A new study has concluded that people who wear a hearing aid for age-related hearing problems maintain better brain function over time than those who do not.
It builds on research in recent years pulled together by the Lancet Commission on Dementia Prevention, Intervention and Care, through which hearing loss emerged as an important risk factor for dementia. This research suggests that wearing a hearing aid may mitigate that risk.
The research was conducted by the University of Exeter and King’s College London and is presented at the Alzheimer’s Association International Conference in LA. In the PROTECT online study of 25,000 people aged 50 or over. The findings provide early evidence that encouraging people to wear an effective hearing aid may help to protect their brains and reduce their risk of dementia.
PROTECT lead Dr Anne Corbett, from the University of Exeter, said: “Previous research has shown that hearing loss is linked to a loss of brain function, memory and an increased risk of dementia. Our work is one of the largest studies to look at the impact of wearing a hearing aid, and suggests that wearing a hearing aid could actually protect the brain. We now need more research and a clinical trial to test this and perhaps feed into policy to help keep people healthy in later life.”
