Though evidence indicates that treating hearing loss with hearing aids (HAs) could reduce dementia risk, the effects on biomarkers of Alzheimer's disease and related dementias (ADRD) remain unknown.

Signed responses from readers of the wire.
If the study shows hearing-aid use reduces Alzheimer's-related plasma biomarkers, it would strengthen the case for early hearing rehabilitation as a potential dementia-prevention strategy, though findings should be weighed by sample size and study design before changing practice.
Establishing whether hearing-aid use influences objective Alzheimer's disease biomarkers — rather than just cognitive test scores — would substantially strengthen the biological rationale for hearing rehabilitation as a dementia-prevention intervention.
