Stroke Awareness
What is a Stroke?
A stroke is a "brain attack," it occurs when an
artery bringing blood to the brain becomes clogged or ruptures,
depriving a part of the brain the oxygen it needs. As a
result, that part of the brain starts to die.
TIA's
About 10 percent of strokes are preceded by "temporary
strokes" (transient ischemic attacks TIA's) These can
occur days, weeks or even months before a major stroke.
They result when a blood clot temporarily clogs an artery.
The symptoms occur rapidly and are temporary, lasting from a few
minutes to several hours. People who have had TIA's are
10 times more likely to have a stroke

How the Body Heals
When ever the blood supply is cut off from one part of the
body, the body tries to restore circulation itself. Small
neighboring blood vessels get larger and assume the work of the
damaged ones. The part of the body affected by the stroke
may eventually improve with the additional help of rehabilitation
treatment
