While no direct connection has been found, it is generally accepted that people with hearing loss are definitely at a greater risk of dementia. For instance, when an individual has hearing loss, the brain has to work harder than it should have to in order to decipher sound. As hearing loss increases, demands on the brain increase. Overtaxing the brain over a long period of time may open the door to dementia. The difficulty of living with hearing loss may also cause someone to withdraw from people out of embarrassment or frustration, which can lead to social isolation—a recognized risk factor for dementia.
