The Connection Between Hearing Loss and Dementia
It feels like a double whammy. As we age, we are likely to experience some degree of hearing loss — and now research is showing that hearing loss may be a factor in the risk of developing cognitive issues, even dementia.
In this article, originally published in Wellbeing Magazine, Dr. Grace Gore Sturdivant explores the growing body of evidence linking hearing health to cognitive decline, and why protecting your hearing now matters more than ever.
Research now consistently identifies untreated hearing loss as one of the most significant modifiable risk factors for dementia — a finding that has changed how clinicians, researchers, and patients think about what a routine hearing evaluation is actually for. The Lancet Commission on dementia prevention has included hearing loss in its list of the twelve most important lifestyle factors to address, placing it ahead of physical inactivity and smoking in terms of population-level impact. The relationship is not simply that hearing loss causes dementia, but that the two conditions are deeply intertwined through shared mechanisms involving cognitive load, social isolation, and neural atrophy. For most people, protecting their hearing has always felt like a quality-of-life issue — this research reframes it as something closer to a long-term investment in cognitive health.
