Age related hearing impairment (ARHI, also known as presbycusis) is an important frailty marker, and could be a reversible risk factor for dementia and Alzheimer disease. Poor verbal communication and depletion of cognitive reserve might causally link ARHI to cognitive decline and frailty; hearing aids and cognitive training might, thus, provide a strategy to delay or prevent cognitive deterioration. In this Review, Panza and colleagues discuss the interplay between cognitive impairment, ARHI and frailty in older age.
