The study evaluated the effects of coffee on the brain among 17,702 UK Biobank participants (aged 37 to 73), and found that those who drank more than six cups of coffee a day had a 53 percent increased risk of dementia.

“Drinking more than six cups of coffee a day can put you at risk for brain diseases like dementia and stroke,” said Kitty Pham, lead researcher on the study.
