The idea
Hearing loss is the largest single modifiable dementia risk factor in Livingston's estimates, entry 2154, but a hearing-aid trial found no overall cognitive benefit, entry 2155.
In practice
Only about sixteen percent of adults twenty to sixty-nine who could benefit from hearing aids having ever used them, entry 1807.
Where people slip
Whether hearing loss causes dementia or signals it remains unresolved, entry 2154 notes.
