Put this in you own words...
Ischemic 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.
