The Claim
Higher caffeinated coffee intake is associated with modestly better objective cognitive performance as measured by the TICS score in older adults, but not with global cognition.
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.
Older adults who drink more caffeinated coffee show slightly better scores on cognitive tests measuring memory and thinking skills, but there is no clear link to overall cognitive function.
See the scientific wording
Higher caffeinated coffee intake is associated with modestly better objective cognitive performance, as measured by the TICS score, in older adults, though the association with global cognition was not statistically significant.
Caffeine blocks brain chemicals that slow down nerve cell activity, making nerve cells more active and improving focus. This helps the brain process information faster in tasks that need attention and memory, like those measured by the TICS score.
What the research says
1 studyStudy: Coffee and Tea Intake, Dementia Risk, and Cognitive Function.
People who drink more caffeinated coffee tend to do slightly better on memory and thinking tests, and this study found that exact pattern — especially with about 2-3 cups a day. But the improvement is small and not always clear-cut.
