Executive function, memory, and gait speed decline in well-functioning older adults.
BACKGROUND In community-dwelling older adults , global cognitive function predicts longitudinal gait speed decline . Few prospect i ve studies have evaluated whether specific executive cognitive deficits in aging may account for gait slowing over time . METHODS Multiple cognitive tasks were administered at baseline in 909 participants in the Health , Aging , and Body Composition Study Cognitive Vitality Sub study ( mean age 75.2 ± 2.8 years , 50.6 % women , 48.4 % black ) . Usual gait speed ( m/s ) over 20 minutes was assessed at baseline and over a 5-year follow-up . RESULTS Poorer performance in each cognitive task was cross-sectionally associated with slower gait independent of demographic and health characteristics . In longitudinal analyses , each 1 SD poorer performance in global function , verbal memory , and executive function was associated with 0.003 - 0.004 m/s greater gait speed decline per year ( p = .03-.05 ) after adjustment for baseline gait speed , demographic , and health characteristics . CONCLUSIONS In this well-functioning cohort , several cognitive tasks were associated with gait speed cross-sectionally and predicted longitudinal gait speed decline . These data are consistent with a shared pathology underlying cognitive and motor declines but do not suggest that specific executive cognitive deficits account for slowing of usual gait in aging
