What is a Stroke?
A stroke or "brain attack" occurs when part of the brain is temporarily deprived of oxygen-rich blood. This happens when a blood clot blocks a blood vessel or artery, or a blood vessel breaks, interrupting blood flow to an area of the brain. When a stroke occurs, it kills brain cells in the area surrounding the clot or breakage.
There are 2 types of stroke:
Ischemic strokes account for approximately 87 percent of strokes and can occur two ways:
Embolic: Clot travels to the brain from another part of the body
Thrombotic: Clot develops in an artery
Hemorrhagic strokes occur when a blood vessel in the brain breaks or ruptures. While hemorrhagic stroke is less common, it’s more deadly.
