What is a Stroke?
A stroke, or “brain attack,” occurs when blood circulation to the brain fails. Brain cells can die from decreased blood flow and the resulting lack of oxygen.
There are two broad categories of stroke:
1. Those caused by a blockage of blood flow and those caused by bleeding.
2. While not usually fatal, a blockage of a blood vessel in the brain or neck, called an ischemic stroke, is the most frequent cause of stroke and is responsible for about 80 percent of strokes.
Two key steps you can take will lower your risk of death or disability from stroke:
1. Know stroke’s warning signs
2. Control stroke’s risk factors
What are Warning Signs of a Stroke?
Warning signs are clues your body sends that your brain is not receiving enough oxygen. If you observe one or more of these signs of a stroke or “brain attack,” don’t wait, call a doctor or 911 right away:
Other danger signs that may occur include double vision, drowsiness, and nausea or vomiting. Sometimes the warning signs 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, they identify an underlying serious condition that isn’t going away without medical help. Unfortunately, since they clear up, many people ignore them. Don’t. Heeding them can save your life.
What are Risk Factors for a Stroke?
A risk factor is a condition or behavior that occurs more frequently in those who have, or are at greater risk of getting, a disease than in those who don’t. 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 increases.
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. In 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 United States. Scientists have found more and more severe risk factors in some minority groups and continue to look for patterns of stroke in these groups.
Managing stroke
Many risk factors for stroke can be managed, some very successfully. Although risk is never zero at any age, by starting early and controlling your risk factors you can lower your risk of death or disability from stroke. With good control, the risk of stroke in most age groups can be kept below that for accidental injury or death.
Americans have shown that stroke is preventable and treatable. In recent years, a better understanding of the causes of stroke has helped Americans make lifestyle changes that have cut the stroke death rate nearly in half.
