According to the Lancet Commission Report on Dementia Prevention, the risk of dementia can be cut by one third by treating hearing loss. The report by the leading medical journal assessed the potentially modifiable risk factors for dementia that can be addressed as preventative interventions. The report recommends wearing hearing aids where hearing loss is present as this can prevent the onset of dementia. The Lancet Commission also recommends taking measures such as safe listening and protecting the ears from excessive noise exposure as they prevent against hearing loss which is a leading cause of dementia.
