Abstract
|
|
|
Hearing loss is the third most common chronic health condition faced by older adults. Recently,a number of studies have demonstrated a significant association between hearing impairmentand cognitive decline. However, the underlying explanatory mechanism of this relationhas yet to be established. Given the relation between hearing loss and cognitive decline, researchershave been interested in the effect of restoring hearing ability on cognitive functionsin older adults. One intervention option for management of the most severe to profound hearingloss in older adults is cochlear implantation (CI). We performed a review to assess the currentstatus of the literature on the potential influence of CI on cognition in the older adults.
Hearing rehabilitation through CI in elderly patients results in improvements in speech perceptionand cognitive function and lowers the progression to dementia. Further well-designedstudies with long follow-up are needed to verify whether CI influences cognition in olderadults.
