![]() ![]() It is therefore not clear whether cochlear implantation or cochlear implantation combined with post-operative auditory rehabilitation has the potential to improve cognition in adults following surgery. Moreover, only two studies reported that participants completed post-operative auditory rehabilitation, despite clinical guidelines recommending auditory rehabilitation for successful use and adjustment to a new cochlear implant. However, all these studies were limited by methodological biases that undermined reliable interpretation of results. Among the six included, five studies reported improved cognition following cochlear implantation. auditory training) is now a common and safe treatment for restoring speech and sound perception in people with severe to profound hearing loss, whereas the benefits of a cochlear implant combined with auditory training for improving impaired cognitive function (potentially) associated hearing loss are less clear.Ī recent systematic review evaluated studies reporting the effects of cochlear implantation on cognitive function in adults. A cochlear implant combined with post-operative auditory rehabilitation (i.e. Hearing loss is associated with cognitive decline and has been identified as the largest contributing, but modifiable, mid-life risk factor of dementia. Registered on April 23 2019.Īpproximately 2% of the world’s population live with severe to profound hearing loss, based on the prevalence in the USA this estimate is expected to rise with the world’s ageing population. Trial registrationĪustralian New Zealand Clinical Trials Registry ACTRN12619000609156. We anticipate that our findings will have implications for clinical practice in the treatment of adult cochlear implant recipients. The results of this trial will clarify whether the auditory training combined with cognitive training will improve cognition, sound and speech perception, mood, and quality of life outcomes in adult cochlear implant recipients. Participants 18 years or older who meet the clinical criteria for a cochlear implant will be recruited into the study. placebo) computerised cognitive training. It will determine whether auditory training combined with adaptive computerised cognitive training will elicit greater improvement in cognition, sound and speech perception, mood, and quality of life outcomes in adult cochlear implant recipients, when compared to auditory training combined with non-adaptive (i.e. This study will be conducted as a single-blind, head-to-head, randomised controlled trial (RCT). This study aims to determine if completing at-home computer-based brain training activities improve memory and thinking skills in adults following their first cochlear implant. There is an urgent need to develop new therapies to improve cognitive function in adults following cochlear implant surgery.
