轻微认知功能损害快速识别方法的初步研究

Research on Identify Method of Mild Cognitive Impairment

目的 :分析轻微认知功能损害快速识别方法。方法 :以记忆减退为主诉的 5 5岁以上老人 15 0名 ,接受韦氏智力量表中文修订 (WAIS -RC)和韦氏记忆量表中文修订版 (WMS -RC)评估。其中智商 (IQ)和记忆商 (MQ)均在 85以上 6 3名 ,作为正常老人组 ;IQ在 85以上、MQ为 70～ 84的 33名 ,作为MCI - 1组 ;IQ在 85以上、MQ为 5 5～ 6 9的 2 5名 ,作为MCI - 2组 ;IQ和MQ均在 85以下、临床表现符合DSM -Ⅳ有关阿尔茨海默病的诊断标准的有 2 9例。结果 :图片记忆和心智B得分在 2个MCI组与正常老人组间最具鉴别力。对记忆轻度受损 (MCI -1组 )有重要识别作用的还有视觉再生记忆 ,对记忆较重受损 (MCI - 2组 )有重要识别作用的还有触觉记忆、理解记忆和联想记忆。结论 :图片短时记忆和心智B可以作为临床医师筛选轻微认知功能损害 (MCI)的有效工具。

Objective:To analyze identify method of mild cognitive impairment. Methods:The Wechsler Adult Intelligence Scale-Chinese Revised (WAIS-RC) and Wechsler Memory Scale-Chinese Revised (WMS-RC) were examined in 150 patients with memory complaints. 63 individuals whose intelligence quotient (IQ) and memory quotient (MQ) over 85 were designated as normal elderly group;and 33 individuals whose IQ scores over 85 and MQ score between 70 and 84 as mild cognitive impairment(MCI-1) group; and 25 individuals whose IQ scores over 85 and MQ scores between 55 and 69 as MCI-2 group; 29 individuals whose IQ scores and MQ scores less than 85 and conformed with DSM-Ⅳ as Alzheimer disease group.Results: Picture short memory and mental control (B)showed the highest identification between the 2 MCI groups and normal elderly group. Besides, visual reproduction played an important role in mild memory decline (MCI-1) group. Tactile memory, logical memory and associated learning played an important role in moderate memory decline (MCI-2) group.Conclusion: Picture short memory and mental control (B) contribute to identify MCI speedily and effectively.
