The Brain is the most complex organ in the Human body. It produced our every though, Action , Memory, Feeling and Experience of the World. The parts of brain are cerebrum, Mid-Brain, Pons, medulla oblongata and cerebellum. Arterial blood supply to brain includes circulus areteriosus and its contributing arteries. It plays a vital role in maintaining a constant supply of oxygen and glucose to brain. Brain receives about 15% of the cardiac output, approximately 750 ml of blood per minutes.1 In adult, brain represents only 2% of total body weight, but consumes about 20% of the oxygen and glucose used even at rest. Typically an interruption in blood flow for 1 or 2 minutes impairs neuronal function and total deprivation of oxygen for about 4 minutes causes permanent injury. If blood entering the brain has low level of glucose, mental confusion, dizziness, convulsion and loss of consciousness may occur. The most common brain disorder is a cerebrovascular accident, also called a stroke or brain attack.2 Stroke is a term used to describe neurologic changes caused by an interruption in the blood supply to a part of the brain. Two major types of strokes are ischemic and hemorrhagic. Ischemic stroke is caused by a thrombosis or embolic blockage of blood flow to the brain. Bleeding in to the brain tissue or the subarachnoid space causes a hemorrhagic stroke. Ischemic strokes accounts for about 83% of all strokes. The remaining 17 % of strokes are haemorrhagic.
