摘　　要：脑动脉狭窄不仅是缺血性卒中的常见原因,也是认知功能下降的独立危险因素。相较于后循环系统,前循环系统狭窄发生率高,对认知的影响更广泛。脑侧支循环是指颅内外潜在的或新生的血管吻合,在脑供血不足时起代偿作用,对缺血性卒中的发生发展起重要作用。目前,脑动脉狭窄后侧支循环建立及狭窄发生后侧支循环建立对认知影响的研究较少。该文就无症状前循环脑动脉严重狭窄及侧支循环建立对认知功能的研究进展进行综述。Cerebral artery stenosis is not only a common cause of ischemic stroke,but also an independ-ent risk factor for cognitive decline.Compared with the posterior circulatory system,the anterior circulatory system has a higher incidence of stenosis and has a wider impact on cognition.Cerebral collateral circulation refers to the potential or new anastomosis of intracranial and extracranial vessels,which plays an important role in the occurrence and development of ischemic stroke and plays a compensatory role in the insufficient cerebral blood supply.At present,there are few studies on the cognitive effects of the establishment of collat-eral circulation after cerebral artery stenosis and the establishment of collateral circulation after stenosis.This article reviews the research progress on cognitive function of severe asymptomatic anterior circulation cerebral artery stenosis and establishment of collateral circulation.
