This feasibility investigation for the Fujiwarakyo study, a cohort studyfocusing on health-related quality of life among the healthy elderly was performed for 5days in February, 2007. Mental status, one of the investigative components, was evaluatedby Mini-Mental State Examination (MMSE), word recall test (one of the subtests ofAlzheimer's Disease Assessment Scale-cognitive component-Japanese version: ADAS-Jco9.), and Geriatric Depression Scale, short form (GDS15). Participants consisted of 74males (mean age: 75.2 y.o.) and 67 females (74.3 y.o.). MMSE scores were distributed from19 to 30 ; 20 cases (14.2%) were lower than 24 points (dementia range). Mild cognitiveimpairment (MCI) was found in 9 cases (6.4%), in whom MMSE scores were more than 24points and less than 1.5 standard deviation (SD) in the word recall test. The meannumber of correct answers in the word recall test was 6.0, and they were positivelycorrelated with MMSE scores (R=0.41, P<0.001). GDS15 scores were 2.4 ± 2.0 (mean ±SD) and the healthy elderly with depressive sylnptoms (≧6 points) were 18 cases (12.8%).Scores of MMSE and GDS15 are reported to be affected by gender or education. Toexclude these effects, the Fuji'warakyo study to be performed in future is going toconsider factors such as gender and education for evaluation dementia, MCI and depressive symptoms.
