The CHOICE randomized clinical trial assessed the impact of hearing aid intervention on dementia progression in older adults with mild cognitive impairment (MCI) and moderate to severe hearing loss.
The primary outcome showed no statistically significant reduction in the conversion from MCI to dementia-level impairment over 24 months with hearing aid use.
Secondary outcomes revealed a notable increase in cognitive improvement rates in the hearing aid intervention group compared to education alone.
The intervention was safe and well-tolerated, with no reported study-related adverse events.
