摘要: 目的 探讨脑白质病变(WML)并发不同程度认知障碍所致的执行功能障碍与胆碱能通路损伤之间的关系。方法 连续纳入2016年3月至2017年12月符合入组标准的患者115例,收集其人口学资料和血管病危险因素;经头颅MRI T2加权筛选出WML患者80例,根据蒙特利尔认知评估(MoCA)及临床痴呆评定(CDR)结果,将WML患者分为WML伴认知正常(CN)组41例、WML伴非痴呆型血管性认知障碍(VCIND)组21例和WML伴痴呆(VaD)组18例;其余35例无WML且认知正常患者为对照组。采用胆碱能通路高信号量表(CHIPS)对患者MRI下脑白质损伤情况进行评定;采用Stroop色词干扰测验、数字连线测验、数字符号模式测验、言语流畅性测验对并发认知障碍的患者进行执行功能评定;对CHIPS评分与执行功能评分进行相关性分析。结果 4组间年龄、性别、受教育程度、血管病危险因素无显著性差异(P>0.05),MoCA和CHIPS评分有非常高度显著性差异(F>25.781, P<0.001),VaD组MoCA总分最低(P<0.01),CHIPS各项评分均最高(P<0.001)。VCIND组和VaD组全脑和左半球CHIPS评分与各项执行功能评分呈负相关(P<0.05),右半球CHIPS评分与部分执行功能评分呈负相关(P<0.05)。结论 WML并发认知障碍时,胆碱能通路损伤与执行功能下降关系密切,左侧大脑半球胆碱能通路损伤影响更为明显。

Abstract: Objective To investigate the relationship between cholinergic pathway damage and the executive dysfunction of patients with different degrees of cognitive impairment caused by cerebral white matter lesions (WML). Methods From March, 2016 to December, 2017, 115 patients were recruited, whose characteristics, such as age, gender, education, and history of hypertension, diabetes and stroke were recorded. According to the T2-weighted MRI, 80 patients were defined as WML. WML patients were divided into cognitively normal (CN) group (n=41), vascular cognitive impairment of none dementia (VCIND) group (n=21) and vascular dementia (VaD) group (n=18) according to the result of Montreal Cognitive Assessment (MoCA) and Clinical Dementia Rating (CDR). Other 35 cases without WML and cognitive impairment were as control group. WML under MRI were evaluated with Cholinergic Pathways Hyperintensities Scale (CHIPS). All the WML patients were assessed with Stroop Color-Word Test, Trail Making Test, Symbol Digital Modalities Test, and Verbal Fluence Test. The correlation between the scores of CHIPS and the executive tests were analysed. Results There was no significant difference in age, gender, level of education, and cardiovascular disease risk factors among four groups (P>0.05), but there were significant differences in scores of MoCA and CHIPS (F>25.781, P<0.001), while the score of MoCA was the least (P<0.01) and the scores of CHIPS were the most in VaD group (P<0.001). The CHIPS scores of left and bilateral hemisphere negatively correlated with all the scores of executive tests (P<0.05), while that of the right hemisphere just correlated with the scores of some executive tests (P<0.05).Conclusion For cognitive impairment after WML, cholinergic pathway damage may relate with the executive function impairment, especially the damage in left cerebral hemisphere.
