Observational analysis shows declines in driving abilities in older adults with mild cognitive impairment, suggesting monitoring could guide interventions to maintain mobility.
MCI was associated with progressive declines in driving frequency, complexity, and spatial range, supporting naturalistic driving data as a potential unobtrusive digital biomarker for early cognitive decline. Limitations of the study include a predominantly White, highly educated sample and a lack of external validation, warranting cautious interpretation. Continuous monitoring could augment clinical assessments, inform driving safety decisions, and guide interventions to preserve mobility in aging.
