CBS News medical contributor Dr. Celine Gounder breaks down a new study that shows daily coffee or tea might help reduce the risk of dementia.

A recent study followed more than 130,000 adults over 40 years and found that those who drank two to three cups of coffee or one to two cups of tea daily had a slightly lower risk of dementia compared to those who consumed no caffeinated drinks or only decaf. However, the reduction in risk was minor, amounting to about half a year of cognitive aging, and researchers caution that the findings show only an association, not a direct cause-and-effect relationship.

Medical experts, including Dr. Celine Gounder, advise interpreting these results with caution, noting that such studies may reflect other health behaviors rather than a protective effect of caffeine. Dr. Gounder emphasized that proven methods to reduce dementia risk include exercise, a healthy diet, weight management, and treating hearing loss.
