A stroke occurs when blood flow to part of the brain suddenly stops. It can happen because of a blood clot that blocks a blood vessel (ischemic stroke) or because a blood vessel in your brain bursts (hemorrhagic stroke). Your brain cells need oxygen and nutrients carried by the blood, so when a stroke happens, brain cells begin to die within minutes. Click the links below to learn more about strokes and how to respond when one is happening.
