Put this in you own

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.

The passage listed above in my own words:

Ischemic strokes are the most common type of stroke. They occur when a blood vessel that leads to the brain becomes clogged usually by blood clots, which are clumps of blood that stick together. The blood sticks together in order to stop bleeding. However, they often form inappropriately inside an artery or vein , causing the blood flow to decrease and the blood can't get where it needs to be. Another reason for Ischemic strokes is because sometimes, arteries become narrow and clogged, usually with plaque, which is a mix of fatty stuff and cholesterol that stick to the walls of blood vessels.
