Hearing Loss and Dementia
According to a study done by the Johns Hopkins School of Medicine, seniors with hearing loss are significantly more likely to develop dementia than those who retain their hearing. Researchers proposed that the strain of decoding sounds over the years may overwhelm the brains of people with hearing loss, in turn leaving them more vulnerable to dementia. Hearing loss also can lead to isolation, which is a leading factor in the formation of dementia and other cognitive disorders.
These findings could lead to new ways to combat dementia, a condition that affects millions of people worldwide and carries heavy societal burdens. Scientists report that their finding may offer a new starting point for interventions — even as simple as hearing aids — that could delay or prevent dementia by improving patients’ hearing. In other words, a simple hearing aid could delay or prevent dementia by improving patients’ hearing.
