Answer: Cerebrovascular accidents induce brain damage either due to bleeding in the brain or obstruction of blood vessels. Hemorrhagic strokes are caused by bleeding within the brain related to a malformed blood vessel or high blood pressure. Obstructive cerebrovascular accidents are related to the plugging of a blood vessel by a thrombus (a blood clot) or an embolus (bacterial debris or a portion of clot).
