Mosnier I, et al. - In this prospective observational longitudinal study performed at 10 academic medical centers, researchers assessed long-term cognitive status and function after cochlear implantation in profoundly deaf individuals aged 65 and older (N=70). A high prevalence of mild cognitive impairment (MCI) was reported in older adults with profound hearing loss. Yet, rate of progression to dementia was low. In some individuals with MCI at baseline, improved cognitive function was evident. Cochlear implantation should be strongly considered in profoundly deaf individuals, even those with MCI, who may have a specific subtype of MCI, with a possible positive impact of hearing rehabilitation on neurocognitive functioning.
