CEREBROVASCULAR ACCIDENT

Cerebrovascular accident is the term that refers to any functional abnormality of the Central Nervous System that occurs when the normal blood supply to the brain is disrupted, as by a blood clot or a ruptured blood vessel, and vital brain tissue dies. Cerebrovascular accident is commonly called Strokes.

Cerebrovascular accident may be caused by any of three mechanisms.

  • Cerebral Thrombosis – blockage in the thrombus (clot) that has built up on the wall of the brain artery.
  • Cerebral Embolism – blockage by an embolus (usually a clot) swept into the artery in the brain.
  • Hemorrhage – Rupture of a blood vessel and bleeding within or over the surface of the brain.
