A stroke is a sudden brain injury caused by an interruption of blood flow (ischemic stroke) or by bleeding in the brain (hemorrhagic stroke). It is one of the most serious acute neurological conditions, often resulting in permanent disability or death, and remains a leading cause of long-term disability and secondary mortality both globally and in the United States. The modern clinical motto is: “Every minute counts – time is brain”—meaning that every moment without treatment leads to the loss of millions of brain cells.
Causes and Risk Factors Stroke is a complex condition with two primary types:
Ischemic stroke – caused by a blockage in a blood vessel (approximately 87% of all cases), most commonly due to thrombosis, embolism, or atherosclerosis.
Hemorrhagic stroke – results from the rupture of a blood vessel and bleeding into the brain.
