Analysis on the everyday memory characteristics and life quality of people with subjective memory complaints

Abstract

Objective To investigate the characteristics of everyday memory of adults with subjective memory complaints (SMC), and probe into the correlation between everyday memory function and life quality. Methods Through convenience sampling, 150 adults with SMC were face-to-face interviewed by an investigator, with demographic characteristics collected, and the cognition function, everyday memory function and life quality were also assessed during the interview. Results Among the 150 adults with SMC, the impairment rate of everyday memory function reached 96%, and the median score of RBMT-II was 16.00 (inter-quartile range 6.00), indicating a low level of everyday memory function, with theNameandDelayed recall Storyitems having lower scores. All participants were divided into two groups according to cognitive status, with 67 (44.70%) adults having normal cognitive function and 83 (55.30%) impaired cognitive function. After comparison, significant differences were found in the total score of RBMT-II and scores ofFaces recognitionandDelayed recall Storybetween the two groups (P<0.05). In all dimensions of SF-36, the median score of general health dimension for the 150 adults was 55.00 (inter-quartile range 31.25). The Spearman rank correlation analysis showed that the scores of several dimensions in RBMT-II were positively correlated with the scores of several dimensions in SF-36 (P<0.05). Conclusion Everyday memory function of people with SMC was positively correlated with their life quality. Key words: Subjective memory complaint; Life quality; Community
