Ray J, et al. - Authors gauged the link between age-related hearing impairment (ARHI) and cognitive decline using a cohort of elderly individuals from the United Kingdom and gauged untreated hearing loss and social isolation as potential explanations for the observed link. Nonetheless, a link between the hearing loss and cognition was seen, untreated hearing loss drives the association. For those who have an untreated hearing loss, social isolation is a mediating factor in the link. Early rehabilitation and increased opportunistic screening for the elderly may prevent cognitive decline associated with ARHI.
