The data on hearing loss and cognitive decline, dementia, and Alzheimer’s disease is as compelling as it is incomplete. But with every new study, the case continues to mount for hearing healthcare as being one of the most impactful things a person can do to reduce their risk for cognitive decline and dementia. In fact, The Lancet Commission in 2017 and 2020 showed that hearing loss is the number-one “modifiable risk factor” in middle life, and is linked to around 8% of worldwide dementia cases. And, two weeks ago, the landmark ACHIEVE study was published, suggesting that hearing aids combined with hearing care may reduce the risk for dementia in some patient populations (see below).
