HOW DO WE HEAR? Approximately 30% of individuals aged 65 and older have some degree of hearing loss, with estimates ranging from 70% to 90% of those aged 85 and older. There is evidence that older adults with hearing loss have poorer cognitive performance. Two earlier studies showed an association between hearing loss and cognitive decline over 6 years of follow-up. ln particular, the Health, Aging and Body Composition (Health ABC) Study, conducted in a sample of 1,984 communitydwelling individuals aged 70 to 79 showed that hearing loss measured using audiometric testing was independently associated with accelerated cognitive decline and incident cognitive impairment during the 6 years of follow up. In a new study of 137 older adults with major hearing loss, 1 ,139 with moderate problems, and 2,394 with no hearing trouble, hearing loss was significantly associated with greater cognitive decline scores at the start of the study and during a 25- year follow-up period. Participants with hearing loss, but not those with hearing loss who used hearing aids, had greater declines in cognitive function during follow up compared with controls.
