Cerebral ischemia

A pathophysiological state in which cerebral blood flow and oxygen delivery are insufficient to meet the brain's metabolic demands, due to reduced or interrupted perfusion, leading to neuronal dysfunction, potential infarction, and corresponding neurologic deficits.

Causes

• Thrombosis

• Embolism

• Cerebral atherosclerosis

• Myocardial infarction

• Severe hypotension: Shock, severe blood loss

• Sickle cell anemia

• External wessel compression from a growing tumor
