Description
Louise Heyzer and colleagues ask which kinds of frailty make walking while thinking so costly for older adults. Dual-task cost, the slowdown when mind and legs work together, signals vulnerability. Their 2026 Singapore study examines two hundred eighty-one community dwellers across physical, social, and oral frailty.
Participants walked while counting backward or naming animals, taxing two mental systems. Frontal executive function, measured by a bedside battery, predicted cost in both tasks most strongly. Social and oral frailty seemed relevant to the arithmetic task until cognition entered the model, where their effects faded. Sharpening executive function, they propose, is the promising intervention target.
