Hearing aid intervention in older adults with mild cognitive impairment and moderate-to-severe hearing loss did not significantly reduce conversion to dementia-level impairment at 24 months.
- Why it matters: Hearing loss is a modifiable risk factor for cognitive decline, but whether hearing intervention can stabilize or improve cognition in people with MCI remains uncertain.
- What they did: In a multicenter open-label randomized clinical trial in Shanghai, 703 participants with CDR global 0.5 were assigned to hearing aid intervention (n = 353) or hearing care education (n = 350) and followed for 24 months.
- The result: Dementia-level conversion was 3.09% vs 4.74% (risk difference -2.07%; P = .23), while cognitive improvement (CDR = 0) was higher with intervention (15.34% vs 2.36%), with no study-related adverse events reported.
