Why Treating Hearing Loss May Protect Your Brain

Hearing loss is often dismissed as an inconvenience—but growing research shows it may be far more important to brain health than most people realize. In this episode, Dr. Layne Garrett breaks down findings from a major Framingham Heart Study analysis that followed more than 2,100 adults for 15 years and revealed a striking connection between even mild hearing loss and increased dementia risk.

You'll learn how untreated hearing loss increases cognitive load, worsens speech clarity, and contributes to social isolation—each of which places additional strain on the brain. Dr. Garrett also explains how brain imaging shows changes in brain volume and white matter integrity in people with hearing loss, and why those changes matter long before memory problems appear.

The episode explores the role of genetics, including the APOE ε4 risk factor, while emphasizing that hearing loss remains one of the most controllable contributors to long-term cognitive health. You'll also hear why properly fitted hearing aids—verified with Real Ear Measurement—may help reduce auditory load and keep the brain more engaged over time.

Drawing on more than two decades of clinical experience in tinnitus and complex hearing loss, Dr. Garrett offers practical, evidence-based guidance for anyone over 45 who wants to protect their hearing, their brain, and their quality of life.
