Final answer:

Ischemic strokes result from blood clots causing a lack of blood flow in the brain, whereas hemorrhagic strokes involve bleeding from a broken blood vessel. Hemorrhagic strokes are rarer but more fatal than ischemic strokes.


Explanation:

Ischemic strokes occur due to a lack of blood flow because of a blood clot in an artery going to the brain, while hemorrhagic strokes occur due to bleeding from a broken blood vessel in the brain.

Ischemic strokes involve the occlusion of cerebral blood flow, while hemorrhagic strokes involve the leakage of blood flow.

Only about 10 percent of strokes are hemorrhagic strokes, but they are more likely to be fatal than ischemic strokes.
