在一些发达国家或地区，蒙特利尔认知评估(MoCA)已被证明是筛选轻度认知障碍(MCI)和早期痴呆的简便和敏感的工具。然而，从大陆中国那里获得的中国电影协会数据却很少。在这项研究中，对8411名65岁或以上的中国社区居民(6283=认知正常[CN]，1687=MCI，441=痴呆)进行了调查。在考虑重大影响因素的基础上，建立了MoCA常模。文盲的最佳分界点为13/14，受过1至6年教育的为19/20，受过7年或7年以上教育的为24/25。在最佳阈值下，MoCA对所有认知障碍的敏感性为83.8%，对MCI的敏感性为80.5%，对痴呆的敏感性为96.9%，对CN的特异性为82.5%。这些结果表明，在最佳界值下，MOCA可以有效地筛查社区老年人的认知功能障碍。
The Montreal Cognitive Assessment (MoCA) has been proved brief and sensitive to screen for mild cognitive impairment (MCI) and early dementia in some developed countries or areas. However, little MoCA data are available from mainland China. In this study, the MoCA was applied to 8411 Chinese community dwellers aged 65 or older (6283 = cognitively normal [CN], 1687 = MCI, and 441 = dementia). The MoCA norms were established considering significant influential factors. The optimal cutoff points were 13/14 for illiterate individuals, 19/20 for individuals with 1 to 6 years of education, and 24/25 for individuals with 7 or more years of education. With the optimal cutoffs, the sensitivity of the MoCA was 83.8% for all cognitive impairments, 80.5% for MCI and 96.9% for dementia, and the specificity for identifying CN was 82.5%. These indicate that with optimal cutoffs, the MoCA is valid to screen for cognitive impairment in elderly Chinese living in communities.
