Stroke

A cerebrovascular accident is also known as a stroke. A stroke is a life-threatening event in which part of the brain is deprived of adequate oxygen.

There are two kinds of strokes:

Ischemic strokes occur when the blood supply to the brain is interrupted, usually by a blood clot originating from the carotid arteries. These arteries feed the head and brain with oxygen-rich blood. The cause is usually atherosclerotic plaques in one of the arteries.
Hemorrhagic strokes occur when there is bleeding into or around the brain
