stages, may be confused with those of arthritis or other medical problems. Sometimes a person may not receive a clear diagnosis until the disease progresses and complications develop. Diagnostic Tests X-rays are almost always used to diagnose Paget's disease, but the disease may be discovered using one of three tests: - x-rays - an alkaline phosphatase blood test - or a bone scan. x-rays an alkaline phosphatase blood test or a bone scan. Bones affected by Paget's disease have a distinctive appearance on x-rays, which may show increased bone density, an abnormal bone structure, bowing, and enlargement. X-rays of leg bones may show very tiny fractures called microfractures. The enzyme alkaline phosphatase is involved in the normal growth of new bone. Having higher-than-normal levels of this chemical in the blood, however, may be a sign of Paget's disease. The alkaline phosphatase blood test measures the level of this substance. A bone scan provides a picture of the affected bones that doctors can use to see how far the disease has progressed. If a bone scan done for another reason suggests Paget's disease, the doctor can order x-rays to confirm the diagnosis. If the Disease Runs in the Family Early diagnosis and treatment of Paget's disease is important. Because Paget's disease can be hereditary, some experts recommend that the brothers, sisters, and children of anyone with the disease talk to their doctor about having an alkaline phosphatase blood test every 2 to 3 years after about age 40.

What are the treatments for Paget's Disease of Bone ?

Early Diagnosis is Important Although there is no cure for Paget's disease of bone, it is treatable. Treatment is most effective when the disease is diagnosed early, before it causes major changes in the affected bones. The goal of treatment is to relieve bone pain and prevent the disease from progressing. Medications Are Available The Food and Drug Administration has approved several medications that can stop or slow down the progression of the disease and reduce pain and other symptoms. These medications fall into two categories: bisphosphonates and calcitonin. Both medications work by stopping or reducing the excessive breakdown of old bone that leads to excessive formation of new, but weaker, bone. People with Paget's disease should talk to their doctors about which medication is right for them. Bisphosphonates Six bisphosphonates are currently available for patients with Paget's disease. Doctors most commonly recommend the strongest ones, which include - risedronate - alendronate - pamidronate - zoledronic acid - tiludronate and etidronate are not as strong but may be appropriate for some patients. risedronate alendronate pamidronate zoledronic acid tiludronate and etidronate are not as strong but may be appropriate for some patients. Some of the bisphosphonates approved for the treatment of Paget's disease, including risedronate and alendronate, are also approved for the treatment of osteoporosis. However, people with Paget's disease must take higher dosages of these medicines for shorter periods of time than people with osteoporosis. Calcitonin Doctors also may prescribe calcitonin to treat Paget's disease in some people, although it has been found to be less effective than bisphosphonates. Calcitonin is a naturally occurring hormone made by the thyroid gland. Your doctor may recommend that you repeat calcitonin treatments with brief rest periods in between treatments. The nasal spray form of calcitonin is not recommended or approved to treat Paget's disease. Surgery Surgery may be a treatment option for some people. Hip or knee replacement surgery may help people with severe arthritis. Surgery can also realign affected leg bones to reduce pain or help broken bones heal in a better position. Nutrition and Exercise Good nutrition and exercise are important for bone health, and that is true for people with Paget's disease as well. Women over age 50 should consume 1,200 milligrams (mg) of calcium daily. Men between the ages of 51 and 70 should consume 1,000 mg of calcium a day, and men over 70 should consume 1,200 mg per day. People ages 51 to 70 should consume at least 600 international units (IU) of vitamin D daily. People over age 70 should consume at least 800 IUs daily. Calcium keeps bones strong, and vitamin D helps the body absorb calcium. Exercise is very important in maintaining bone health, avoiding weight gain, and keeping joints mobile. However, people with Paget's disease need to avoid putting too much stress on affected bones. They should discuss their exercise program with their doctor to make sure it is a good one for them. Finding New Treatments Recently, there have been major advances in the treatment of Paget's disease of bone. Research into new treatments continues. Some researchers are trying to identify the genetic and viral causes of the disease. Other researchers are learning more about bone biology to better understand how the body breaks down old bone and replaces it with new bone.

What is (are) Paget's Disease of Bone ?

Paget's disease of bone is a disease that causes affected bones to become enlarged and misshapen. Our bones are living tissue, and our bodies are constantly breaking down old bone and replacing it with new bone. In Paget's disease, however, old bone is broken down and replaced at a faster rate than normal. The new bone is larger and weaker than normal bone.

What are the symptoms of Paget's Disease of Bone ?

Pain may be a symptom, especially among people with more advanced Paget's disease. Affected bones also can become enlarged, misshapen, and more fragile and likely to break. Misshapen bones tend to be most noticeable in the legs, skull, and spine.

What are the complications of Paget's Disease of Bone ?

Over time, Paget's disease may lead to other medical conditions, including arthritis, headaches, hearing loss, and nervous system problems, depending on which bones are affected. On very rare occasions, Paget's disease is associated with the development of osteosarcoma, a type of bone cancer. Less than one percent of patients have this complication.

How to diagnose Paget's Disease of Bone ?

Paget's disease is almost always diagnosed by x-ray, although it may be discovered using one of two other tests: an alkaline phosphatase blood test or a bone scan. Paget's disease is often found by accident when a person undergoes one of these tests for another reason. In other cases, a person experiences problems that lead his or her physician to order these tests. If Paget's disease is first suggested by an alkaline phosphatase blood test or bone scan, the physician usually orders an x-ray to verify the diagnosis. A bone scan is typically used to identify all the bones in the skeleton that are affected by the disease.

What are the treatments for Paget's Disease of Bone ?

The Food and Drug Administration has approved several medications that can stop or slow down the progression of the disease and reduce pain and other symptoms. These medications fall into two categories: bisphosphonates and calcitonin. Doctors most often prescribe one of the four strongest bisphosphonates, which are risedronate, alendronate, pamidronate, and zoledronic acid.

What are the treatments for Paget's Disease of Bone ?

Yes. Some complications from Paget's disease respond well to surgery. Joint replacement may be helpful in people with severe arthritis of the hip or knee. Surgery can also realign affected leg bones to reduce pain or help broken bones heal in a better position.

What is (are) Stroke ?

Stroke -- A Serious Event A stroke is serious, just like a heart attack. Each year in the United States, approximately 795,000 people have a stroke. About 610,000 of these are first or new strokes. On average, one American dies from stroke every four minutes. Stroke is the fourth leading cause of death in the United States, and causes more serious long-term disabilities than any other disease. Nearly three-quarters of all strokes occur in people over the age of 65. And the risk of having a stroke more than doubles each decade between the ages of 55 and 85. Stroke occurs in all age groups, in both sexes, and in all races in every country. It can even occur before birth, when the fetus is still in the womb. Learning about stroke can help you act in time to save a relative, neighbor, or friend. And making changes in your lifestyle can help you prevent stroke. What Is Stroke? A stroke is sometimes called a "brain attack." Most often, stroke occurs when blood flow to the brain stops because it is blocked by a clot. When this happens, the brain cells in the immediate area begin to die. Some brain cells die because they stop getting the oxygen and nutrients they need to function. Other brain cells die because they are damaged by sudden bleeding into or around the brain. The brain cells that don't die immediately remain at risk for death. These cells can linger in a compromised or weakened state for several hours. With timely treatment, these cells can be saved. New treatments are available that greatly reduce the damage caused by a stroke. But you need to arrive at the hospital as soon as possible after symptoms start to prevent disability and to greatly improve your chances for recovery. Knowing stroke symptoms, calling 911 immediately, and getting to a hospital as quickly as possible are critical. Ischemic Stroke There are two kinds of stroke. The most common kind of stroke is called ischemic stroke. It accounts for approximately 80 percent of all strokes. An ischemic stroke is caused by a blood clot that blocks or plugs a blood vessel supplying blood to the brain. Blockages that cause ischemic strokes stem from three conditions: - the formation of a clot within a blood vessel of the brain or neck, called thrombosis - the movement of a clot from another part of the body, such as from the heart to the neck or brain, called an embolism - a severe narrowing of an artery (stenosis) in or leading to the brain, due to fatty deposits lining the blood vessel walls. the formation of a clot within a blood vessel of the brain or neck, called thrombosis the movement of a clot from another part of the body, such as from the heart to the neck or brain, called an embolism a severe narrowing of an artery (stenosis) in or leading to the brain, due to fatty deposits lining the blood vessel walls. Hemorrhagic Stroke The other kind of stroke is called hemorrhagic stroke. A hemorrhagic stroke is caused by a blood vessel that breaks and bleeds into the brain. One common cause of a hemorrhagic stroke is a bleeding aneurysm. An aneurysm is a weak or thin spot on an artery wall. Over time, these weak spots stretch or balloon out due to high blood pressure. The thin walls of these ballooning aneurysms can rupture and spill blood into the space surrounding brain cells. Artery walls can also break open because they become encrusted, or covered with fatty deposits called plaque, eventually lose their elasticity and become brittle, thin, and prone to cracking. Hypertension, or high blood pressure, increases the risk that a brittle artery wall will give way and release blood into the surrounding brain tissue.

What are the symptoms of Stroke ?

Know the Signs Knowing the warning signs of stroke and controlling stroke's risk factors can lower your risk of death or disability. If you suffer a stroke, you may not realize it at first. The people around you might not know it, either. Your family, friends, or neighbors may think you are unaware or confused. You may not be able to call 911 on your own. That's why everyone should know the signs of stroke and know how to act fast. Warning signs are clues your body sends to tell you that your brain is not receiving enough oxygen. If you observe one or more of the following signs of a stroke or "brain attack," don't wait. Call 911 right away! Common Signs of Stroke These are warning signs of a stroke: - sudden numbness or weakness of the face, arm, or leg, especially on one side of the body - sudden confusion, trouble speaking or understanding - sudden trouble seeing in one or both eyes - sudden trouble walking, dizziness, loss of balance or coordination - sudden severe headache with no known cause. sudden numbness or weakness of the face, arm, or leg, especially on one side of the body sudden confusion, trouble speaking or understanding sudden trouble seeing in one or both eyes sudden trouble walking, dizziness, loss of balance or coordination sudden severe headache with no known cause. Other danger signs that may occur include double vision, drowsiness, and nausea or vomiting. Don't Ignore "Mini-Strokes" Sometimes the warning signs of stroke may last only a few moments and then disappear. These brief episodes, known as transient ischemic attacks or TIAs, are sometimes called "mini-strokes." Although brief, TIAs identify an underlying serious condition that isn't going away without medical help. Unfortunately, since they clear up, many people ignore them. Don't ignore them. Heeding them can save your life. Why It's Important To Act Fast Stroke is a medical emergency. Every minute counts when someone is having a stroke. The longer blood flow is cut off to the brain, the greater the damage. Immediate treatment can save peoples lives and enhance their chances for successful recovery. Ischemic strokes, the most common type of strokes, can be treated with a drug called t-PA that dissolves blood clots obstructing blood flow to the brain. The window of opportunity to start treating stroke patients is three hours, but to be evaluated and receive treatment, patients need to get to the hospital within 60 minutes. What Should You Do? Don't wait for the symptoms of stroke to improve or worsen. If you believe you are having a stroke, call 911 immediately. Making the decision to call for medical help can make the difference in avoiding a lifelong disability and in greatly improving your chances for recovery. If you observe someone having a stroke if he or she suddenly loses the ability to speak, or move an arm or leg on one side, or experiences facial paralysis on one side call 911 immediately.

Who is at risk for Stroke? ?

A risk factor is a condition or behavior that increases your chances of getting a disease. Having a risk factor for stroke doesn't mean you'll have a stroke. On the other hand, not having a risk factor doesn't mean you'll avoid a stroke. But your risk of stroke grows as the number and severity of risk factors increase. These risk factors for stroke cannot be changed by medical treatment or lifestyle changes. - Age. Although stroke risk increases with age, stroke can occur at any age. Recent studies have found that stroke rates among people under 55 grew from 13 percent in 1993-1994, to 19 percent in 2005. Experts speculate the increase may be due to a rise in risk factors such as diabetes, obesity, and high cholesterol. Age. Although stroke risk increases with age, stroke can occur at any age.

Gender. Men have a higher risk for stroke, but more women die from stroke. - Race. People from certain ethnic groups have a higher risk of stroke. For African Americans, stroke is more common and more deadly even in young and middle-aged adults than for any ethnic or other racial group in the U.S. Studies show that the age-adjusted incidence of stroke is about twice as high in African Americans and Hispanic Americans as in Caucasians. An important risk factor for African Americans is sickle cell disease, which can cause a narrowing of arteries and disrupt blood flow. Race.

An important risk factor for African Americans is sickle cell disease, which can cause a narrowing of arteries and disrupt blood flow. - Family history of stroke. Stroke seems to run in some families. Several factors may contribute to familial stroke. Members of a family might have a genetic tendency for stroke risk factors, such as an inherited predisposition for high blood pressure (hypertension) or diabetes. The influence of a common lifestyle among family members could also contribute to familial stroke. Family history of stroke. Stroke seems to run in some families. Several factors may contribute to familial stroke. Members of a family might have a genetic tendency for stroke risk factors, such as an inherited predisposition for high blood pressure (hypertension) or diabetes. The influence of a common lifestyle among family members could also contribute to familial stroke. Some of the most important risk factors for stroke that CAN be treated are - high blood pressure - smoking - heart disease - high blood cholesterol - warning signs or history of a stroke - diabetes. high blood pressure smoking heart disease high blood cholesterol warning signs or history of a stroke diabetes. High Blood Pressure High blood pressure, also called hypertension, is by far the most potent risk factor for stroke. If your blood pressure is high, you and your doctor need to work out an individual strategy to bring it down to the normal range. Here are some ways to reduce blood pressure: - Maintain proper weight. - Avoid drugs known to raise blood pressure. - Cut down on salt. - Eat fruits and vegetables to increase potassium in your diet. - Exercise more. Maintain proper weight. Avoid drugs known to raise blood pressure. Cut down on salt. Eat fruits and vegetables to increase potassium in your diet. Exercise more. Your doctor may prescribe medicines that help lower blood pressure. Controlling blood pressure will also help you avoid heart disease, diabetes, and kidney failure. Smoking Cigarette smoking has been linked to the buildup of fatty substances in the carotid artery, the main neck artery supplying blood to the brain. Blockage of this artery is the leading cause of stroke in Americans. Also, nicotine raises blood pressure, carbon monoxide reduces the amount of oxygen your blood can carry to the brain, and cigarette smoke makes your blood thicker and more likely to clot. Your doctor can recommend programs and medications that may help you quit smoking. By quitting -- at any age -- you also reduce your risk of lung disease, heart disease, and a number of cancers including lung cancer. Heart Disease Heart disease, including common heart disorders such as coronary artery disease, valve defects, irregular heart beat, and enlargement of one of the heart's chambers, can result in blood clots that may break loose and block vessels in or leading to the brain. The most common blood vessel disease, caused by the buildup of fatty deposits in the arteries, is called atherosclerosis, also known as hardening of the arteries. Your doctor will treat your heart disease and may also prescribe medication, such as aspirin, to help prevent the formation of clots. Your doctor may recommend surgery to clean out a clogged neck artery if you match a particular risk profile. High Blood Cholesterol A high level of total cholesterol in the blood is a major risk factor for heart disease, which raises your risk of stroke. Your doctor may recommend changes in your diet or medicines to lower your cholesterol. Warning Signs or History of Stroke Experiencing warning signs and having a history of stroke are also risk factors for stroke. Transient ischemic attacks, or TIAs, are brief episodes of stroke warning signs that may last only a few moments and then go away. If you experience a TIA, get help at once. Call 911. If you have had a stroke in the past, it's important to reduce your risk of a second stroke. Your brain helps you recover from a stroke by drawing on body systems that now do double duty. That means a second stroke can be twice as bad. Diabetes Having diabetes is another risk factor for stroke. You may think this disorder affects only the body's ability to use sugar, or glucose. But it also causes destructive changes in the blood vessels throughout the body, including the brain. Also, if blood glucose levels are high at the time of a stroke, then brain damage is usually more severe and extensive than when blood glucose is well-controlled. Treating diabetes can delay the onset of complications that increase the risk of stroke.

How to prevent Stroke ?

Stroke is preventable and treatable. A better understanding of the causes of stroke has helped people make lifestyle changes that have cut the stroke death rate nearly in half in the last two decades. Preventing Stroke While family history of stroke plays a role in your risk, there are many risk factors you can control: - If you have high blood pressure, work with your doctor to get it under control. - If you smoke, quit. - If you have diabetes, learn how to manage it. Many people do not realize they have diabetes, which is a major risk factor for heart disease and stroke. - If you are overweight, start maintaining a healthy diet and exercising regularly. - If you have high cholesterol, work with your doctor to lower it.

Diagnosing Stroke Physicians have several diagnostic techniques and imaging tools to help diagnose stroke quickly and accurately. The first step in diagnosis is a short neurological examination, or an evaluation of the nervous system. When a possible stroke patient arrives at a hospital, a health care professional, usually a doctor or nurse, will ask the patient or a companion what happened and when the symptoms began. Blood tests, an electrocardiogram, and a brain scan such as computed tomography or CT, or magnetic resonance imaging or MRI, will often be done. Measuring Stroke Severity One test that helps doctors judge the severity of a stroke is the standardized NIH Stroke Scale, developed by the National Institute of Neurological Disorders and Stroke at the National Institutes of Health, or NIH. Health care professionals use the NIH Stroke Scale to measure a patient's neurological deficits by asking the patient to answer questions and to perform several physical and mental tests. Other scales include the Glasgow Coma Scale, the Hunt and Hess Scale, the Modified Rankin Scale, and the Barthel Index. Diagnostic Imaging: CT Scan Health care professionals also use a variety of imaging techniques to evaluate acute stroke patients. The most widely used is computed tomography or CT scan, sometimes pronounced CAT scan, which is comprised of a series of cross-sectional images of the head and brain. CT scans are sensitive for detecting hemorrhage and are therefore useful for differentiating hemorrhagic stroke, caused by bleeding in the brain, from ischemic stroke, caused by a blockage of blood flow to the brain. Hemorrhage is the primary reason for avoiding thrombolytic therapy (drugs that break up or dissolve blood clots), the only proven therapy for acute ischemic stroke. Because thrombolytic therapy might make a hemorrhagic stroke worse, doctors must confirm that the acute symptoms are not due to hemorrhage prior to giving the drug. A CT scan may show evidence of early ischemia an area of tissue that is dead or dying due to a loss of blood supply. Ischemic strokes generally show up on a CT scan about six to eight hours after the start of stroke symptoms. Though not as common in practice, CT scans also can be performed with a contrast agent to help visualize a blockage in the large arteries supplying the brain, or detect areas of decreased blood flow to the brain. Because CT is readily available at all hours at most major hospitals, produces images quickly, and is good for ruling out hemorrhage prior to starting thrombolytic therapy, CT is the most widely used diagnostic imaging technique for acute stroke. Diagnostic Imaging: MRI Scan Another imaging technique used in acute stroke patients is the magnetic resonance imaging or MRI scan. MRI uses magnetic fields to detect a variety of changes in the brain and blood vessels caused by a stroke. One effect of ischemic stroke is the slowing of water movement through the injured brain tissue. Because MRI can show this type of injury very soon after stroke symptoms start, MRI has proven useful for diagnosing acute ischemic stroke before it is visible on CT. MRI also allows doctors to visualize blockages in the arteries, identify sites of prior stroke, and create a stroke treatment and prevention plan. Differences Between CT and MRI Scans MRI and CT are equally accurate for determining when hemorrhage is present. The benefit of MRI over a CT scan is more accurate and earlier diagnosis of ischemic stroke, especially for smaller strokes and transient ischemic attacks (TIAs). MRI can be more sensitive than CT for detecting other types of neurological disorders that mimic the symptoms of stroke. However, MRI cannot be performed in patients with certain types of metallic or electronic implants, such as pacemakers for the heart. Although increasingly used in the emergency diagnosis of stroke, MRI is not immediately available at all hours in most hospitals, where CT is used for acute stroke diagnosis. MRI typically takes longer to perform than CT, and therefore may not be the first choice when minutes count.

what research (or clinical trials) is being done for Stroke ?

The National Institute of Neurological Disorders and Stroke sponsors a wide range of basic and clinical research aimed at finding better ways to prevent, diagnose, and treat stroke, and to restore functions lost as a result of stroke. Preventing Secondary Brain Damage Currently, scientists are studying the risk factors for stroke and the process of brain damage that results from stroke. Some brain damage may be secondary, occurring after the initial death of brain cells caused by the lack of blood flow to the brain tissue. This secondary brain damage results from a toxic reaction to the primary damage. Researchers are studying this toxic reaction and ways to prevent secondary injury to the brain. Scientists hope to develop neuroprotective agents, or drugs that protect the brain, to prevent this damage. Animal Studies Scientists are also conducting stroke studies in animals. By studying stroke in animals, researchers hope to get a better picture of what might be happening in human stroke patients. Scientists can also use animal models to test promising therapies for stroke. If a therapy proves helpful for animals, scientists can consider testing the therapy in humans. One promising area of animal research involves hibernation. The dramatic decrease of blood flow to the brain in hibernating animals is so extensive that it would kill a non-hibernating animal. If scientists can discover how animals hibernate without experiencing brain damage, they may discover ways to stop the brain damage associated with decreased blood flow in stroke patients. Another study used a vaccine that interferes with inflammation inside blood vessels to reduce the frequency and severity of strokes in animals with high blood pressure and a genetic predisposition to stroke. Researchers hope that the vaccine will work in humans and could be used to prevent many of the strokes that occur each year in people with high risk factors. Can the Brain Repair Itself? Scientists also are working to develop new and better ways to help the brain repair itself to restore important functions to stroke patients. New advances in imaging and rehabilitation have shown that the brain can compensate for functions lost as a result of stroke. When cells in an area of the brain responsible for a particular function die after a stroke, the patient becomes unable to perform that function. However, the brain's ability to learn and change, called plasticity, and its ability to rewire the connections between its nerve cells means that it can compensate for lost functions. One part of the brain can actually change functions and take up the more important functions of a disabled part. Clinical Trials Clinical trials are scientific studies using volunteers that give researchers a way to test medical advances in humans. Clinical trials test surgical devices and procedures, medications, and rehabilitation therapies. They also test methods to improve lifestyles and mental and social skills. Clinical trials may compare a new medical approach to a standard one that is already available or to a placebo that contains no active ingredients or to no intervention. Some clinical trials compare interventions that are already available to each other. When a new product or approach is being studied, it is not usually known whether it will be helpful, harmful, or no different than available alternatives (including no intervention). The investigators try to determine the safety and usefulness of the intervention by measuring certain outcomes in the participants. Scientists are using clinical trials to - develop new and more effective treatments for stroke - discover ways to restore blood flow to the brain after stroke - improve recovery after stroke - learn more about the risk factors for stroke. develop new and more effective treatments for stroke discover ways to restore blood flow to the brain after stroke improve recovery after stroke learn more about the risk factors for stroke.

What is (are) Stroke ?

Some brain cells die because they stop getting the oxygen and nutrients they need to function. Other brain cells die because they are damaged by sudden bleeding into or around the brain. The brain cells that don't die immediately remain at risk for death. These cells can linger in a compromised or weakened state for several hours. With timely treatment these cells can be saved. Knowing stroke symptoms, calling 911 immediately, and getting to a hospital as quickly as possible are critical.

Who is at risk for Stroke? ?

Stroke occurs in all age groups, in both sexes, and in all races in every country. It can even occur before birth, when the fetus is still in the womb. Studies show the risk of stroke doubles for each decade between the ages of 55 and 85. However, a recent study found that stroke rates are on the rise for people under 55.

What is (are) Stroke ?

There are two kinds of stroke. The most common kind of stroke is called ischemic stroke. It accounts for approximately 80 percent of all strokes. An ischemic stroke is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind of stroke is called hemorrhagic stroke. A hemorrhagic stroke is caused by a blood vessel that breaks and bleeds into the brain.

What are the symptoms of Stroke ?

Warning signs are clues your body sends to tell you that your brain is not receiving enough oxygen. These are warning signs of a stroke, or brain attack: - sudden numbness or weakness of the face, arm, or leg, especially on one side of the body - sudden confusion, trouble speaking or understanding - sudden trouble seeing in one or both eyes - sudden trouble walking, dizziness, loss of balance or coordination - sudden severe headache with no known cause. sudden numbness or weakness of the face, arm, or leg, especially on one side of the body sudden confusion, trouble speaking or understanding sudden trouble seeing in one or both eyes sudden trouble walking, dizziness, loss of balance or coordination sudden severe headache with no known cause.

A risk factor is a condition or behavior that increases your chances of getting a disease. Having a risk factor for stroke doesn't mean you'll have a stroke. On the other hand, not having a risk factor doesn't mean you'll avoid a stroke. But your risk of stroke grows as the number and severity of risk factors increase. Risk factors for stroke include ones that you cannot control and ones that you can control. Some of the risk factors that you cannot control include - Age. Although stroke can occur at any age, the risk of stroke doubles for each decade between the ages of 55 and 85. - Gender. Men have a higher risk for stroke, but more women die from stroke. Men generally do not live as long as women, so men are usually younger when they have their strokes and therefore have a higher rate of survival. - Race. The risk of stroke is higher among African-American and Hispanic Americans. - Family History. Family history of stroke increases your risk. Age.

What are the treatments for Stroke ?

With stroke, treatment depends on the stage of the disease. There are three treatment stages for stroke: prevention, therapy immediately after stroke, and rehabilitation after stroke. Stroke treatments include medications, surgery, and rehabilitation.

What are the treatments for Stroke ?

Medication or drug therapy is the most common treatment for stroke. The most popular kinds of drugs to prevent or treat stroke are antithrombotics -- which include antiplatelet agents and anticoagulants -- and thrombolytics. Antithrombotics prevent the formation of blood clots that can become stuck in an artery of the brain and cause strokes. - In the case of stroke, doctors prescribe antiplatelet drugs mainly for prevention. The most widely known and used antiplatelet drug is aspirin. Other antiplatelet drugs include clopidogrel, ticlopidine, and dipyridamole. In the case of stroke, doctors prescribe antiplatelet drugs mainly for prevention. The most widely known and used antiplatelet drug is aspirin. Other antiplatelet drugs include clopidogrel, ticlopidine, and dipyridamole. - Anticoagulants reduce the risk of stroke by reducing the clotting property of the blood. The most commonly used oral anticoagulants include warfarin, also known as Coumadin, dabigatran (Pradaxa) and rivaroxaban (Xarelto). Injectable anticoagulants include heparin, enoxaparin (Lovenox), and dalteparin (Fragmin). Anticoagulants reduce the risk of stroke by reducing the clotting property of the blood. The most commonly used oral anticoagulants include warfarin, also known as Coumadin, dabigatran (Pradaxa) and rivaroxaban (Xarelto). Injectable anticoagulants include heparin, enoxaparin (Lovenox), and dalteparin (Fragmin). Thrombolytic drugs halt the stroke by dissolving the blood clot that is blocking blood flow to the brain. Ischemic strokes -- the most common kind -- can be treated with thrombolytic drugs. But a person needs to be at the hospital as soon as possible after symptoms start to be evaluated and receive treatment. A thrombolytic drug known as t-PA can be effective if a person receives it intravenously (in a vein) within 3 hours after his or her stroke symptoms have started. Because there is such a narrow time window for giving t-PA, it is important to note the time any stroke symptoms appear. Since thrombolytic drugs can increase bleeding, t-PA should be used only after the doctor is certain that the patient has suffered an ischemic and not a hemorrhagic stroke. Neuroprotectants are medications or other treatments that protect the brain from secondary injury caused by stroke. Although the FDA (Food and Drug Administration) has not approved any neuroprotectants for use in stroke at this time, many have been tested or are being tested in clinical trials. Cooling of the brain (hypothermia) is beneficial for improving neurological function after a cardiac arrest.

What are the treatments for Stroke ?

Surgery Surgery can be used to prevent stroke, to treat stroke, or to repair damage to the blood vessels or malformations in and around the brain. - Carotid endarterectomy is a surgical procedure in which a surgeon removes fatty deposits, or plaque, from the inside of one of the carotid arteries. The procedure is performed to prevent stroke. The carotid arteries are located in the neck and are the main suppliers of blood to the brain.

The carotid arteries are located in the neck and are the main suppliers of blood to the brain. Vascular Interventions In addition to surgery, a variety of techniques have been developed to allow certain vascular problems to be treated from inside the artery using specialized catheters with the goal of improving blood flow. (Vascular is a word that refers to blood vessels, arteries, and veins that carry blood throughout the body.) A catheter is a very thin, flexible tube that can be inserted into one of the major arteries of the leg or arm and then directed through the blood vessels to the diseased artery. Physicians trained in this technique called angiography undergo additional training to treat problems in the arteries of the brain or spinal cord. These physicians are called neurointerventionalists. - Angioplasty is widely used by angiographers to open blocked heart arteries, and is also used to prevent stroke. Angioplasty is a procedure in which a special catheter is inserted into the narrowed artery and then a balloon at the tip of the catheter is inflated to open the blocked artery. The procedure improves blood flow to the brain. Angioplasty is widely used by angiographers to open blocked heart arteries, and is also used to prevent stroke. Angioplasty is a procedure in which a special catheter is inserted into the narrowed artery and then a balloon at the tip of the catheter is inflated to open the blocked artery. The procedure improves blood flow to the brain. - Stenting is another procedure used to prevent stroke. In this procedure an angiographer inserts a catheter into the artery in the groin and then positions the tip of the catheter inside the narrowed artery. A stent is a tube-like device made of a mesh-like material that can be slipped into position over the catheter. When positioned inside the narrowed segment the stent is expanded to widen the artery and the catheter is removed. Angioplasty or stenting of the carotid artery can cause pieces of the diseased plaque to loosen. An umbrella-like device is often temporarily expanded above to prevent these pieces from traveling to the brain. Stenting is another procedure used to prevent stroke.

One device involves threading a catheter through the artery to the site of the blockage and then vacuuming out the clot. Another corkscrew-like device can be extended from the tip of a catheter and used to grab the clot and pull it out. Drugs can also be injected through the catheter directly into the clot to help dissolve the clot.

Brain plasticity is the brain's ability to learn and change, allowing it to adapt to deficits and injury and to take over the functions of damaged cells. When cells in an area of the brain responsible for a particular function die after a stroke, the patient becomes unable to perform that function. However, the brain's ability torewire the connections between its nerve cells allows it to compensate for lost functions.

What is (are) Diabetic Retinopathy ?

Can Cause Vision Loss, Blindness Diabetic retinopathy is a complication of diabetes and a leading cause of blindness. It occurs when diabetes damages the tiny blood vessels inside the retina in the back of the eye. A healthy retina is necessary for good vision. If you have diabetic retinopathy, at first you may notice no changes to your vision. But over time, diabetic retinopathy can get worse and cause vision loss. Diabetic retinopathy usually affects both eyes. Four Stages The four stages of diabetic retinopathy are - mild nonproliferative retinopathy - moderate nonproliferative retinopathy - severe nonproliferative retinopathy - proliferative retinopathy. mild nonproliferative retinopathy moderate nonproliferative retinopathy severe nonproliferative retinopathy proliferative retinopathy. The first stage is mild nonproliferative retinopathy. At this earliest stage, there are small areas of balloon-like swelling in the retina's tiny blood vessels. The second stage is moderate nonproliferative retinopathy. As the disease progresses, some blood vessels that nourish the retina are blocked. The third stage is severe nonproliferative retinopathy. Many more blood vessels are blocked, depriving several areas of the retina of their blood supply. These areas send signals to the body to grow new blood vessels for nourishment. The fourth stage is proliferative retinopathy. At this advanced stage, the signals sent by the retina for nourishment cause the growth of new blood vessels. These new blood vessels are abnormal and fragile. The new blood vessels grow along the retina and along the surface of the clear, vitreous gel that fills the inside of the eye. By themselves, these blood vessels do not cause symptoms or vision loss. However, they have thin, fragile walls. If they leak blood, severe vision loss and even blindness can result. Other Diabetic Eye Diseases In addition to diabetic retinopathy, other diabetic eye diseases that people with diabetes may face are cataract and glaucoma. See this graphic for a quick overview of diabetic eye disease, including how many people it affects, whos at risk, what to do if you have it, and how to learn more.

What causes Diabetic Retinopathy ?

Who Is at Risk? All people with diabetes -- both type 1 and type 2 -- are at risk for diabetic retinopathy. People with diabetes are also at increased risk for cataract and glaucoma. That's why everyone with diabetes should get a comprehensive dilated eye exam at least once a year. Between 40 to 45 percent of Americans diagnosed with diabetes have some stage of diabetic retinopathy. If you have diabetic retinopathy, your doctor can recommend treatment to help prevent its progression. How Vision Loss Occurs Blood vessels damaged from diabetic retinopathy can cause vision loss in two ways. Fragile, abnormal blood vessels can develop and leak blood into the center of the eye, blurring vision. This is proliferative retinopathy and is the fourth and most advanced stage of the disease. Fluid can leak into the center of the macula, the part of the eye where sharp, straight-ahead vision occurs. The fluid makes the macula swell, blurring vision. This condition is called macular edema. Macular edema can occur at any stage of diabetic retinopathy, although it is more likely to occur as the disease progresses. About half of the people with proliferative retinopathy also have macular edema. Macular edema can occur at any stage of diabetic retinopathy, although it is more likely to occur as the disease progresses. About half of the people with proliferative retinopathy also have macular edema. Have Dilated Eye Exams The National Eye Institute (NEI) urges everyone with diabetes to have a comprehensive dilated eye exam at least once a year. If you have diabetic retinopathy, you may need an eye exam more often. People with proliferative retinopathy can reduce their risk of blindness by 95 percent with timely treatment and appropriate follow-up care. Watch an animation to see what a comprehensive dilated eye exam includes.

What are the symptoms of Diabetic Retinopathy ?

Diabetic retinopathy often has no early warning signs. Don't wait for symptoms. Be sure to have a comprehensive dilated eye exam at least once a year to detect the disease before it causes damage to your vision. Vision Changes May Indicate Bleeding In the early stages of diabetic retinopathy, you may not notice any changes in your vision. But if diabetic retinopathy reaches its final stage, proliferative retinopathy, bleeding can occur. If this happens, at first, you will see a few specks of blood, or spots, floating in your vision. If spots occur, see your eye care professional as soon as possible. Early Treatment is Important You may need treatment before more serious bleeding or hemorrhages occur causing vision loss or possibly blindness. Hemorrhages tend to happen more than once, often during sleep. See how to find an eye care professional. Here is a list of questions to ask your eye care professional. Sometimes the spots clear without treatment, and you will see better. However, bleeding can reoccur and cause severely blurred vision. You need to be examined by your eye care professional at the first sign of blurred vision, before more bleeding occurs. If left untreated, proliferative retinopathy can cause severe vision loss and even blindness. Also, the earlier you receive treatment, the more likely treatment will be successful. Detection Diabetic retinopathy and macular edema are detected during a comprehensive eye exam that includes a visual acuity test, dilated eye exam, and tonometry. A visual acuity test is an eye chart test that measures how well you see at various distances. During the dilated eye exam, your eye care professional checks your retina for early signs of the disease, including - leaking blood vessels - retinal swelling such as macular edema - pale, fatty deposits on the retina -- signs of leaking blood vessels - damaged nerve tissue leaking blood vessels retinal swelling such as macular edema pale, fatty deposits on the retina -- signs of leaking blood vessels damaged nerve tissue Watch an animation showing what a comprehensive dilated eye exam involves. With tonometry, an instrument measures the pressure inside the eye. Numbing drops may be applied to your eye for this test. If your eye care professional believes you need treatment for macular edema, he or she may suggest a fluorescein angiogram. In this test, a special dye is injected into your arm. Pictures are taken as the dye passes through the blood vessels in your retina. The test allows your eye care professional to identify any leaking blood vessels and recommend treatment.

What are the treatments for Diabetic Retinopathy ?

Preventing Disease Progression During the first three stages of diabetic retinopathy, no treatment is needed, unless you have macular edema. To prevent progression of diabetic retinopathy, people with diabetes should control their levels of blood sugar, blood pressure, and blood cholesterol. Treatment for Macular Edema Research found that that prompt treatment of macular edema with anti-VEGF drugs, with or without laser treatment, resulted in better vision than laser treatment alone or steroid injections. When injected into the eye, these drugs reduce fluid leakage and interfere with the growth of new blood vessels in the retina. In some cases, focal laser treatment is used along with the eye injections. Your doctor places up to several hundred small laser burns in the areas of the retina around the macula that are leaking. These burns slow the leakage of fluid and reduce the amount of fluid in the retina. The surgery is usually completed in one session. Further treatment may be needed. Treatment for Diabetic Retinopathy Proliferative retinopathy is treated with laser surgery. This procedure is called scatter laser treatment. Scatter laser treatment helps to shrink the abnormal blood vessels. Your doctor places 1,000 to 2,000 laser burns in the areas of the retina away from the macula, causing the abnormal blood vessels to shrink. Because a high number of laser burns are necessary, two or more sessions usually are required to complete treatment. Although you may notice some loss of your side vision, scatter laser treatment can save the rest of your sight. Scatter laser treatment may slightly reduce your color vision and night vision. Scatter laser treatment works better before the fragile, new blood vessels have started to bleed. That is why it is important to have regular, comprehensive dilated eye exams. Even if bleeding has started, scatter laser treatment may still be possible, depending on the amount of bleeding. Learn more about laser treatment. Vitrectomy If the bleeding is severe, you may need a surgical procedure called a vitrectomy. During a vitrectomy, blood is removed from the center of your eye. Scatter laser treatment and vitrectomy are effective in treating proliferative retinopathy and in reducing vision loss. Once you have proliferative retinopathy, you always will be at risk for new bleeding. You may need treatment more than once to protect your sight. Learn more about a vitrectomy. Have Dilated Eye Exams The National Eye Institute (NEI) urges everyone with diabetes to have a comprehensive dilated eye exam at least once a year.

People with proliferative retinopathy can reduce their risk of blindness by 95 percent with timely treatment and appropriate follow-up care. Watch an animation to see what a comprehensive dilated eye exam includes. Research The National Eye Institute, or NEI, is conducting and supporting research that seeks better ways to detect, treat, and prevent vision loss in people with diabetes. This research is conducted through studies in the laboratory and with patients. For example, researchers are studying drugs for the treatment of proliferative retinopathy that may reduce the need for laser surgery. A major study has shown that better control of blood sugar levels slows the onset and progression of retinopathy. The people with diabetes who kept their blood sugar levels as close to normal as possible also had much less kidney and nerve disease. Better control also reduces the need for sight-saving laser surgery.

Both focal and scatter laser treatment are performed in your doctor's office or eye clinic. Before the surgery, your doctor will dilate your pupil and apply drops to numb the eye. The area behind your eye also may be numbed to prevent discomfort. The lights in the office will be dim. As you sit facing the laser machine, your doctor will hold a special lens to your eye. During the procedure, you may see flashes of light. These flashes eventually may create a stinging sensation that can be uncomfortable. You will need someone to drive you home after surgery. Because your pupil will remain dilated for a few hours, you should bring a pair of sunglasses. For the rest of the day, your vision will probably be a little blurry. If your eye hurts, your doctor can suggest treatment.

If you have a lot of blood in the center of the eye, or vitreous gel, you may need a vitrectomy to restore your sight. If you need vitrectomies in both eyes, they are usually done several weeks apart. A vitrectomy is performed under either local or general anesthesia. Your doctor makes a tiny incision in your eye. Next, a small instrument is used to remove the vitreous gel that is clouded with blood. The vitreous gel is replaced with a salt solution. Because the vitreous gel is mostly water, you will notice no change between the salt solution and the original vitreous gel.

What are the treatments for Diabetic Retinopathy ?

Yes. Both treatments are very effective in reducing vision loss. People with proliferative retinopathy can reduce their risk of blindness by 95 percent with timely treatment and appropriate follow-up care. Although both treatments have high success rates, they do not cure diabetic retinopathy. Once you have proliferative retinopathy, you always will be at risk for new bleeding. You may need treatment more than once to protect your sight.

What to do for Diabetic Retinopathy ?

If you have diabetes, get a comprehensive dilated eye exam at least once a year. Proliferative retinopathy can develop without symptoms. If it gets to this advanced stage, you are at high risk for vision loss or even blindness. Macular edema can develop without symptoms at any of the four stages of diabetic retinopathy. You can develop both proliferative retinopathy and macular edema and still see fine. However, you are at high risk for vision loss. Your eye care professional can tell if you have macular edema or any stage of diabetic retinopathy. Whether or not you have symptoms, early detection and timely treatment can prevent vision loss.

What is (are) Balance Problems ?

Have you ever felt dizzy, lightheaded, or as if the room were spinning around you? These can be very troublesome sensations. If the feeling happens often, it could be a sign of a balance problem. Balance problems are among the most common reasons that older adults seek help from a doctor. In 2008, an estimated 14.8 percent of American adults (33.4 million) had a balance or dizziness problem during the past year. Why Good Balance is Important Having good balance means being able to control and maintain your body's position, whether you are moving or remaining still. An intact sense of balance helps you - walk without staggering - get up from a chair without falling - climb stairs without tripping - bend over without falling. walk without staggering get up from a chair without falling climb stairs without tripping bend over without falling. The part of the inner ear responsible for balance is the vestibular system, often referred to as the labyrinth. To maintain your body's position, the labyrinth interacts with other systems in the body, such as the eyes, bones and joints. Good balance is important to help you get around, stay independent, and carry out daily activities. Learn how your body maintains its balance. When People Have Problems with Balance As they get older, many people experience problems with their sense of balance. They feel dizzy or unsteady, or as if they or their surroundings were in motion. Disturbances of the inner ear are a common cause. Vertigo, the feeling that you or the things around you are spinning, is also a common symptom. Balance disorders are one reason older people fall. Falls and fall-related injuries, such as hip fracture, can have a serious impact on an older person's life. If you fall, it could limit your activities or make it impossible to live independently. Many people often become more isolated after a fall. According to the Centers for Disease Control and Prevention, roughly more than one-third of adults ages 65 years and older fall each year. Among older adults, falls are the leading cause of injury-related deaths. Learn other ways a fall may affect an older adult's life. BPPV (Benign Paroxysmal Positional Vertigo) There are many types of balance disorders. One of the most common is benign paroxysmal positional vertigo, or BPPV. In BPPV, you experience a brief, intense feeling of vertigo when you change the position of your head, such as when rolling over to the left or right, upon getting out of bed, or when looking for an object on a high or low shelf. BPPV is more likely to occur in adults aged 60 and older, but can also occur in younger people. In BPPV, small calcium particles in the inner ear become displaced and disrupt the inner ear balance sensors, causing dizziness. The reason they become displaced is not known; the cause may be an inner ear infection, head injury, or aging. Labyrinthitis This is an infection or inflammation of the inner ear that causes dizziness and loss of balance. It is often associated with an upper respiratory infection such as the flu. Mnire's Disease Mnire's disease is a balance disorder that causes a person to experience - vertigo - hearing loss that comes and goes - tinnitus, which is a ringing or roaring in the ears - a feeling of fullness in the ear. vertigo hearing loss that comes and goes tinnitus, which is a ringing or roaring in the ears a feeling of fullness in the ear. It affects adults of any age. The cause is unknown. See a fuller list of balance disorders. There are many ways to treat balance disorders. Treatments vary depending on the cause. See your doctor if you are experiencing dizziness, vertigo, or other problems with your balance.

How to prevent Balance Problems ?

People are more likely to have problems with balance as they get older. But age is not the only reason these problems occur; there are other causes, too. In some cases, you can help reduce your risk for certain balance problems. Problems in the Inner Ear Some balance disorders are caused by problems in the inner ear. The part of the inner ear that is responsible for balance is the vestibular system, also known as the labyrinth. When the labyrinth becomes infected or swollen, this condition is called labyrinthitis. It is typically accompanied by vertigo and imbalance. Upper respiratory infections and other viral infections, and, less commonly, bacterial infections, can lead to labyrinthitis. Other Causes Other balance diseorers may involve another part of the body, such as the brain or the heart. For example, diseases of the circulatory system, such as stroke, can cause dizziness and other balance problems. Smoking and diabetes can increase the risk of stroke. Low blood pressure can also cause dizziness. Aging, infections, head injury and many medicines may also result in a balance problem. Problems Caused by Medications Balance problems can also result from taking many medications. For example, some medicines, such as those that help lower blood pressure, can make a person feel dizzy. Ototoxic drugs are medicines that damage the inner ear. If your medicine is ototoxic, you may feel off balance. Sometimes the damage lasts only as long as you take the drug; many times it is permanent. Groups of drugs that are more likely to be ototoxic include - antidepressants - anti-seizure drugs (anticonvulsants) - hypertensive (high blood pressure) drugs - sedatives - tranquilizers - anxiolytics (anti-anxiety drugs) - aminoglycosides (a type of antibiotic) - diuretics - vasodilators - certain analgesics (painkillers) - certain chemotherapeutics (anti-cancer drugs). antidepressants anti-seizure drugs (anticonvulsants) hypertensive (high blood pressure) drugs sedatives tranquilizers anxiolytics (anti-anxiety drugs) aminoglycosides (a type of antibiotic) diuretics vasodilators certain analgesics (painkillers) certain chemotherapeutics (anti-cancer drugs). Check with your doctor if you notice a problem while taking a medication. Ask if other medications can be used instead. If not, ask if the dosage can be safely reduced. Sometimes it cannot. However, your doctor will help you get the medication you need while trying to reduce unwanted side effects. Diet and Lifestyle Can Help Your diet and lifestyle can help you manage certain balance-related problems. For example, Mnire's disease, which causes vertigo and other balance and hearing problems, is linked to a change in the volume of fluid in the inner ear. By eating low-salt (low-sodium) or salt-free foods, and steering clear of caffeine and alcohol, you may make Mnire's disease symptoms less severe. See suggestions for limiting salt (sodium) in your diet. Balance problems due to high blood pressure can be managed by eating less salt (less sodium), maintaining a healthy weight, and exercising. Balance problems due to low blood pressure may be managed by drinking plenty of fluids, such as water, avoiding alcohol, and being cautious regarding your body's posture and movement, such as standing up slowly and avoiding crossing your legs when youre seated. Learn more about managing high blood pressure (hypertension). Learn more about manging low blood pressure (hypotension). Prevent Ear Infections The ear infection called otitis media is common in children, but adults can get it too. Otitis media can sometimes cause dizziness. You can help prevent otitis media by washing your hands frequently. Also, talk to your doctor about getting a yearly flu shot to stave off flu-related ear infections. If you still get an ear infection, see a doctor immediately before it becomes more serious. Learn more about otitis media and other ear infections. (Centers for Disease Control and Prevention)

What are the symptoms of Balance Problems ?

Some people may have a balance problem without realizing it. Others might think they have a problem, but are too embarrassed to tell their doctor, friends, or family. Here are common symtoms experienced by people with a balance disorder. Symptoms If you have a balance disorder, you may stagger when you try to walk, or teeter or fall when you try to stand up. You might experience other symptoms such as: - dizziness or vertigo (a spinning sensation) - falling or feeling as if you are going to fall - lightheadedness, faintness, or a floating sensation - blurred vision - confusion or disorientation. dizziness or vertigo (a spinning sensation) falling or feeling as if you are going to fall lightheadedness, faintness, or a floating sensation blurred vision confusion or disorientation. Other symptoms might include nausea and vomiting, diarrhea, changes in heart rate and blood pressure, and fear, anxiety, or panic. Symptoms may come and go over short time periods or last for a long time, and can lead to fatigue and depression. Diagnosis Can Be Difficult Balance disorders can be difficult to diagnose. Sometimes they are a sign of other health problems, such as those affecting the brain, the heart, or circulation of the blood. People may also find it hard to describe their symptoms to the doctor. Questions to Ask Yourself You can help identify a balance problem by asking yourself some key questions. If you answer "yes" to any of these questions, you should discuss the symptom with your doctor. - Do I feel unsteady? - Do I feel as if the room is spinning around me, even only for brief periods of time? - Do I feel as if I'm moving when I know I'm standing or sitting still? - Do I lose my balance and fall? - Do I feel as if I'm falling? - Do I feel lightheaded, or as if I might faint? - Does my vision become blurred? - Do I ever feel disoriented, losing my sense of time, place, or identity? Do I feel unsteady? Do I feel as if the room is spinning around me, even only for brief periods of time? Do I feel as if I'm moving when I know I'm standing or sitting still? Do I lose my balance and fall? Do I feel as if I'm falling? Do I feel lightheaded, or as if I might faint? Does my vision become blurred? Do I ever feel disoriented, losing my sense of time, place, or identity? Questions to Ask Your Doctor If you think that you have a balance disorder, you should schedule an appointment with your family doctor. You can help your doctor make a diagnosis by writing down key information about your dizziness or balance problem beforehand and giving the information to your doctor during the visit. Tell your doctor as much as you can. Write down answers to these questions for your doctor: - How would you describe your dizziness or balance problem? - If it feels like the room is spinning around you, which ways does it appear to turn? - How often do you have dizziness or balance problems? - Have you ever fallen? - If so, when did you fall, where did you fall, and how often have you fallen? - What medications do you take? Remember to include all over-the-counter medications, including aspirin, antihistamines, and sleep aids. - What is the name of the medication? - How much do you take each day? - What times of the day do you take the medication? - What is the health condition for which you take the medication? How would you describe your dizziness or balance problem? If it feels like the room is spinning around you, which ways does it appear to turn? How often do you have dizziness or balance problems? Have you ever fallen? If so, when did you fall, where did you fall, and how often have you fallen? What medications do you take? Remember to include all over-the-counter medications, including aspirin, antihistamines, and sleep aids. What is the name of the medication? How much do you take each day? What times of the day do you take the medication? What is the health condition for which you take the medication? See a video about describing symptoms and health concerns during a doctor visit. Seeing a Specialist Your doctor may refer you to an otolaryngologist. This is a doctor with special training in problems of the ear, nose, throat, head, and neck. The otolaryngologist may ask you for your medical history and perform a physical examination to help figure out the possible causes of the balance disorder. He or she, as well as an audiologist (a person who specializes in assessing hearing and balance disorders), may also perform tests to determine the cause and extent of the problem. Learn what's involved in visiting a medical specialist.

What are the treatments for Balance Problems ?

Your doctor can recommend strategies to help reduce the effects of a balance disorder. Scientists are studying ways to develop new, more effective methods to treat and prevent balance disorders. Balance disorders can be signs of other health problems, such as an ear infection, stroke, or multiple sclerosis. In some cases, you can help treat a balance disorder by seeking medical treatment for the illness that is causing the disorder. Exercises for Balance Disorders Some exercises help make up for a balance disorder by moving the head and body in certain ways. The exercises are developed especially for a patient by a professional (often a physical therapist) who understands the balance system and its relationship with other systems in the body. In benign paroxysmal positional vertigo, or BPPV, small calcium particles in the inner ear become displaced, causing dizziness. BPPV can often be effectively treated by carefully moving the head and torso to move the displaced calcium particles back to their original position. For some people, one session will be all that is needed. Others might need to repeat the procedure several times at home to relieve their dizziness. Treating Mnire's Disease Mnire's disease is caused by changes in fluid volumes in the inner ear. People with Mnire's disease can help reduce its dizzying effects by lowering the amount of sodium, or salt (sodium) in their diets. Limiting alcohol or caffeine also may be helpful. See suggestions for limiting salt (sodium) in your diet. Medications such as corticosteroids and the antibiotic gentamicin are used to treat Mnire's disease. Gentamicin can help reduce the dizziness that occurs with Mnire's disease, but in some cases it can also destroy sensory cells in the inner ear, resulting in permanent hearing loss. Corticosteroids don't cause hearing loss, but research is underway to determine if they are as effective as gentamicin. Learn more about ways to treat Mnire's disease. In some cases, surgery may be necessary to relieve a balance disorder. Treating Problems Due to High or Low Blood Pressure Balance problems due to high blood pressure can be managed by eating less salt (sodium), maintaining a healthy weight, and exercising. Balance problems due to low blood pressure may be managed by drinking plenty of fluids, such as water, avoiding alcohol, and being cautious regarding your body's posture and movement, such as standing up slowly and avoiding crossing your legs when youre seated. Learn more about managing high blood pressure (hypertension). Learn more about managing low blood pressure (hypotension). Coping with a Balance Disorder Some people with a balance disorder may not be able to fully relieve their dizziness and will need to find ways to cope with it. A vestibular rehabilitation therapist can help you develop an individualized treatment plan. Talk to your doctor about whether its safe to drive, as well as ways to lower your risk of falling and getting hurt during daily activities, such as when you walk up or down stairs, use the bathroom, or exercise. To reduce your risk of injury from dizziness, avoid walking in the dark. You should also wear low-heeled shoes or walking shoes outdoors. If necessary, use a cane or walker and modify conditions at your home and workplace, such as by adding handrails. Current Research Scientists are working to understand the complex interactions between the brain and the part of the inner ear responsible for balance. They are also studying the effectiveness of certain exercises as a treatment option for balance disorders. In a study funded by the National Institute on Deafness and Other Communication Disorders (NIDCD), researchers created a virtual reality grocery store. This virtual store is a computer-simulated environment that seems to be a physical place in the real world, designed so people with balance disorders can safely walk on a treadmill as they practice looking for items on store shelves. The goal is to help reduce a person's dizziness in confusing environments. NIDCD-supported scientists are also studying the use of a vestibular implant to stop a Mnires attack by restoring normal electrical activity in the vestibular nerve. This nerve conveys balance information to the brain. The device uses the same technology found in a cochlear implant, a medical device that currently provides a sense of sound to people who are deaf or hard-of-hearing. An NIDCD-supported clinical trial in benign paroxysmal positioning vertigo (BPPV) showed that repositioning maneuvers work well, and offered clinicians a range of choices in selecting the treatment best suited to each individuals unique needs.

A balance disorder is a disturbance of the body systems controlling balance. This disturbance can make people feel dizzy, unsteady, or as if they were spinning. Balance disorders are a common cause of falls and fall-related injuries, such as hip fractures.

How many people are affected by Balance Problems ?

In 2008, an estimated 14.8 percent of American adults (33.4 million) had a balance or dizziness problem during the past year. See statistics about the frequency of balance and other sensory impairments in older adults. (Centers for Disease Control and Prevention)

What are the symptoms of Balance Problems ?

If you have a balance disorder, you may stagger when you try to walk, or teeter or fall when you try to stand up. You might experience other symptoms such as - dizziness or vertigo (a spinning sensation) - falling or feeling as if you are going to fall - lightheadedness, faintness, or a floating sensation - blurred vision - confusion or disorientation. dizziness or vertigo (a spinning sensation) falling or feeling as if you are going to fall lightheadedness, faintness, or a floating sensation blurred vision confusion or disorientation. Other symptoms might include nausea and vomiting, diarrhea, changes in heart rate and blood pressure, and fear, anxiety, or panic. Symptoms may come and go over short time periods or last for a long time, and can lead to fatigue and depression.

What is (are) Balance Problems ?

There are many types of balance disorders. Three of the most common are BPPV (benign paroxysmal positional vertigo), labyrinthitis, and Menieres disease. BPPV (benign paroxysmal positional vertigo) is one of the most common balance disorders among older adults. With BPPV, you experience a brief, intense feeling of vertigo that occurs when you change the position of your head. You may also experience BPPV when rolling over to the left or right upon getting out of bed, or when looking up for an object on a high shelf. In BPPV, small calcium particles in the inner ear become displaced, causing dizziness. The reason the particles get displaced is not known, although it may result from an inner ear infection, head injury, or aging. Labyrinthitis is is another type of balance disorder. The labyrinth is an organ of the inner ear that helps you maintain your balance. When the labyrinth becomes infected or swollen, it is typically accompanied by vertigo and imbalance. Upper respiratory infections and other viral infections, and, less commonly, bacterial infections, can lead to labyrinthitis. Mnire's disease is a balance disorder that causes - vertigo - hearing loss that comes and goes - tinnitus, which is a ringing or roaring in the ears - a feeling of fullness in the ear. vertigo hearing loss that comes and goes tinnitus, which is a ringing or roaring in the ears a feeling of fullness in the ear. Mnire's disease can affect adults of any age. The cause is unknown. See a fuller list of balance disorders.

What causes Balance Problems ?

Some balance disorders are caused by problems in the inner ear. The part of the inner ear that is responsible for balance is the vestibular system, often refered to as the labyrinth. When the labyrinth becomes infected or swollen -- a condition called labyrinthitis -- it is typically accompanied by vertigo and imbalance. Upper respiratory infections, other viral infections, and, less commonly, bacterial infections, can lead to labyrinthitis. Other balance disorders may involve another part of the body, such as the brain or the heart. For example, diseases of the circulatory system, such as stroke, can cause dizziness and other balance problems. Smoking and diabetes can increase the risk of stroke. Low blood pressure also can cause dizziness. Aging, infections, head injury, and many medicines may also result in a balance problem.

What causes Balance Problems ?

Yes. Many prescription medications, such as those used to lower blood pressure, can make a person feel dizzy. Other medicines might damage the inner ear. These medicines, called ototoxic medicines, can make you feel off balance. Sometimes the damage lasts only as long as you take the drug. Other times it is permanent. Groups of drugs that are more likely to be ototoxic include - antidepressants - anti-seizure drugs (anticonvulsants) - hypertensive (high blood pressure) drugs - sedatives - tranquilizers - anxiolytics (anti-anxiety drugs) - aminoglycosides (a type of antibiotic) - diuretics - vasodilators - certain analgesics (painkillers) - certain chemotherapeutics (anti-cancer drugs). antidepressants anti-seizure drugs (anticonvulsants) hypertensive (high blood pressure) drugs sedatives tranquilizers anxiolytics (anti-anxiety drugs) aminoglycosides (a type of antibiotic) diuretics vasodilators certain analgesics (painkillers) certain chemotherapeutics (anti-cancer drugs).

How to prevent Balance Problems ?

An ear infection called otitis media can cause balance problems. Otitis media is most common in children, but adults can get it, too. You can help prevent otitis media by washing your hands frequently. Also, talk to your doctor about getting a yearly flu shot to stave off flu-related ear infections. If you do get an ear infection, see a doctor immediately before it becomes more serious. Learn more about otitis media and other ear infections. (Centers for Disease Control and Prevention)

You can help your doctor make a diagnosis by writing down key information about your dizziness or balance problem beforehand and giving the information to your doctor during the visit. Write down answers to these questions for your doctor: - How would you describe your dizziness or balance problem? - If the room is spinning around you, which ways does it appear to turn? - How often do you have dizziness or balance problems? - Have you ever fallen? - If so, when did you fall, where did you fall, and how often have you fallen? Tell your doctor as much as you can. - What medications do you take? Remember to include all over-the-counter medicines, including aspirin, antihistamines, or sleep aids. - What is the name of the medication? - How much medication do you take each day? - What times of the day do you take the medication? - What is the health condition for which you take the medication?

What are the treatments for Balance Problems ?

In BPPV (benign paroxysmal positional vertigo), small calcium particles in the inner ear become displaced, causing dizziness. A doctor, otolaryngologist, audiologist, or physical therapist can treat BPPV by carefully moving the head and torso to move the displaced calcium particles back to their original position Learn more about causes and treatments for BPPV. An NIDCD-supported clinical trial in BPPV showed that repositioning maneuvers work well, and offered clinicians a range of choices in selecting the treatment best suited to each individuals unique needs.

What are the treatments for Balance Problems ?

Mnire's disease is caused by changes in fluid volumes in the inner ear. People with Mnire's disease can help reduce its dizzying effects by lowering the amount of salt (sodium) in their diets. Limiting alcohol or caffeine also may be helpful. Some medications, such as corticosteroids or the antibiotic gentamicin, also are used to treat Mnire's disease. Although gentamicin can help reduce the dizziness that occurs with Mnire's disease, it occasionally destroys sensory cells in the inner ear, which can result in permanent hearing loss. Corticosteroids don't cause hearing loss; however, research is underway to determine if they are as effective as gentamicin Learn more about the treatments for Mnire's disease.

Scientists are working to understand the complex interactions between the brain and the part of the inner ear responsible for balance. They are also studying the effectiveness of certain exercises as a treatment option for balance disorders. An NIDCD-supported clinical trial in benign paroxysmal positioning vertigo (BPPV) showed that repositioning maneuvers work well, and offered clinicians a range of choices in selecting the treatment best suited to each individuals unique needs. NIDCD-funded researchers have created a virtual reality grocery store. This virtual store is a computer-simulated environment that seems to be a physical place in the real world. It is designed so people with balance disorders can safely walk on a treadmill as they practice looking for items on store shelves. The goal is to help reduce a person's dizziness in confusing environments. NIDCD-supported scientists are also studying the use of a vestibular implant to stop a Mnires attack by restoring normal electrical activity in the vestibular nerve. This nerve conveys balance information to the brain. The device uses the same technology found in a cochlear implant, a medical device that currently provides a sense of sound to people who are deaf or hard-of-hearing.

What is (are) Gum (Periodontal) Disease ?

An Infection of the Gums and Surrounding Tissues Gum (periodontal) disease is an infection of the gums and surrounding tissues that hold teeth in place. The two forms of gum disease are gingivitis, a mild form that is reversible with good oral hygiene, and periodontitis, a more severe form that can damage the soft tissues and bone that support teeth. If left untreated, periodontitis can lead to tooth loss. In its early stages, gum disease is usually painless, and many people are not aware that they have it. In more advanced cases, gum disease can cause sore gums and pain when chewing. Not A Normal Part of Aging The good news is that gum disease can be prevented. It does not have to be a part of growing older. With thorough brushing and flossing and regular professional cleanings by your dentist, you can reduce your risk of developing gum disease as you age. If you have been treated for gum disease, sticking to a proper oral hygiene routine and visiting your dentist for regular cleanings can minimize the chances that it will come back. Plaque Buildup Can Form Tartar Gum disease is typically caused by poor brushing and flossing habits that allow dental plaque -- a sticky film of bacteria -- to build up on the teeth. Plaque that is not removed can harden and form tartar that brushing doesn't clean. Only a professional cleaning by a dentist or dental hygienist can remove tartar. Gum disease can range from simple gum inflammation to serious disease. The two forms of gum disease are gingivitis and periodontitis. Gingivitis and Periodontitis In gingivitis, the gums become red, swollen and can bleed easily. Gingivitis can usually be reversed with daily brushing and flossing, and regular cleaning by a dentist or dental hygienist. This form of gum disease does not include any loss of bone and tissue that hold teeth in place. When gingivitis is not treated, it can advance to periodontitis. In periodontitis, gums pull away from the teeth and form spaces (called "pockets") that become infected. The body's immune system fights the bacteria as the plaque spreads and grows below the gum line. Bacterial toxins and the body's natural response to infection start to break down the bone and connective tissue that hold teeth in place. If not treated, the bones, gums, and tissue that support the teeth are destroyed. The teeth may eventually become loose and may have to be removed.

Risk Factors There are a number of risk factors that can increase your chances of developing periodontal disease. - Smoking is one of the most significant risk factors associated with the development of gum disease. Smoking can also lower the chances for successful treatment. - Hormonal changes in women can make gums more sensitive and make it easier for gingivitis to develop. - People with diabetes are at higher risk for developing infections, including gum disease. - Diseases like cancer or AIDS and their treatments can also negatively affect the health of gums. - There are hundreds of prescription and over-the-counter medications that can reduce the flow of saliva, which has a protective effect on the mouth. Without enough saliva, the mouth is vulnerable to infections such as gum disease. And some medicines can cause abnormal overgrowth of the gum tissue; this can make it difficult to keep teeth and gums clean. - Some people are more prone to severe gum disease because of their genetic makeup.

What are the symptoms of Gum (Periodontal) Disease ?

Symptoms Symptoms of gum disease may include: - bad breath that won't go away - red or swollen gums - tender or bleeding gums - painful chewing - loose teeth - sensitive teeth - receding gums or longer appearing teeth bad breath that won't go away red or swollen gums tender or bleeding gums painful chewing loose teeth sensitive teeth receding gums or longer appearing teeth If You Have Symptoms Any of these symptoms may be a sign of a serious problem that should be checked by a dentist. Sometimes gum disease has no clear symptoms. At your dental visit, the dentist or hygienist should - ask about your medical history to identify any conditions or risk factors (such as smoking) that may contribute to gum disease. - examine your gums and note any signs of inflammation. - use a tiny ruler called a 'probe' to check for and measure any pockets. In a healthy mouth, the depth of these pockets is usually between 1 and 3 millimeters.

What are the treatments for Gum (Periodontal) Disease ?

Controlling the Infection The main goal of treatment is to control the infection. The number and types of treatment will vary, depending on how far the disease has advanced. Any type of treatment requires the patient to keep up good daily care at home. The doctor may also suggest changing certain behaviors, such as quitting smoking, as a way to improve treatment outcome. Treatments may include deep cleaning, medications, surgery, and bone and tissue grafts. Deep Cleaning (Scaling and Planing) In deep cleaning, the dentist, periodontist, or dental hygienist removes the plaque through a method called scaling and root planing. Scaling means scraping off the tartar from above and below the gum line. Root planing gets rid of rough spots on the tooth root where the germs gather, and helps remove bacteria that contribute to the disease. In some cases a laser may be used to remove plaque and tartar. This procedure can result in less bleeding, swelling, and discomfort compared to traditional deep cleaning methods. Medications Medications may be used with treatment that includes scaling and root planing, but they cannot always take the place of surgery. Depending on how far the disease has progressed, the dentist or periodontist may still suggest surgical treatment. Long-term studies are needed to find out if using medications reduces the need for surgery and whether they are effective over a long period of time. Flap Surgery Surgery might be necessary if inflammation and deep pockets remain following treatment with deep cleaning and medications. A dentist or periodontist may perform flap surgery to remove tartar deposits in deep pockets or to reduce the periodontal pocket and make it easier for the patient, dentist, and hygienist to keep the area clean. This common surgery involves lifting back the gums and removing the tartar. The gums are then sutured back in place so that the tissue fits snugly around the tooth again. After surgery, the gums will shrink to fit more tightly around the tooth. This sometimes results in the teeth appearing longer. Bone and Tissue Grafts In addition to flap surgery, your periodontist or dentist may suggest procedures to help regenerate any bone or gum tissue lost to periodontitis. - Bone grafting, in which natural or synthetic bone is placed in the area of bone loss, can help promote bone growth. A technique that can be used with bone grafting is called guided tissue regeneration. In this procedure, a small piece of mesh-like material is inserted between the bone and gum tissue. This keeps the gum tissue from growing into the area where the bone should be, allowing the bone and connective tissue to regrow.

In cases where gum tissue has been lost, your dentist or periodontist may suggest a soft tissue graft, in which synthetic material or tissue taken from another area of your mouth is used to cover exposed tooth roots. Since each case is different, it is not possible to predict with certainty which grafts will be successful over the long-term. Treatment results depend on many things, including how far the disease has progressed, how well the patient keeps up with oral care at home, and certain risk factors, such as smoking, which may lower the chances of success. Ask your periodontist what the level of success might be in your particular case. Treatment Results Treatment results depend on many things, including how far the disease has progressed, how well the patient keeps up with home care, and certain risk factors, such as smoking, which may lower the chances of success. Ask your periodontist what the likelihood of success might be in your particular case. Consider Getting a Second Opinion When considering any extensive dental or medical treatment options, you should think about getting a second opinion. To find a dentist or periodontist for a second opinion, call your local dental society. They can provide you with names of practitioners in your area. Also, dental schools may sometimes be able to offer a second opinion. Call the dental school in your area to find out whether it offers this service.

If left untreated, gum disease can lead to tooth loss. Gum disease is the leading cause of tooth loss in older adults.

What causes Gum (Periodontal) Disease ?

In some studies, researchers have observed that people with periodontal disease (when compared to people without periodontal disease) were more likely to develop heart disease or have difficulty controlling their blood sugar. But so far, it has not been determined whether periodontal disease is the cause of these conditions. There may be other reasons people with periodontal disease sometimes develop additional health problems. For example, something else may be causing both the gum disease and the other condition, or it could be a coincidence that gum disease and other health problems are present together. More research is needed to clarify whether gum disease actually causes health problems beyond the mouth, and whether treating gum disease can keep other health conditions from developing. In the meantime, it's a fact that controlling periodontal disease can save your teeth -- a very good reason to take care of your teeth and gums.

Who is at risk for Gum (Periodontal) Disease? ?

There are a number of risk factors that can increase your chances of developing periodontal disease. - Smoking is one of the most significant risk factors associated with the development of gum disease and can even lower the chances for successful treatment. - Hormonal changes in women can make gums more sensitive and make it easier for gingivitis to develop. - Diabetes puts people at higher risk for developing infections, including gum disease. - Diseases like cancer or AIDS and their treatments can also affect the health of gums. - There are hundreds of prescription and over-the-counter medications that can reduce the flow of saliva, which has a protective effect on the mouth.
