So, can treating hearing loss help keep us mentally sharp?
There is no current proof that hearing loss treatment can prevent cognitive decline, but two studies strongly suggest it may help.
One studied people over a 25-year period and found that those with self-reported hearing loss who did not wear hearing aids showed evidence of accelerated cognitive decline, while those with hearing loss who did wear hearing aids had no more cognitive decline than their normal-hearing peers4.
A recent study was even more interesting5. The study concluded that managing or treating hearing loss in mid-life is one of 12 things you can do to help prevent dementia. And — more importantly — hearing loss was the number one risk factor they recommended you could modify to “reduce the incidence of dementia or substantially delay its onset.”
In fact, researchers suggest that hearing loss treatment could prevent up to 9 percent of the 47 million dementia cases in the world6.
