Why it matters

The 2024 Lancet Commission puts untreated hearing loss at about 7% of dementia cases, the largest single modifiable factor, and untreated vision loss at about 2% [1]. Treatment helps: in the ACHIEVE trial, hearing aids cut three-year cognitive decline by about half in at-risk older adults [2], and regular hearing-aid users had 24% lower mortality than non-users with hearing loss [3].
