Cochlear Implantation improves cognitive function among elderly with severe hearing loss
Researchers have found in a new study that Cochlear Implantation improves cognitive function among elderly with severe hearing loss.
The new study has been published in the JAMA Otolaryngology
Given the rapidly rising dementia incidence, management of modifiable risk factors, such as hearing loss, is vital. 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.
A study was done to evaluate the cognitive functioning of older adults with severe hearing loss at risk for mild cognitive impairment (MCI) before and after cochlear implantation.
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. A consecutive sample of older adults with severe hearing loss eligible for cochlear implantation was included. All participants obtained a Repeatable Battery for the Assessment of Neuropsychological Status for hearing-impaired patients (RBANS-H) total score indicative of MCI preoperatively. Participants were assessed before cochlear implant activation and 12 months after cochlear implant activation. The intervention consisted of cochlear implantation. The primary outcome measure was cognition, measured by the RBANS-H.
