A prospective cohort study involving 131,821 participants from the Nurses' Health Study and Health Professionals Follow-up Study found that drinking 2 to 3 cups of caffeinated coffee or 1 to 2 cups of tea daily is linked to a lower risk of developing dementia and enhanced cognitive function. Over 43 years, 11,033 dementia cases were recorded. The highest quartile of coffee drinkers showed an 18% reduced likelihood of dementia compared to the lowest quartile. These associations persisted across various demographics, although the effects were less pronounced in older individuals.
