A 43-year study of over 131,000 participants found that moderate consumption of caffeinated coffee (2-3 cups daily) or tea (1-2 cups daily) was associated with an 18% lower dementia risk and better cognitive performance, with benefits appearing strongest for caffeine rather than decaffeinated coffee. Researchers from Mass General Brigham and Harvard institutions published their findings in JAMA, noting that caffeine's brain-protective effects appeared consistent regardless of genetic predisposition to dementia.
