Strokes
Each year, more than 500,000
Americans have a stroke. A stroke is sometimes called a "brain
attack. "A stroke happens when the brain does not get enough blood.
This cuts off oxygen and kills brain cells.
Strokes can affect a person's
ability to speak, see, move, and think. Strokes may even cause death.
In fact, they are the third leading killer in the United States. And
they are the leading cause of disability in adults.
There are three major
types of stroke:
- Thrombotic(thrahm-bah-tik)
- Thrombotic strokes are caused by fat deposits (plaques) that have
built up in your arteries (blood vessels).
- Embolic(em-bah-lik)
- Embolic strokes are caused by a blood clot in another part of the
body.
- Hemorrhagic(hem-uh-ray-jik)
0 Hemorrhagic strokes are caused when an artery bleeds in the brain.
Who Gets Strokes?
- Most strokes happen to
adults over the age of 40. But younger adults and even children can
have them, too.
- About the same number of
men and women have strokes. All groups and races are at risk for
strokes. But african-Americans are almost two times as likely to
die from a stroke as whites. And they often suffer more damage.

Stroke

pressure - One out of three people with high blood pressure
doesn't know it. That's a problem, because high blood vessels in
the brain, increasing your chance of stroke. Also, high blood-glucose
levels at the time of a stroke usually lead to more brain damage
than when the glucose level is normal. So it's important to follow
your doctor's advice for controlling your diabetes.

Smoking can thicken your blood and cause dangerous clots. It can
also raise your blood pressure. Ask your doctor, pharmacist or nurse

Exercise makes the heart stronger and improves blood flow. It also
helps control weight. Being heavy increases your chance of diseases.

sure you visit doctor regularly.

for stroke-like symptoms - Don't ignore the signs of a "mini

a full-blown stroke later on. If you get any of the signs, see
a doctor right away.
