Causes and Symptoms of Stroke - Oren Zarif - Stroke

Several causes of stroke exist. When a blood clot forms in the brain, it can block a major artery or it can burst, spilling blood into nearby tissues. A transient ischemic attack, or TISA, occurs when a temporary blood clot causes a "mini-stroke" without causing permanent damage or disability. While neither of these conditions is life threatening, they are warning signs of stroke and should be treated promptly. A person can suffer from a stroke at any time, and understanding the signs and symptoms can help prevent it from becoming serious in the future.

Treatment for stroke depends on the type of stroke, which affects various parts of the brain. The sooner it is diagnosed, the better the chances are of recovery. The sooner the stroke is diagnosed and treated, the better chance the patient will have of avoiding severe effects and death. Symptoms of stroke vary widely, but typically include difficulty speaking or understanding speech, numbness, and weakness on one side of the body. Sometimes, one side of the mouth may droop when smiling. Vision may also be affected. If a stroke is severe, the sufferer will experience double or blurred vision or blackouts.

If the symptoms of a stroke are unavoidable, the first step is to call 999 and request an ambulance. If the patient is conscious, but unable to speak or smile, they should be examined immediately to check for other underlying causes. The stroke patient's heart may be a victim of a blood clot. If there is a suspected blood clot, the patient can receive tPA, which is a medication used to dissolve it. It must be given within four hours of symptoms.

While stroke can strike anyone at any age, it is particularly common in people older than 65 and in families with a history of heart disease. In addition to smoking, high blood pressure can damage blood vessels in the brain, resulting in a stroke. High blood pressure also increases the risk of heart disease. Smoking can almost double the risk of an ischemic stroke. Stroke is a life-threatening condition, but there are ways to minimize its consequences.

A stroke, also known as transient ischemic attack or cerebrovascular accident, is when blood flow to the brain is interrupted. Without adequate blood flow, the brain cells die. This causes lasting damage and disability to brain tissue, including the ability to speak, think, and see. In some cases, it can even result in death. While many strokes are treatable, many are not, and immediate medical treatment is essential for a better outcome.

Treatments for strokes vary, but the most effective medications include clot-busting drugs and surgical procedures. These medications dissolve blood clots and restore blood flow to the affected area of the brain. The best time to administer a tPA injection is within four hours of the symptoms of the stroke. During emergency care, patients may receive blood-thinning drugs such as aspirin, warfarin, or heparin. If the stroke symptoms are severe, surgery may be necessary to remove the blood around the brain or repair damaged blood vessels.

There are two major types of stroke, ischemic and hemorrhagic. Ischemic stroke occurs when a clot forms in an artery in the brain. This blockage can occur due to high blood pressure, smoking, or other factors. Another type, embolic stroke, occurs when a blood clot breaks loose and travels to the brain. In these cases, the plaque that formed on the artery causes further damage to brain tissue.

While stroke is a traumatic event, many survivors can recover and live a full and productive life. In most cases, stroke occurs when a blood clot forms in a blood vessel leading to the brain. If the blood flow to the brain is interrupted, the clot may rupture or block the artery, which results in brain damage and death. Symptoms may vary and are caused by a number of factors, including certain health conditions and lifestyle habits.

In the U.S., stroke is the fifth leading cause of death and disability. In the United States, it affects close to 800,000 people each year - that's about one person every 40 seconds. Although ischemic stroke is the most common type of stroke, hemorrhagic stroke can also occur when a blood clot forms in a blood vessel supplying the brain. It's important to understand that treatment for stroke will differ based on the cause, but the outcomes can be disastrous for the sufferer.
