Stroke Pathophysiology Sid Shah‚ MD Pathophysiology of Stroke Sid Shah‚ MD Page 2 of 14 Stroke Pathophysiology Introduction The two major mechanisms causing brain damage in stroke are‚ ischemia and hemorrhage. In ischemic stroke‚ which represents about 80% of all strokes‚ decreased or absent circulating blood deprives neurons of necessary substrates. The effects of ischemia are fairly rapid because the brain does not store glucose‚ the chief energy substrate and is incapable of anaerobic

STROKE A stroke is caused by an interruption of the blood supply to part of the brain. The term ‘stroke’ comes from the fact that it usually happens without any warning‚ ‘striking’ the person from out of the blue. Stroke is a medical emergency. If you suspect someone is having a stroke‚ call 999. Worldwide‚ every year 2 in every 1‚000 people have a stroke. Five out of six strokes happen in people over the age of 60. Most strokes are caused by blockages (usually blood clots) disrupting the brain’s

Stroke Definition: A stroke is the sudden death of the cells in a specific area of the brain caused by inadequate blood flow. Another name for it is cerebral vascular accident (CVA). A stroke is also called a brain attack. Description: A stroke occurs when an artery bursts or becomes closed when a blood clot lodges in it and blood flow is interrupted to that part of the brain. Blood circulating to that area of the brain served by the artery stops at the point of rupture‚ and the brain tissue

Stroke What is stroke? A stroke is a serious medical condition that occurs when the blood supply to part of the brain is cut off. Strokes are a medical emergency and prompt treatment is essential because the sooner a person receives treatment for a stroke‚ the less damage is likely to happen. Ischemic strokes Ischaemic strokes‚ the most common type of stroke‚ occur when blood clots block the flow of blood to the brain. Blood clots typically form in areas where the arteries have been narrowed
