Evaluation of Cognitive Functioning Before and After Cochlear Implantation in Adults Aged 55 Years and Older at Risk for Mild Cognitive Impairment

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.
