Cochlear implantation was associated with an improvement of overall cognitive functioning 12 months after activation (median percentile, 5 vs 12 difference, 7 ). Results A total of 21 older adult cochlear implant candidates were included in the analysis (mean age, 72 years 13 men). Main Outcome and Measure The primary outcome measure was cognition, measured by the RBANS-H. Intervention The intervention consisted of cochlear implantation. Participants were assessed before cochlear implant activation and 12 months after cochlear implant activation. All participants obtained a Repeatable Battery for the Assessment of Neuropsychological Status for hearing-impaired patients (RBANS-H) total score indicative of MCI preoperatively. A consecutive sample of older adults with severe hearing loss eligible for cochlear implantation was included. Objective To evaluate the cognitive functioning of older adults with severe hearing loss at risk for mild cognitive impairment (MCI) before and after cochlear implantation.ĭesign, Setting, and Participants This prospective, longitudinal cohort study performed at a single center reports data obtained over a 6-year period (April 2015 to September 2021) of an ongoing prospective, longitudinal cohort study on cochlear implant outcomes in older adults. Multiple studies have demonstrated an improvement of cognitive functioning in older adults with severe hearing loss after cochlear implantation however, few of these studies, to the authors’ knowledge, specifically analyzed participants achieving poor cognitive results preoperatively. Importance Given the rapidly rising dementia incidence, management of modifiable risk factors, such as hearing loss, is vital.
