ACHIEVE: hearing aids slow cognitive decline 48% in high-risk adults
Who, how long
977 older adults with hearing loss (70–84), 3 years
What they found
No difference overall, but in the higher-risk ARIC subgroup hearing aids slowed cognitive decline by 48%.
⚠ Caveat
The primary endpoint was negative; the subgroup result is hypothesis-generating, though pre-specified.
