“Mini-strokes” have major risks
What’s the difference between a stroke and a transient ischemic
attack (TIA)? At first, not much. They look the same, feel the same,
and stem from the same thing — blocked blood flow to the brain.
But a stroke lasts for hours, maybe longer, while a TIA fades away
after a few minutes.
Don’t be fooled by the disappearance of symptoms. Even after they
are gone, danger still lurks in the form of other TIAs, stroke, and even
A study published in the April 2005 Stroke looked at all the
people who had a TIA in the Cincinnati area during a single year. In
the three months following the mini-stroke, 1 in 7 people (14.6%) had
a full stroke, and 1 in 4 (25.2%) had either died or suffered a stroke
or another TIA.
British researchers, writing in the March 2005 Neurology, looked
at the connection from the other direction. Among more than 500 stroke
victims, 17% had experienced a TIA on the day of their stroke, 9% had
one on the day before, and a whopping 43% had a TIA sometime during the
week preceding the stroke.
These studies add to the mounting evidence that it’s time to take
TIAs seriously. If you think you or someone you are with is having one,
do the same thing you would do for a heart attack: Call 911.
Once the crisis has passed, your doctors should do two things: Start
looking for what caused the problem, and do what they can to prevent
a subsequent stroke or TIA.
Call 911 or your local emergency medical services number right
away if one or more of these symptoms suddenly happen to you
or someone else, even if they begin to fade away after a few
