Types of Strokes
A stroke can happen if something keeps the blood from flowing as it should. A person might have a clogged blood vessel, so the blood can't get through. Or a blood vessel may burst and a part of the brain is suddenly flooded with blood. Either way, with a stroke, brain cells die because they don't get the oxygen they need.
There are two main types of strokes:
Strokes are serious. People who have strokes can get really sick, have brain damage, or die. But many people recover from strokes, especially if they know the warning signs and can get help quickly.

There are two main types of strokes:
- Ischemic (say: iss-KEE-mik) strokes happen when a blood vessel going to the brain becomes blocked, and the blood can't get where it's supposed to be. This type of stroke is the most common. A blood clot — a clump of blood that sticks together — is usually to blame for ischemic strokes. They can also happen when arteries become narrow and clogged with plaque. Plaque is a mix of cholesterol and other fatty stuff that sticks to the walls of blood vessels.
- Hemorrhagic (say: heh-muh-RAH-jik) strokes happen when a weak or thin blood vessel bursts and the blood spills out, killing brain cells and affecting how the brain works. High blood pressure can weaken the walls of vessels and make a hemorrhagic stroke much more likely.

Pediatric Stroke
Strokes can happen at any point in a person's lifetime, from infancy to adulthood. Ischemic strokes, the most common type in children, are usually related to: lack of oxygen during birth. a heart defect present at birth. blood disorders such as sickle cell anemia, a disease that destroys blood cells and blocks blood vessels. injury to an artery (a blood vessel that brings oxygen) in the brain.
