"Long-term coffee drinking may be associated with a lower risk of developing dementia and more favorable cognitive health outcomes, according to a long-running analysis involving more than 130,000 people. The study, published online Feb. 9 in JAMA, found that among both men and women, people in the highest quartile of caffeinated coffee consumption (2-3 cups per day or more) had an 18% lower risk of dementia compared with those who reported little or no caffeinated coffee consumption."
"Caffeinated coffee drinkers in that highest quartile also had lower prevalence of "subjective cognitive decline" compared with people in the lowest quartile (7.8% versus 9.5%). In some measurements, people who drank caffeinated coffee also showed better performance on objective tests of overall cognitive function, according to the authors. Higher tea intake showed similar results, while decaffeinated coffee did not, suggesting that caffeine may be key to the neuro-protective effects."
Long-term caffeinated coffee intake of about 2–3 cups daily or more is linked with an approximately 18% lower risk of developing dementia compared with little or no caffeinated coffee. Among 131,821 participants in the Nurses' Health Study and the Health Professionals Follow-up Study tracked over decades, people in the highest caffeinated-coffee quartile showed lower dementia risk and lower prevalence of subjective cognitive decline (7.8% versus 9.5%) and in some measures better objective cognitive test performance. Higher tea intake showed similar associations, while decaffeinated coffee did not, suggesting caffeine may drive neuroprotective effects. Benefits were most pronounced at roughly 2–3 cups daily or 1–2 cups of tea; greater coffee intake produced similar results.
