MoCA量表在老年轻度血管性认知障碍患者中的应用效果评价

Analysis of neuropsychological characteristics for old patients with vascular mild cognitive impairment by MoCA scale.

目的研究轻度血管性认知障碍的神经心理学特征,为轻度血管性认知障碍的早发现、早诊断、早治疗提供科学依据。方法以2010年1月至2011年5月在我院接受治疗的74例轻度血管性认知障碍患者为研究对象,采用蒙特利尔认知评估量表(MoCA)调查患者的神经心理学特征资料,并进行各个认知领域的分析。结果 MoCA量表评估轻度血管性认知障碍患者的准确率达97.3%。年龄、文化程度和职业对MoCA得分的影响差异有具统计学意义(P<0.05)。轻度血管性认知障碍患者在延迟记忆、注意、视空间与执行能力三个认知领域的得分占各自总分的比例最低,依次为31.40%、65.17%和69.00%。结论 轻度血管性认知障碍的神经心理学特征主要表现为视空间与执行能力、注意和延迟记忆等认知领域的损害较重。MoCA量表对轻度血管性认知障碍患者的早期筛查效果较好,值得推广应用。

Objective To study the neuropsychological characteristics for old patients with vascular mild cognitive impairment （vMCI） with MoCA scale in order to provide science evidence for early discovery, diagnosis and in- tervention of vMCI. Methods The vMCI patients who accepted therapy in our hospital from January 2010 to May 2011 were surveyed by Montreal Cognitive Assessment （MoCA）. Results The accuracy rate of MoCA was 97.3%. Age, educational level and occupation significantly influenced the score of MoCA （P 〈0.05）. The score of delayed re- member, attention and visual space were the lowest percentage of their own total score, as 31.40%, 65.17% and 69.00%. Conclusion MoCA was a good tool to screen the vMCI, and it should be widely applied. In addition, the neuropsychological characteristics of vMCI were heavier damage in visual space and executive ability, attention and delayed memory and so on.
