Recent research suggests that improving hearing loss with hearing aids reduces the risk for Alzheimer’s disease and dementia. In 2011, a team of Johns Hopkins medical school researchers discovered a significant association between hearing loss and the risk of developing these unwanted cognitive conditions. The worse someone’s hearing gets, the greater their risk of developing Alzheimer’s or dementia. The researchers believe their findings could have substantial implications for individuals and public health because hearing loss is treatable with hearing instruments. These findings underscore how important regular hearing tests are as part of preventative health care.
