A stroke is an illness in which part of the brain loses its blood supply. This can happen if an artery that feeds blood to the brain gets clogged, or if it tears and leaks.

A stroke is when there is a lack of blood flow to the brain. There are two types of strokes. One is when there is a blood clot blocking the artery. The other type of stroke is when a blood vessel bursts and there is blood moving around freely in the brain.
