The Claim
High coffee consumption (≥4 cups per day) is associated with a faster rate of decline in fluid intelligence and increased errors in pairs matching tasks over nearly a decade in adults aged 60–85, compared to moderate or no coffee consumption.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting 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.
Adults aged 60 to 85 who drink four or more cups of coffee per day show a faster decline in fluid intelligence and make more mistakes on memory matching tasks over a period of nearly ten years compared to those who drink less or no coffee.

Too much caffeine blocks signals that normally calm brain inflammation and clear harmful proteins, causing more inflammation and protein buildup that damages brain cells over time, leading to faster memory and thinking decline.
What the research says
1 studyStudy: Moderate coffee and tea consumption is associated with slower cognitive decline
Older adults who drank four or more cups of coffee a day lost their thinking skills faster and made more mistakes in memory games over time than those who drank less coffee.
