Hearing loss has long been linked to an increased risk of cognitive decline and dementia. Researchers from Carleton University in Ontario are providing fresh insights into how hearing loss impacts brain structure and function by draining away cognitive reserve over time.
Brain drain matters
Using MRI and fMRI imaging techniques, clinical audiologist and PhD student Imola MacPhee can visualize the effects of hearing loss on the aging brain.
Her research demonstrates that hearing loss contributes to
- Cortical thinning, a key biomarker of dementia risk.
- Disrupted activity patterns in auditory processing.
These results show how hearing loss triggers a cascade of brain changes that reroute and deplete precious neurological resources.

Prioritize hearing health
The takeaway is clear: Left untreated, hearing loss accelerates cognitive aging and dementia risk by taxing scarce neural resources.
The good news is that early intervention can help shore up shrinking brain reserves.
By prioritizing hearing health through regular screenings and hearing aids, you can quell the "brain drain" effect and keep your mind sharp longer.
