Abstract

Purpose: Women suffer from greater age-related decline in mobility than men. Cognitive dysfunction is associated with slower gait speed in older women, but whether cognitive function affects gait performance earlier in life has yet to be investigated. Thus, the objective of this study was to test the hypothesis that cognitive function will discriminate gait performance in healthy middle-aged women. Methods: Fast-pace and dual-task gait speed was measured in 30 middle-aged (30-45y) and 26 older (61-80y) women without mild cognitive impairment. Visuoperceptual ability, working memory, executive function, and learning ability were assessed using standard neuropsychological tests. Within each age group, women were divided by the median into lower and higher cognitive function groups to compare gait performance. Results: Middle-aged women with higher visuoperceptual ability had faster fast-pace (2.25 ± 0.30 vs. 1.98 ± 0.18 m/s, p≤0.01) and dual-task gait speed (2.02 ± 0.27 vs. 1.69 ±
