摘要:

“双综合征假说”可解释帕金森病认知障碍的异质性,大脑前部系统和后部系统是独立的,但部分重叠;即作用于前脑的多巴胺能系统负责执行功能、工作记忆和计划,而作用于后脑的胆碱能系统负责语义流畅性和视觉空间功能。多巴胺能/胆碱能图像以及功能性神经图像证据揭示了小脑与参与帕金森病认知过程。有证据表明,小脑同时接受多巴胺能和胆碱能投射。然而,这2种神经递质系统是否与认知功能有关尚不清楚,且小脑在帕金森病认知障碍中的作用尚不清楚。因此,此次综述总结了小脑多巴胺能和胆碱能投射及其与认知的关系,并从功能性神经图像证据中探索小脑在认知障碍帕金森病中的作用,其结果有助于理解小脑在帕金森病认知障碍机制中的作用。

Abstract: The dichotomized brain system is a concept that was generalized from the ‘dual syndrome hypothesis’ to explain the heterogeneity of cognitive impairment, in which anterior and posterior brain systems are independent but partially overlap. The dopaminergic system acts on the anterior brain and is responsible for executive function, working memory, and planning. In contrast, the cholinergic system acts on the posterior brain and is responsible for semantic fluency and visuospatial function. Evidence from dopaminergic/cholinergic imaging or functional neuroimaging has shed significant insight relating to the involvement of the cerebellum in the cognitive process of patients with Parkinson’s disease. Previous research has reported evidence that the cerebellum receives both dopaminergic and cholinergic projections. However, whether these two neurotransmitter systems are associated with cognitive function has yet to be fully elucidated. Furthermore, the precise role of the cerebellum in patients with Parkinson’s disease and cognitive impairment remains unclear. Therefore, in this review, we summarize the cerebellar dopaminergic and cholinergic projections and their relationships with cognition, as reported by previous studies, and investigated the role of the cerebellum in patients with Parkinson’s disease and cognitive impairment, as determined by functional neuroimaging. Our findings will help us to understand the role of the cerebellum in the mechanisms underlying cognitive impairment in Parkinson’s disease.
