Posterior Circulation and Cognitive Dysfunction

doi:10.3969/j.issn.1673-5765.2017.07.021

Abstract

Abstract:

In contrast with the traditional view that the posterior circulation had no impact on cognitive function, recent studies had shown that posterior circulation stroke could also cause different degrees of cognitive dysfunction. Recent studies had revealed that the cerebellum may be involved in the regulation of cognition and emotion. The brainstem stroke mainly led to the executive function and attention disorders. The thalamus stroke usually caused a wide range of neuropsychological change. The occipital lobe stroke usually accompanied with other posterior cerebral artery area lesions, and played a role in the formation of vascular dementia. This paper is to review research progress of association between cognitive dysfunction and posterior circulation.

Key words: Posterior circulation stroke; Cognitive dysfunction; Emotional disorders; Review; Pathophysiological mechanism

摘要：

传统观点认为，后循环区域不参与认知功能的形成，然而近期的研究显示后循环区域卒中也会引起不同程度的认知功能障碍：小脑可参与认知和情感的调节；脑干病变主要表现为执行功能和注意力的障碍；丘脑病变可引起广泛的神经心理学改变；枕叶卒中通常伴随大脑后动脉供血区域的病灶，在血管性痴呆的形成中起一定作用。本文就后循环区域与认知功能障碍的关系研究进展作一综述。
