Abstract
Objectives To examine the distribution and associated predictors of 1-year changes in the Japanese version of the Montreal Cognitive Assessment (MoCA-J) in community-dwelling older adults. Design Prospective cohort study. Setting Population-based cohort study in Tokyo, Japan. Participants Individuals aged 65 to 84 (N = 496). Measurements Multinomial logistic regression analysis was performed to estimate the odds of experiencing subsequent improvement in MoCA-J performance, as opposed to stable or deteriorating, while simultaneously adjusting for baseline MoCA-J score and major confounders. Results Mean age was 74.0 ± 4.8; mean MoCA-J score was 23.7 ± 3.6. Only 40% had stable MoCA-J performance; 30% experienced deterioration and 30% improvement. Age increment, hospitalization in previous year, slower Timed Up and Go (TUG) score, and slower maximum walking speed were predictive of subsequent MoCA-J performance deterioration. Conclusion Slower TUG and walking speed performances were independent predictors of short-term MoCA-J deterioration. Research aimed at assessing lower-extremity performance-based tests in MCI-related decision-making is warranted.
