Neurodegenerative conditions are becoming increasingly common, affecting memory, thinking, and the ability to manage everyday tasks. Scientists have long searched for lifestyle habits that could help protect the brain, and caffeinated coffee appears to be one promising factor.

On February 7, physician and scientist Eric Topol drew attention to the study in a post on X, highlighting how consistent caffeine intake may support long-term cognitive health. The research has sparked global interest, especially among those who already enjoy coffee as part of their routine.



What Did The Study Find?

Eric shared the findings with graphs and wrote, " Coffee and improved cognition, reduced dementia >130,000 people followed 37 years. Benefit seen only with caffeinated coffee or tea and most pronounced ~2 cups/day."

The study followed nearly 130,000 participants over 37 years, making it one of the most extensive investigations into caffeine and brain health. Researchers observed that people who regularly consumed caffeinated coffee or tea showed a lower incidence of dementia compared with those who drank little or none.
