Project Description

Presbycusis, or age-related hearing loss, affects ~25% percent of the over-60 population, and often leads to isolation and depression; and a growing body of evidence suggests that there is a strong association between hearing loss and cognitive impairment. Preliminary studies suggest that cochlear implantation in older adults may be protective against cognitive decline, and provide improvement in cognitive abilities. This illustration portrays an older adult with presbycusis who has been implanted.  Patients learn how the cochlear implant integrates into the anatomy of the inner ear, and see that several brain areas are stimulated. The inset on the right is a zoomed in view of the implanted cochlea.
