A cerebrovascular accident (or a stroke) occurs when the blood supply is cut off to the brain.
An infarct or dead area develops.
Causes:
   • Hemorrhagic—ruptured blood vessel
   • Embolus—a floating clot lodges in a cerebral vessel
   • Thrombus—a stationary clot forms within a cerebral blood vessel
   • Compression—a space-occupying lesion (like a tumor) pinches off an adjacent blood vessel
