What
is a Stroke?
Stroke is a sudden
interruption in the blood supply of the brain. Most strokes are
caused by an abrupt blockage of arteries leading to the brain (ischemic
stroke). Other strokes are caused by bleeding into brain
tissue when a blood vessel bursts (hemorrhagic stroke).
Because stroke occurs rapidly and requires immediate treatment, stroke
is also called a brain attack. When the symptoms of a
stroke last only a short time (less than 24 hourS), this is called a transient
ischemic attack (TIA) or mini-stroke.
