Objectives To examine the distribution and associated predictors of 1‐year changes in the Japanese version of the Montreal Cognitive Assessment ( M o CA ‐ 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 M o CA ‐ J performance, as opposed to stable or deteriorating, while simultaneously adjusting for baseline M o CA ‐ J score and major confounders. Results Mean age was 74.0 ± 4.8; mean M o CA ‐ J score was 23.7 ± 3.6. Only 40% had stable M o CA ‐ 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 M o CA ‐ J performance deterioration. Conclusion Slower TUG and walking speed performances were independent predictors of short‐term M o CA ‐ J deterioration. Research aimed at assessing lower‐extremity performance‐based tests in MCI ‐related decision‐making is warranted.
