Final answer:
A hemorrhagic stroke is a type of stroke that occurs due to bleeding within the brain, damaging brain tissue. It is less common than ischemic strokes but has a higher fatality rate. Treatment may involve surgery to relieve pressure in the brain.
Step-by-step explanation:
A hemorrhagic stroke is a type of stroke that results from bleeding within the brain, which damages brain tissue. It occurs when an artery in the brain ruptures and causes bleeding, putting pressure on brain tissue and depriving downstream tissues of adequate blood flow. Hemorrhagic strokes are less common than ischemic strokes, but they are more likely to be fatal. Treatment for hemorrhagic stroke may involve surgery to relieve pressure in the brain.
