Abstract
OBJECTIVES
We investigated the predictors of subjective memory complaints in the community-dwelling normal elderly.
METHODS
This study was conducted as a part of Korean Longitudinal Study on Health and Aging (KLoSHA). 747 nondemented community-dwelling elderly aged 65 years or older were recruited. All participants underwent clinical evaluation for dementia and psychiatric disorder conformed to the Korean version of the Consortium to Establish a Registry for Alzheimer's Disease (CERAD-K) Clinical Assessment Battery and Korean version of Mini-International Neuropsychiatric Interview, respectively. Word list recall test, frontal assessment battery, Mini Mental Status Examination (MMSE-KC) and Korean version of Geriatric depression scale (GDS-K) were administered to evaluate episodic memory, frontal function, global cognition and depression, respectively. Subjective memory complaint was defined in two different ways: worse than one's past (SMC-P) and worse than others of one's age (SMC-O).
RESULTS
In highly educated elderly, minor depressive disorder (OR=7.23, 95% C.I.= 2.29-22.86) and frontal dysfunction (OR=2.48, 95% C.I.=1.29-4.77) significantly increased the risk of SMC-O. However, they did not influence the risk of SMC-P. In low educated elderly, both the minor depressive disorder and frontal dysfunction did not influence the risk of SMC-O as well as that of SMC-P.
CONCLUSION
SMC-O can be a sensitive subjective recognition of mild depression and/or frontal dysfunction in highly educated normal elderly.
