Abstract

Objectives: The present study was to examine the differences in objective memory and cognitive function between groups by classifying the groups according memory decline and depression. Methods/Statistical Analysis: One hundred and five subjects of older adult group who agreed to participate in this study were selected. One-on-one interviews were conducted using a questionnaire on subjective memory decline, depression and objective memory by researchers. Data were analyzing with ANOVA and post-hoc test with the SPSS 22. Findings: The subjects were divided into 4 groups based on the presence absence of subjective memory decline and depression. The group with subjective memory decline and depression had statistically significantly lower scores in immediate recall, delayed recall and verbal fluency than the normal group. The group with depression only had a significantly higher mean for verbal fluency than the group with both subjective memory decline and depression. The normal group had a significantly higher mean for delayed recall than the group with subjective memory decline. There was no difference between the groups in the total MMSE-K1 score measuring the relatively-generalized cognitive function and MMSE-K1 recall measuring among MMSE-K1 sub-areas. In the presence of subjective memory decline, it is important to consider depression. If depression is involved in subjective memory decline, there were notable differences in the subjective memory compared with normal persons. Improvements/Applications: In this study, only depression was considered among emotional problems and although there are many reports indicating that anxiety may affect memory, the association between anxiety and memory was not considered.
