Description
Hearing loss in midlife is one of the largest changeable risk factors for dementia, and Goncalves and co-authors tested its link with thinking skills in a Brazilian cohort. They followed 805 adults in the São Paulo arm of a national health study across three waves spanning about a decade. Hearing was measured with standard tone tests, and cognition with six tests covering memory, word fluency, and executive function.
Sixty-two participants had hearing loss at the start. Over the follow-up, that group lost ground on the combined cognitive score faster than the rest, even after accounting for social, lifestyle, and health differences. The effect was small per year but steady. The authors estimate that hearing loss accounts for about seven percent of dementia cases in Brazil. They conclude that preventing or treating midlife hearing loss could help slow cognitive decline.
