Analysis of cognitive domains among community-dwelling elders with normal cognitive function

Abstract

Objective To assess the characteristics of the community-dwelling elderly through a variety of objective evaluation and subjective evaluation tools and provide basis for cognitive function intervention in the community-dwelling elderly. Methods This study evaluated the global cognitive function, memory, executive function and attention and subjective memory feeling of 74 community-dwelling healthy elderly in Beijing. Results The study included 74 community-dwelling healthy elderly.The score of overall cognitive function was (27.28±1.30) points. Less than 80% of participator did not acquire the total score in abstract, language, visual space and executive function. And only 9.8% acquired the total score in the delayed memory.The average score of the memory satisfaction questionnaire was (38.28±9.40) points.In addition, there was no significant correlation between the scores of memory satisfaction of the elderly and the scores of cognitive function scale(r=0.038, P>0.05). The community elderly with normal general cognitive function also showed a relative decline in various cognitive areas, especially in delayed memory. In addition, there was no significant correlation between subjective memory perception and cognitive function scale (r=-0.116-0.157, P > 0.05). Conclusions The community-dwelling elderly with normal global cognitive function have cognitive decline in some cognitive function domains. And the cognitive function training needs to be carried out in community. There is no relationship between subjective memory assessment and objective cognitive function. More researches about the relationship between subjective memory assessment and objective cognitive function should be carried out in the future.
