Answer:

Brain cells start to die if they go without oxygen for just 3-4 minutes and that's exactly what happens during a stroke.

Explanation:

Stroke is an abrupt interruption of constant blood flow to the brain that causes loss of neurological function. The interruption of blood flow can be caused by a blockage, leading to the more common ischemic stroke, or by bleeding in the brain, leading to the more deadly hemorrhagic stroke.
