The relationship between hearing loss and depression, cognition, and dementia
Adults with hearing loss can be substantially affected by social isolation, loneliness, and depression; evidence suggests that treatment with cochlear implants can lead to improvement in these aspects of well-being and mental health. Longitudinal studies are needed to obtain further knowledge in this area.
There is an association between age-related hearing loss and cognitive/memory impairment.
Further research is required to confirm the nature of cognitive impairment in individuals with hearing loss, and its potential reversibility with treatment.
