Stroke Prevention (cont.)
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!
- Sudden numbness or weakness of 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. 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.
