The Claim
Higher caffeinated coffee intake is associated with a 0.11-point higher TICS score and a nonsignificant 0.02-point higher global cognition z-score in a subset of 86,606 women from the Nurses’ Health Study followed for decades.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In a large group of women followed for many years, those who drank more caffeinated coffee had slightly higher scores on cognitive tests measuring memory and thinking skills, though overall cognitive performance showed no significant change.
See the scientific wording
Higher caffeinated coffee intake is associated with modestly better objective cognitive performance, as measured by a 0.11-point higher TICS score and a nonsignificant 0.02-point higher global cognition z-score, in a subset of 86,606 women from the Nurses’ Health Study followed for decades.
Caffeine enters the brain and stops a chemical called adenosine from slowing down nerve cells. This lets nerve cells fire more often and release more signaling chemicals, which improves how well brain circuits process information and remember things.

1 studyStudy: Coffee and Tea Intake, Dementia Risk, and Cognitive Function.
Women who drank more caffeinated coffee over many years scored slightly better on memory and thinking tests, though the overall improvement was very small and not always clear-cut.
