Abstract
Question: Is long-term intake of caffeinated and decaffeinated coffee associated with risk of dementia and cognitive outcomes?
Findings: In this prospective cohort study of 131,821 individuals from 2 cohorts with up to 43 years of follow-up, 11,033 dementia cases were documented. Higher caffeinated coffee intake was significantly associated with lower risk of dementia. Decaffeinated coffee intake was not significantly associated with dementia risk.
