What was studied
A systematic review and meta-analysis of three prospective cohorts, with the pooled sample dominated by one large Japanese cohort.
What it contributes
The pooled estimate associates playing an instrument with lower observed dementia risk.
Where the evidence stops
Observational data remain vulnerable to confounding and selection. The estimate must not be translated into a promised percentage reduction from joining a band or starting an instrument.
