Brain ischemia. Brain ischemia (a.k.a. cerebral ischemia, cerebrovascular ischemia) is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. This leads to poor oxygen supply or cerebral hypoxia and thus to the death of brain tissue or cerebral infarction / ischemic stroke.
This pathology is called an ischemic stroke. The lack of blood supply destroys brain tissue and causes neurological damage. Another type of stroke, called a hemorrhagic stroke, occurs when an artery in the brain bursts and blood flows into the brain. < Next Article: Functions of the Blood: 8 Facts about Blood > Related Articles
