Abstract

Background and Purpose: Mild cognitive impairment (MCI) is a predictor of future age-related dementia. We herein investigated associations of MCI with higher-level functional capacities, as well as with subjective difficulty regarding these functions, in community-dwelling older people, to identify a simple method for early MCI detection.

Method: We administered a test battery to 118 community-dwelling older people living in an urban area. The battery consisted of three tests;the Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC), the Touch Panel-type Dementia Assessment Scale (TDAS), and the Geriatric Depression Scale-15. We then excluded participants with possible dementia or depression symptoms, and divided the remainder (n = 67) into an MCI group (n = 16) and a non-MCI group (n = 51), according to TDAS performance.

Results: Logistic regression analysis with the MCI and non-MCI groups as dependent variables indicated that TMIG-IC was a significant variable. Male sex and the perception that preparing meals and filling out pension forms had become more difficult were significantly associated with MCI, each independently increasing the probability of MCI.

Conclusions: Subjective difficulty with higher-level functions and impairment in higher-level functional capacity may serve as indices for mass screening for MCI.
