Hearing aids may be key to slowing dementia – new study tests easy access
NCT ID NCT07288463
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This pilot study will test whether over-the-counter (OTC) hearing aids are practical and acceptable for older adults with mild-to-moderate hearing loss who are at risk for dementia. Forty participants aged 50 and older will either use the hearing aids right away or wait three months. The study measures how many people sign up, stick with the devices, and find them helpful, with the goal of designing larger trials to improve hearing care and cognitive health.

- What this could lead to
- If successful, this study could show that OTC hearing aids are a practical way to improve hearing care access, potentially helping to reduce dementia risk in older adults.
- What could go wrong
- This is a small pilot study with only 40 participants, so results may not apply to everyone. It focuses on feasibility, not on proving that hearing aids prevent dementia.
