Hearing Loss and Dementia

January 19, 2018

 It is no secret that as we get older many of us have impaired hearing. In fact it is estimated that about 48 million Americans have some degree of hearing loss. Most of these people never seek treatment, partly because of the cost of hearing aids and partly because many believe that some hearing loss is normal and harmless.

Unfortunately there is growing evidence that hearing loss may increase the risk of cognitive problems. In a recent study published in a well regarded medical journal the authors evaluated the cognitive and hearing levels of 1,984 older adults. They compared those with normal hearing to those with hearing loss. Those with hearing loss had lower scores on baseline cognitive testing and were more likely to have significant impairment after six years, The authors also found that the worse the hearing, the worse the mental decline.

The take away message is that there is good reason to treat hearing loss. If doing so even slightly heads off dementia it would be a big plus.
