Stroke Prevention
A stroke occurs when blood flow to the brain is blocked, either by narrowed blood vessels or blood clots or when there is bleeding in the brain. Deprived of nutrients, brain nerve cells begin to die within a few minutes. As a result, stroke can cause vision and sensory loss, problems with walking and talking, or difficulty in thinking clearly. In many cases, the effects of stroke are irreversible.
Some people are more at risk for stroke than others. Chronic health conditions such as high blood pressure and diabetes can increase your risk, as well as lifestyle choices such as smoking cigarettes, being overweight, or drinking excessively. Men, African Americans, and people with a family history of stroke have a higher risk as well. If you have already had a stroke or a transient ischemic attack (referred to as a TIA or "mini-stroke"), you are at highest risk. Warning signs include sudden unexplained numbness or tingling especially on one side), slurred speech, blurred vision, stumbling, or clumsiness.
Preventing Stroke
Experts now believe that stroke is as preventable as heart attack. In addition to primary prevention tactics such as quitting smoking, drinking only in moderation, and exercising, there are medical interventions that can decrease your risk of stroke if you are in a high-risk group. Recent studies, including those supported by the Agency for Health Care Policy and Research (AHCPR), show that if you have conditions known as atrial fibrillation or carotid artery disease, there are interventions that can dramatically lower your risk of stroke.
