The more common kind - representing 80 percent of all strokes - comes from a block in blood flow to part of the brain. That's called an ischemic stroke. The block is a clot in an artery feeding the brain. It's similar to what happens in a heart attack, when one of the heart arteries becomes plugged and blood cannot get to the heart muscle. The less common kind of stroke is due to bleeding from a brain blood vessel.See the full content of this document
