Final answer:
The type of stroke that occurs during a stroke is determined by whether the blood supply is compromised due to a blockage or narrowing of the blood vessels (ischemic stroke) or bleeding from a broken blood vessel (hemorrhagic stroke).
Step-by-step explanation:
The two possible events during a stroke are ischemic stroke and hemorrhagic stroke.
Ischemic strokes occur due to a lack of blood flow caused by a blood clot in an artery going to the brain. On the other hand, hemorrhagic strokes occur due to bleeding from a broken blood vessel in the brain.
The type of stroke that occurs depends on how the blood supply is compromised: whether it is due to a blockage or narrowing of the blood vessels (ischemic stroke) or bleeding from a broken blood vessel (hemorrhagic stroke).
