The reasons leading to a stroke which

When blood clots to plug the flow of a certain part of the brain blood flow, the occurrence of thrombotic stroke, and vascular occlusion of cerebral arteriosclerosis caused by the narrow, ultimately contribute to the formation of embolism, can be both in the static local blood clots, and can also be formed elsewhere and moved to a partial certain other substances, which trigger wind clots and can slow blood flow arising from, for example, heart attack, blood clots in heart wall formation, where the flow slower. Hemorrhagic stroke, the most common vulnerability stems from the brain's arteries, or ruptured artery, the artery sometimes congestive embrittlement. But more common in the hypertensive vascular tension so weakened, hemorrhagic stroke can be leakage from the arteriovenous malformation, cerebral excessive generation of angiogenesis in patients with congestive perspective. The vast majority of strokes occur in the elderly aged over 60, more women than men involved, possibly because of the high incidence of hypertension of the reason that younger people are more prone to get haemorrhagic stroke, and age are usually more susceptible to thrombotic stroke. For stroke, the main control of the risk factors are hypertension, hypercholesterolemia, not love a sedentary lifestyle, obesity, drug abuse irritation, such as amphetamines, smoking, oral contraceptives and depression. When patients showing stroke-like symptoms, neurological physicians to determine not only its symptoms, and must identify, stroke type, location and extent of brain injury, the treatment of the basis of all these circumstances, and immediately experimental screening, as timely treatment can limit nerve damage. Physicians initial screening patients, access to medical history and, if possible, the standards include retinal vascular screening examination, the heart and arteries revealed a weak voice heard abnormalities, measurement of blood pressure, pulse rate, measuring muscle tension, feelings and nerve reflex. CT or MRI scan is the most standard of diagnosis of stroke inspection.
