Relationship between subjective memory complaints and objective memory impairment in a community-dwelling elderly population

Abstract

Objective: Subjective memory complaints are important as they are considered predictor of dementia. In this study, we aim to explore the association of subjective memory complaints that was measured with a questionnaire with objective memory impairment in community-dwelling elderly people. Method: In this cross-sectional study, we evaluated 100 people aged 65 or over from general population. All participants were assessed in terms of sociodemographic features, subjective memory complaints and cognitive functions. We used a sociodemographic data form that was prepared by researchers, Subjective Memory Complaints Questionnaire, Mini Mental State Examination and Controlled Oral Word Association Test. Results: We found that participants suffering from forgetfulness had higher scores of subjective memory complaints than those without forgetfulness. Participants with Mild Cognitive Impairment on the basis of Subjective Memory Complaints Questionnaire had lower scores of Mini Mental State Examination and Controlled Oral Word Association Test. As indicated by the linear regression analyses, there were associations between subjective memory complaints and Mini Mental State Examination and Controlled Oral Word Association Test. However, these associations were not significant when controlled for level of education. Discussion: Subjective memory complaints have been thought to be related with objective memory impairments and considered predictor of dementia in elderly. In previous studies, assessment of subjective memory complaints is suggested as a screener for dementia. However, third variables such as level of education should be considered when assessing people with subjective memory complaints.
