Hearing Aids and Brain Health: Slowing Cognitive Decline

Dear Atlas,

Is it true that wearing OTC Hearing Aids can help slow the decline of brain function?

When hearing declines, the brain works overtime to decode fuzzy sounds. That extra load can strain memory, thinking, and decision-making skills—also known as ‘cognitive’ functions. Over time, this can contribute to changes in brain structure and function associated with ‘cognitive decline’, also referred to as dementia. We now know hearing aids and brain health are related. Imaging studies support this link, and hearing loss shares risk factors with dementia, including age and vascular disease.

The good news: treating hearing loss helps. In the ACHIEVE trial (Lin et al., Lancet, 2023), adults at risk for cognitive decline who used hearing aids demonstrated a 48% slower decline in thinking and memory over a three-year period. Aim for 6–7 hours of daily OTC hearing aid wear.

Protect your cognitive functions with this ‘Brain Health Recipe’ 

Move: 30–35 minutes of moderate–intense aerobic activity 4×/week, plus strength and flexibility 2×/week.

Train your brain: 30 minutes of computer-based brain training exercises 3×/week and regular social, mentally challenging activities.

Eat smart: Follow the MIND diet—leafy greens, berries, nuts, whole grains, olive oil, fish; limit sugar and unhealthy fats.

Monitor health: Keep tabs on blood pressure, weight, and labs; manage risks like hypertension, obesity, diabetes, depression, smoking, alcohol misuse, inactivity, air pollution, and traumatic brain injury.

The US POINTER study (Baker et al., Journal of American Medical Association, 2025) found this combined lifestyle approach improves cognition. Watch for early warning signs (e.g., memory lapses affecting daily life, planning problems, word-finding issues, confusion about time/place, or personality changes). If you are concerned, discuss this with a family member or caregiver.

Warmly,
