Hearing Loss, Brain Health, and Dementia: What the Science Really Says

Hearing Loss, Brain Health, and Dementia: What the Science Really Says

Hearing loss is often dismissed as a minor inconvenience—but growing research suggests it may play a significant role in brain health and dementia risk. In this episode, Dr. Layne Garrett, founder of Timpanogos Hearing & Tinnitus, breaks down what the latest science actually shows about the connection between hearing loss, cognitive decline, and dementia.

Drawing on large-scale studies including the Lancet Commission, the ACHIEVE trial, and recent population research, Dr. Garrett explains how untreated hearing loss may increase cognitive load, contribute to social isolation, and change how the brain processes sound and memory. He also shares a real patient story that illustrates how proper hearing care can restore connection, reduce mental fatigue, and support overall cognitive health.

Importantly, this conversation avoids fear-based claims. While research is still evolving, hearing loss remains one of the largest modifiable risk factors for dementia—meaning it's something we can act on.

With over two decades of clinical experience using evidence-based tinnitus and hearing loss treatments, Dr. Garrett offers practical guidance on hearing evaluations, REM-verified hearing aid fittings, and why early intervention matters for protecting quality of life and brain health.
