Physical Fitness and Cognitive Function in Persons with Dementia and their Caregiver.

A cross-sectional design investigated the physical attributes of 15 dyads of people with dementia and their caregivers. Physical and cognitive markers determined deviations from clinical thresholds for loss of functional independence, where 100% of participants performed below criterion-referenced threshold values for aerobic endurance. Walking distance for people with dementia was associated with bath/shower activity (p =.007), transfers (p <.001), and mobility (p =.013). Less distance walked was associated with more assistance with self-care tasks. Physical deficits associated with low aerobic endurance and lower body strength compromised independence, placing dyads at risk for falls and mobility-related health issues. [ABSTRACT FROM AUTHOR]
