Question

Quizplus · Accepted Answer

Ischemia from an obstruction of an artery is the most common cause of a stroke, accounting for approximately 85% of all strokes. This obstruction can be caused by a blood clot or a build-up of fatty deposits in the blood vessels. Lack of glucose or a blow to the head can cause brain damage, but may not necessarily result in a stroke. Hemorrhage of an artery is a less common cause of stroke.
