title: One-Year Change in the Japanese Version of the Montreal Cognitive Assessment Performance and Related Predictors in Community-Dwelling Older Adults.
abstract: OBJECTIVE
  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.
  
  
  METHODS
  Prospective cohort study.
  
  
  METHODS
  Population-based cohort study in Tokyo, Japan.
  
  
  METHODS
  Individuals aged 65 to 84 (N = 496).
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  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.
