A cerebrovascular accident is a sudden disruption of blood flow to a region of the brain, depriving brain tissue of oxygen and nutrients. This interruption can occur because a vessel is blocked (ischemic stroke) or because a vessel ruptures and bleeds (hemorrhagic stroke). The term captures the idea of an abrupt disturbance in the brain’s blood supply, which leads to neuronal injury and neurologic deficits depending on the affected area.

The other options describe problems in other parts of the body or different conditions: a blockage of a coronary artery affects the heart (heart attack); inflammation of the meninges is meningitis; a blood clot in the leg is a deep vein thrombosis.
