I know plenty of people who drink coffee and, honestly, I don't see much brain improvement! ahahah

Who doesn't drink coffee? I'd be concerned that coffee is a proxy for something else.

I want to believe. I love coffee. But who funded these "researchers"? How thorough were they in trying to falsify this conclusion? Causation is very difficult to prove, of course. But all this research seems to be based on is correlation. So, people who drink a moderate amount of coffee do better on cognitive tests? Did they control for education background? Profession? Physical fitness? I haven't "trusted the science" for a while now. I want to believe coffee and red wine and other things I like are good for me, but forgive me if I take this "science" with a pinch of salt.

Decades of data suggest people who stick to a couple of brews fare better in terms of gray matter

A decades-long study suggests that your daily caffeine fix might be doing more than jolting you through morning meetings – it could also be quietly helping your brain hold it together.

 more than 130,000 people for over four decades and found that those who regularly consumed moderate amounts of caffeinated coffee or tea had an 18 percent lower risk of developing dementia compared to those who rarely touched the stuff.

Caffeine swiggers also scored better on some cognitive tests and were less likely to complain about memory slips, according to the study.

Before anyone starts mainlining espresso shots in the name of science, the apparent benefits weren't tied to heroic levels of caffeine intake, just to steady, mid-range consumption – roughly two to three cups a day – suggesting that consistency matters more than turning yourself into a walking coffee bean.
