A stroke happens when blood flow to a part of the brain stops. A stroke is sometimes called a 'brain attack'. If blood flow is stopped for longer than a few seconds, the brain cannot get blood and oxygen. Brain cells can die, causing permanent damage. There are two major types of stroke: ischemic stroke and hemorrhagic stroke. Ischemic stroke occurs when a blood vessel that supplies blood to the brain is blocked by a blood clot. This may happen in two ways: A clot may form in an artery that is already very narrow. This is called a thrombotic stroke; A clot may break off from another place in the blood vessels of the brain, or from some other part of the body, and travel up to the brain. This is called cerebral embolism, or an embolic stroke; Ischemic strokes may be caused by clogged arteries. Fat, cholesterol, and other substances collect on the artery walls, forming a sticky substance called plaque. Ischemic Stroke is a leading cause of morbidity and mortality. Approximately 85% of strokes are ischemic, caused by vascular occlusion. A clinical emergency: timely diagnosis, triage, and intervention can improve outcome. Care of patients in dedicated stroke units results in improved survival and function. Intravenous tissue plasminogen activator is given within 4.5 hours of stroke onset. Intra-arterial reperfusion therapies, using either intra-arterial thrombolysis or clot retrieval devices, are used by experienced centers in select cases up to 8 hours from symptom onset. The symptoms of stroke depend on what part of the brain is damaged. In some cases, a person may not know that he or she has had a stroke. Symptoms usually develop suddenly and without warning. Or, symptoms may occur on and off for the first day or two. Symptoms are usually most severe when the stroke first happens, but they may slowly get worse.
