People who drink a few cups of tea or coffee daily show a lower risk of dementia, researchers say.
A US study followed more than 130,000 adults for up to 43 years.
Those drinking two to three coffees or one to two teas daily had a 15–20% lower dementia risk.
Caffeinated coffee drinkers also showed slightly less cognitive decline than non-drinkers.
The findings were published in the Journal of the American Medical Association.
Researchers caution the study cannot prove caffeine protects the brain.
Other lifestyle factors may explain the reduced risk.
Lead author Yu Zhang said the results align with plausible biology.
Coffee and tea contain caffeine and antioxidants that may reduce inflammation and improve vascular health.
Experts stress healthy lifestyles remain key to protecting brain function.
