cerebrovascular disease include some of the most common and devastating disorders:ischemic stroke,hemorrhagic stoke,and cerebrovascular anomalies such asintracranial aneurysm and arteriovenous malformations.脑血管疾病包括一些最常见的和破坏性的疾病:缺血性中风,出血性中风,以及与脑血管有关的异常颅内的动脉瘤和动静脉畸形等。The incidence of cerebrovascular diseases increases with age,and the number of strokes is projected to increase as the elderly population grow,with a doubling in stroke deaths in the United States by 2030.脑血管疾病的发病率随着年龄的增加,而且这个数目的中风预计将增加,随着老年人口成长与中风死亡率增长一倍,到2030年在美国.Most cerebrovascular diseases are manifest by the abrupt onset of a focal neurologic deficit,as if the patient was struk by the hand of God.大多数的脑血管疾病表现有助于达到局灶性神经赤字,仿佛这个病人被“袭击者在由上帝之手”。A stroke,or cerebrovascular accident,is defined by this abrupt onset of a neurologic deficit that is attributable to a focal vascular cause.中风或脑血管意外,是定义在突然出现神经赤字,归因于灶血管疾病。Thus,the definition of srtoke is clinical,and laboratory the diagnosis.the clinical manifestations of stroke are highly variable because of the complex anatomy of the brain and its vasculature.因此,srtoke的定义是临床、实验室诊断临床表现因中风是高度可变的复杂构造的大脑及它的动作。Cerebral ischemia is caused by a reduction in blood flow that lasts longer than several seconds. 脑缺血是由于减少血液流动,持续超过几秒Neurologic symptoms are manifest within seconds because neurons lack glycogen,so energy failure is rapid.when blood flow is quickly,restored,brain tissue can recover fully and the patient is symptoms are only transient ischemic attack (TIA).Typically the neurologic signs and symptoms of a TIA last for 5 to 15min but,by definition,must last24h.if the cessation of flow lasts for more than a few minutes, infarction or death of brain tissue results.神经病学症状表现在几秒钟内因为神经元缺乏糖原,能源失败是rapid.when血流方向迅速,恢复、脑组织就能完全康复,患者症状只是短暂性脑缺血发作(TIA).Typically的神经系统的症状和体征的TIA持续5到15min。不过,根据定义,必须持续 24h.if停止流动持续超过几分钟,梗塞或者死亡的脑组织的结果。Stroke has occurred if the neurologic signs and symptoms last for 24. 如果中风发生神经系统的症状和体征持续 24岁.A generalized reduction in cerebral blood flow due to sys
