Ischemic stroke is caused by a blood clot, while hemorrhagic stroke is caused by what?

• A. Ischemic stroke is caused by a ruptured artery; hemorrhagic stroke is caused by a blood clot
• B. Ischemic stroke is caused by a blood clot; hemorrhagic stroke is caused by a ruptured artery
• C. Ischemic stroke is caused by infection; hemorrhagic stroke is caused by immune reaction
• D. Both strokes are caused by high cholesterol

Answer: (B)

Ischemic stroke happens when a blood clot blocks a brain artery, stopping blood flow and oxygen to brain tissue. Hemorrhagic stroke occurs when a brain artery ruptures, causing bleeding into the brain and damage from both the loss of blood and the pressure of the bleed. So the correct idea is that one type is caused by a clot and the other by a rupture. The option that assigns a rupture to the ischemic stroke and a clot to the hemorrhagic stroke is incorrect. Saying both strokes come from high cholesterol isn’t accurate either; cholesterol can contribute to clot formation, but hemorrhagic stroke mainly results from vessel rupture, often related to hypertension or aneurysm.
