Seniors with hearing loss are significantly more likely to develop dementia

A study completed by Johns-Hopkins National Institute on Aging found that seniors with hearing loss are significantly more likely to develop dementia. This may be due to a common pathology that underlie both hearing loss and dementia or the strain of decoding sounds over the years may overwhelm the brains of people with hearing loss. Also, hearing loss often leads to social isolation which is a known risk factor for dementia. Interventions like hearing aids may delay or prevent the onset of dementia.
