Abstract:

In recent years, there has been a gradual increase in the incidence of carotid artery stenosis. The relationship between cognitive function and carotid artery stenosis has always been an area of interest. Numerous studies have demonstrated that symptomatic carotid stenosis (SCS) leads to cognitive impairment. However, the impact of asymptomatic carotid stenosis (ACS) on cognitive function and its extent are still inconclusively determined. Possible mechanisms include cerebral hypoperfusion, cerebral microembolism, and cerebral white matter hyperintensities. Definitive evidence regarding whether carotid revascularization can improve cognitive impairment caused by carotid artery stenosis is still lacking. Early detection and proactive intervention before the onset of significant symptoms in patients with carotid artery stenosis can prevent cognitive decline, thereby benefiting patient prognosis. Based on an extensive review of domestic and foreign literature sources, this article reviews the association between carotid artery stenosis and cognitive function as well as its pathogenesis and explores the impact of ACS on cognitive function along with potential improvements through carotid revascularization.

摘要:

近年来颈动脉狭窄的发病率逐步增高,认知功能和颈动脉狭窄之间的关系一直受到人们的关注。较多研究表明,症状性颈动脉狭窄(symptomatic carotid stenosis, SCS)可引起认知功能障碍。然而,无症状性颈动脉狭窄(asymptomatic carotid stenosis, ACS)对认知功能的影响及影响程度目前尚未有明确的结论,可能的发病机制包括脑低灌注、脑微栓塞和脑白质高信号等,颈动脉血运重建能否改善颈动脉狭窄导致的认知功能障碍也尚未得出确切的结论。在颈动脉狭窄患者出现明显的症状前尽早发现并积极干预,能够避免认知功能下降并改善患者的预后。本文从颈动脉狭窄和认知功能之间的关系、发病机制和颈动脉血运重建等方面检索了国内外相关文献,重点从ACS对认知功能的影响和颈动脉血运重建对认知功能的改善方面进行综述。
