A study published in The Lancet Public Health last spring suggesting that hearing aids may reduce dementia risk has been retracted due to a coding error identified by the authors. The error led to the data for people with and without hearing aids being switched, rendering their findings false. The journal takes research integrity seriously and follows best-practice guidance, retracted the study, and thanked the scientists who prompted the re-examination of the data. However, other studies have suggested a link between hearing and dementia, with one study showing a 61% higher dementia prevalence in those with moderate to severe hearing loss and another showing that hearing aids significantly reduce the risk for cognitive decline and dementia.
