Associations of mobility and frailty risk with wayfinding ability in aging.

= 8; 70.3% female). Worse mobility was associated with poorer memory for environmental details. This association was partially mediated by domain-specific cognition, and processing speed had the largest unique contribution. Weaker grip strength-reflecting increased frailty risk-was associated with worse navigation efficiency in locating the hidden platform during the task, and this effect was largely independent of other cognitive correlates. Mobility and frailty risk were associated with self-reported navigation strategy preference in the real world. Individual differences in visuospatial immediate recall and delayed associative recall contributed to this association, although mediation was not supported. Taken together, mobility and frailty risk were differentially associated with wayfinding deficits in aging, which was partially shared with domain-specific cognition. Continued study can explore mobility and frailty as modifiable risk factors to maintain wayfinding ability and promote independence into late life.
