Hearing Aids, Could Help Prevent Dementia, Study Suggests.br Scientists have warned that hearing loss may increase a person's risk of developing dementia.br 'Newsweek' reports that new research suggests that br hearing aids may be able to prevent or delay br the onset and progression of cognitive decline. .br According to data from the Centers for Disease br Control and Prevention in 2014, over 5 million people br in the U.S. over the age of 65 live with dementia.br After numerous studies found a link between hearing loss br and cognitive decline, many began to speculate that br hearing impairment could be a risk factor for dementia.br The authors found that people br with hearing loss who did not br use hearing aids had a 20 percent br higher risk of dementia than br those with normal hearing, Tom Dening, professor of dementia research br at the University of Nottingham, via 'Newsweek'.br People who used hearing aids br for their hearing loss did not br have such a high risk (6, which br was only just significantly above br the risk for normal hearing), Tom Dening, professor of dementia research br at the University of Nottingham, via 'Newsweek'.br People who used hearing aids br for their hearing loss did not br have such a high risk (6, which br was only just significantly above br the risk for normal hearing), Tom Dening, professor of dementia research br at the University of Nottingham, via 'Newsweek'.br This suggests that br hearing aid use may help br to protect against dementia, Tom Dening, professor of dementia research br at the University of Nottingham, via 'Newsweek'.br The team from the University of br Southern Denmark published their findings br in the journal 'JAMA Otolaryngology.'.br 'Newsweek' reports that other experts have warned br that the findings, while promising, do not confirm that br hearing aids are a definite way of preventing dementia. .br Studies of this kind should br be interpreted with care, Jason Warren, professor of neurology at br University College London, via 'Newsweek'.
