MoCA量表对短暂性脑缺血发作后认知功能障碍的评价

Application of Mo CAscale in assessing cognitive impairment in patients with transien tischemic attacks

目的:探讨MoCA量表对短暂性脑缺血发作后认知功能障碍的评价。方法:选取51例首次发病的短暂性脑缺血(TIA)患者为观察组,采用中文版MoCA认知功能评定量表进行认知功能测试,同时选取41名性别、年龄和受教育程度相匹配的正常健康人群作为对照组,比较两组患者MoCA量表测试结果。结果:TIA患者的MoCA量表总分显著低于对照,其中TIA患者的视空间与执行功能、注意、延迟记忆评分均显著低于对照组,两组比较差异有统计学意义(均P<0.01),两组的命名、语言、抽象思维及定向力评分相比较,差异均无统计学意义(P>0.05),具有可比性。结论:TIA患者存在不同程度的与额颞叶有关的认知功能损害,中文版MoCA量表可以用于评价TIA患者的认知功能障碍。

Objective To explore the assessment of Mo CAscale on cognitive impairment after transient ischemic attacks（TIA）.Method Fifty-one TIA patients were tested for cognitive function by using Montreal Cognitive Assessment（Mo CA） after onset.Another 41 health people matched with age,gender and education level were selected as the control group.The results of Mo CA test were compared between the two groups.Results The summed scores of Mo CA in patients with TIA were significantly lower than those of normal controls.The scores of vision space and executive function,attention and delayed memory in TIA patients were markedly lower than those in normal controls（P0.01）,but there was no significant difference in the scores of denomination,language,Abstract thinking and orientation between two groups（P0.05）.Conclusion TIA patients have cognition impairments related to frontal and temporal lobes at some extent,and Chinese edition Mo CA can be used to evaluate cognition impairment after TIA.
