Cerebral ischemia is a condition in which a blockage in an artery restricts the delivery of oxygen-rich blood to the brain, resulting in damage to brain tissue. Cerebral ischemia is sometimes called brain ischemia or cerebrovascular ischemia.
Cerebral ischemia can lead not only to brain-cell damage but to brain-cell death. A transient ischemic attack (TIA), also known as a mini-stroke, is when the cerebral ischemia causes the temporary loss of brain function. An ischemic stroke, also known as a cerebral infarction or brain attack, results when a blood vessel is occluded and the loss of brain function is permanent because the brain tissue dies (sometimes called necrosis). Ischemic strokes are the most common form of stroke.
