May 4, 2006 -- Today, tomorrow, and every day this year, roughly 1,900
strokes will be suffered by people in the U.S.
After heart disease
and cancer, strokes are
responsible for more American deaths than any other medical condition, but
experts say much could be done to change this.
Guidelines released today by the American StrokeAssociation
highlight some well-established and less well-known risk factors for stroke, as
well as measures people can take to lower their risk.
"We are making some progress, but we still have a big mountain to
climb," says Larry B. Goldstein, MD, who led the guidelines committee.
"People are more aware of stroke than they used to be. But far too many

Who Is at Risk
Low birth weight was recognized for the first time as a possible risk factor
for stroke, based on recent studies suggesting a doubling of risk among adults
who weighed less than 5.5 pounds at birth compared with those who weighed 8.8
pounds or more. The reason for this is unclear, and this association does not
mean that low birth weight causes stroke.
Other well established, nonmodifiable stroke risk factors include age, sex,
race or ethnic background, and family history. Elderly people, men, blacks, and
people with a family history of stroke tend to have a higher than average
The guidelines call for very aggressive stroke screening and prevention
efforts for children and adults with sickle cell disease. About 10% of children
with sickle cell will have had a stroke by the time they reach adulthood.
The committee report also called on doctors to assess their patients' stroke
risk using established tools.
Patients who know they are at risk for having a stroke tend to be more
motivated to make lifestyle changes and take their medication than patients who
are simply told they have cardiovascular disease, Goldstein says.
"We know that people greatly fear the consequences of stroke, such as
being unable to talk and understand, being unable to care for yourself, and
being unable move one side of your body," he tells WebMD.
