Abstract:Objective To analyze the relative important factors affecting cognitive change with aging by longitudinal observation. Methods 1 227 community lived elderly and presenile subjects aged 55 and over were tested with short mental test of Mini Mental State Examination (MMSE) both in 1992 and 1997.Other informations about demographic, living, and health condition of the subjects were collected in 1992 and analyzed as potential predictors. Results Among the cognitively intact subjects 24 4% decreased more than 2 points in the 5 year interval on their MMSE achievement. Multivariate analysis showed that those subjects who scored around cutoff points tended to decline further. Other factors which predict deterioration in MMSE included demographic characters as age, educational attainment, and residential area. The health related factors were less important; among these the level of activity of daily living (ADL) in baseline time was a significant predictor, together with the onset of stroke in recent five years. Further observation stratified by age verified that the factors impacting cognitive change among the young, old or very old subjects were somehow dissimilar. Conclusions Important determinants on cognitive decline are age, education and residential area. Failure in physical function and history of cerebrovascular diseases are also predictors of cognitive change, but their impact are weaker than the demographic factors mentioned above.
