Episodic memory is vulnerable to deterioration in people suffering from Alzheimer's disease. Currently, the Logical Memory (LM) subtest of the Wechsler Memory Scale-Revised (WMS-R) is used internationally as an operational definition to identify people with mild cognitive impairment (MCI). However, the Japanese version of the LM has not been adequately normalized for old-old people. Therefore, norms of the LM for people aged 75 years and over are required, and the effects of sex, age and education on performance were evaluated.
A total of 50 (27 female and 23 male) participants without a history of dementia and symptomatic stroke events recruited from the community and hospital populations were investigated using the Mini-Mental State Examination, the LM and some interference tasks.
The mean scores (standard deviations) of the sample were 15.5 (5.4) on LM-I and 9.9 (6.6) on LM-II. The distributions of the LM-I and -II scores satisfied the normality assumption. The LM-I and LM-II scores correlated with age and the LM-I score correlated with educational background.
For the Japanese version of the LM, the means, standard deviations and distribution features of the old-old sample are presented. Although the normal sample was chosen to closely match the demographic profile of the Japanese population, the present sample might have had a higher educational background than the age-matched population, especially the males. Further study is required to standardize the Japanese version of the LM subtest for each 5-year interval for latter-stage elderly people.
阿尔茨海默病患者的情节记忆容易受损。目前，韦氏记忆量表修订版（WMS-R）的逻辑记忆（LM）子测验被国际上用作识别轻度认知障碍（MCI）患者的操作定义。然而，LM 的日语版尚未对高龄老人进行充分的标准化。因此，需要制定适用于 75 岁及以上人群的 LM 常模，并评估性别、年龄和教育对表现的影响。
从社区和医院人群中招募了 50 名（27 名女性和 23 名男性）无痴呆和有症状中风史的参与者，使用简易精神状态检查、LM 和一些干扰任务对其进行了调查。
样本的 LM-I 和 LM-II 的平均得分（标准差）分别为 15.5（5.4）和 9.9（6.6）。LM-I 和 -II 得分的分布符合正态性假设。LM-I 和 LM-II 得分与年龄相关，LM-I 得分与教育背景相关。
对于 LM 的日语版，呈现了高龄老人样本的均值、标准差和分布特征。尽管正常样本是根据日本人口的人口统计学特征选择的，但与年龄匹配的人群相比，本样本的受教育程度可能更高，尤其是男性。需要进一步的研究来为后期老年人的每个 5 年间隔标准化 LM 子测验。
