项目摘要

Background : Little is known regarding the normative levels of cognitive function among the oldest old. Methods : The sample included 391 community-dwelling elderly, in which 293 elderly with no disability in Activities of Daily Living (ADL) and minimal dependency in Instrumental ADL (IADL). We examined 1) domain-specific cognitive functions, 2) the nature and frequency of leisure activities, comparing the oldest old vs. younger age groups. Cognitive tests examined and their specific domains were as follow ; MMSE (general cognitive function), Word list immediate recall (learning/acquisition) from ADAS, Word list delayed recall (memory) from the ADAS, Block Designs (visuo-spatial ability) from the WAIS-R, Trail-making test A (psychomotor speed), Trail-making test B (executive function), Word Fluency Categories : Animals and Vegetables (language). Results : The oldest old (age 85 and older) showed significantly lower cognitive function in all cognitive domains compared with the youngest old (age 65-74) and old old (age 75-84). In addition to the age, educational level was also an important determinant of cognitive function. Conclusion& We showed domain specific cognitive function ranging from young old to oldest old and its dependency on age and educational level. These data will be important to detect early stage dementia and to support elderly in the community.

背景：关于高龄老人认知功能的标准水平知之甚少。研究方法：样本包括391名社区老年人，其中293名日常生活活动能力（ADL）无残疾，工具性ADL（IADL）依赖性最低。我们检查了1）特定领域的认知功能，2）休闲活动的性质和频率，比较了最年长的老年人与年轻人。检查的认知测试及其具体领域如下：MMSE（一般认知功能）、ADAS的词表即时回忆（学习/获得）、ADAS的词表延迟回忆（记忆）、WAIS-R的区组设计（视觉空间能力）、线索制作测试A（心理速度）、线索制作测试B（执行功能）、词汇流畅性类别：动物和蔬菜（语言）。结果如下：与最年轻的老年人（65-74岁）和老年人（75-84岁）相比，最年长的老年人（85岁及以上）在所有认知领域的认知功能显着降低。除年龄外，受教育程度也是认知功能的重要决定因素。结论：从青年到老年，认知功能呈现出领域特异性，并与年龄和教育水平相关。这些数据对于检测早期痴呆症和支持社区老年人非常重要。
