Baseline Mobility is Not Associated with Decline in Cognitive Function in Healthy Community-Dwelling Older Adults: Findings From The Irish Longitudinal Study on Ageing (TILDA).
Few studies examine the relationship between Timed Up-and-Go (TUG), a commonly used clinical test, and cognitive decline. This study examines whether TUG, usual gait speed (UGS), and dual-task gait speed (DTGS) predict decline in global cognition, executive function, processing speed, memory, and attention with follow-up of up to 5.9 years. ⋯ These mobility tasks are not sensitive predictors of cognitive decline in this high-functioning, community-dwelling sample; nonetheless, limited decline in cognitive function was observed during follow-up. Further work with longer follow-up and/or analysis of more specific and comprehensive measures associated with gait is required.
