Question:
What are the symptoms of Stroke ?

Answer:
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.
Question:
What is (are) Stroke ?

Answer:
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.
Question:
Who is at risk for Stroke? ?

Answer:
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.
Question:
What is (are) Stroke ?

Answer:
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.

Question:
Who is at risk for Stroke? ?

Answer:
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.

Experiencing warning signs and having a history of stroke are also risk factors for stroke.
Question:
What is (are) Stroke ?

Answer:
Atherosclerosis, also known as hardening of the arteries, is the most common blood vessel disease. It is caused by the buildup of fatty deposits in the arteries, and is a risk factor for stroke.
Question:
How to prevent Stroke ?

Answer:
Yes. Stroke is preventable. 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. 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.  Managing your high blood pressure is the most important thing you can do to avoid stroke. See ways to manage high blood pressure.     -  If you smoke, quit.

Question:
How to diagnose Stroke ?

Answer:
Doctors have several 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 (CT) or magnetic resonance imaging (MRI) will often be done.
Question:
What is (are) Stroke ?

Answer:
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.
Question:
What is (are) Stroke ?

Answer:
The most commonly used imaging procedure is the computed tomography or CT scan, also known as a CAT scan. A CT scan is comprised of a series of cross-sectional images of the head and brain. Because it 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. 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.
Question:
What is (are) Stroke ?

Answer:
Another imaging technique used for 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. An MRI can show this type of damage very soon after the stroke symptoms start. 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). Also, MRI can be more sensitive than CT for detecting other types of neurologic 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. Also, MRI typically takes longer to perform than CT, and therefore may not be the first choice when minutes count.
Question:
What are the treatments for Stroke ?

Answer:
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.
Question:
What are the treatments for Stroke ?

Answer:
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.
Question:
what research (or clinical trials) is being done for Stroke ?

Answer:
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. Currently, scientists are 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. Scientists are also 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. 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. 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. Participating in a clinical study contributes to medical knowledge. The results of these studies can make a difference in the care of future patients by providing information about the benefits and risks of therapeutic, preventative, or diagnostic products or interventions.
Question:
What is (are) Stroke ?

Answer:
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.

Question:
What is (are) Psoriasis ?

Answer:
Psoriasis (sow RYE uh sis) is a chronic skin disease. Chronic means that it lasts a long time, often a lifetime. Psoriasis affects more than 5 million adults in the United States. It appears about equally in males and females. Psoriasis occurs when the skin cells grow too quickly. The body does not shed these excess cells and they build up on the surface of the skin, forming thick, scaly patches.   Types of Psoriasis Psoriasis occurs in five different forms that affect both men and women. Most people have only one type of psoriasis at a time. Sometimes, one type of psoriasis will disappear and another will appear. Here is a brief overview of the different forms of psoriasis. - Is the most common form  - appears as raised red patches covered in silvery white scales   - usually shows up on the scalp, knees, elbows and lower back   - patches may itch or be painful and can also crack and bleed.  Is the most common form appears as raised red patches covered in silvery white scales usually shows up on the scalp, knees, elbows and lower back patches may itch or be painful and can also crack and bleed. - is the second most common form of psoriasis  - usually begins in childhood or early adulthood   - appears as small red spots on the skin.  is the second most common form of psoriasis usually begins in childhood or early adulthood appears as small red spots on the skin. - appears as red sores in body folds, such as the groin and under the breasts  - is more common in people who are overweight   - often occurs along with another form of psoriasis.  appears as red sores in body folds, such as the groin and under the breasts is more common in people who are overweight often occurs along with another form of psoriasis. - features white blisters surrounded by red skin  - mainly affects adults  - may occur all over the body, but usually affects one area.  features white blisters surrounded by red skin mainly affects adults may occur all over the body, but usually affects one area. - is the rarest and most dangerous form of psoriasis   - is characterized by inflammation  - usually affects most of the body.  is the rarest and most dangerous form of psoriasis is characterized by inflammation usually affects most of the body.
Question:
What causes Psoriasis ?

Answer:
Although the cause of psoriasis is not completely understood, scientists believe it is related to a problem with a type of blood cells called T cells. These cells normally travel through the bloodstream to help fight an infection, but in people with psoriasis, they attack the bodys skin cells by mistake. Genes Play a Role No one knows what causes T cells to go wrong, but certain genes have been linked to psoriasis. People who have these genes are more likely to develop psoriasis than people without the genes. However, genes alone do not cause psoriasis. Scientists believe psoriasis occurs when something in the environment triggers the disease in someone who has one or more of these genes.  Psoriasis Triggers These so-called triggers may be different for different people. Different triggers may start the disease or make it worse in different people. Factors that may trigger psoriasis or make it worse include - physical and emotional stress  - injury to the skin such as cuts or burns  - infections, particularly strep throat  - cold weather   - smoking or heavy alcohol use  - certain medications such as     - lithium, a psychiatric drug   - antimalarials such as hydroxychloroquine and chloroquine    - inderal, a high blood pressure medicine   - quinidine, a heart medication   - indomethacin, a nonsteroidal anti-inflammatory drug often used to treat arthritis.   physical and emotional stress injury to the skin such as cuts or burns infections, particularly strep throat cold weather smoking or heavy alcohol use certain medications such as - lithium, a psychiatric drug  - antimalarials such as hydroxychloroquine and chloroquine   - inderal, a high blood pressure medicine  - quinidine, a heart medication  - indomethacin, a nonsteroidal anti-inflammatory drug often used to treat arthritis. lithium, a psychiatric drug antimalarials such as hydroxychloroquine and chloroquine inderal, a high blood pressure medicine quinidine, a heart medication indomethacin, a nonsteroidal anti-inflammatory drug often used to treat arthritis.
Question:
What are the symptoms of Psoriasis ?

Answer:
Different forms of psoriasis have different symptoms. In many cases your doctor can diagnose psoriasis based on the signs seen in the physical exam as well as the symptoms you describe. Symptoms The most common symptoms of psoriasis are - patches of thick, red skin   - skin inflammation  - silvery scales  - itching  - pain. patches of thick, red skin skin inflammation silvery scales itching pain. Psoriasis most commonly affects the elbows, knees, scalp, lower back, face, palms, soles of the feet, nails, and soft tissues. Making a Diagnosis In most cases, your primary care provider can diagnose psoriasis simply by examining your skin. Because the symptoms of psoriasis may be similar to those of other skin diseases, however, sometimes the diagnosis is more difficult. You may need to see a dermatologist, a doctor who specializes in diagnosing and treating skin diseases. If your doctor isn't sure if you have psoriasis, he or she may order a biopsy. This involves removing a small sample of skin and looking at it under a microscope.
