The Claim
Coffee consumption is not associated with changes in reaction time or numeric memory over a period of nearly a decade in adults aged 60–85, despite being associated with fluid intelligence and pairs matching errors.
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.
Over nearly ten years, drinking coffee does not change how quickly older adults react or how well they remember numbers, but it is linked to differences in fluid intelligence and performance on pair-matching tasks.
See the scientific wording
Coffee consumption is not associated with changes in reaction time or numeric memory over nearly a decade in adults aged 60–85, despite its association with fluid intelligence and pairs matching errors.
Coffee's caffeine blocks a brain chemical that normally slows down nerve cell activity, which reduces inflammation and prevents harmful protein buildup in the brain. This keeps certain thinking skills stable over time, but it does not change how fast a person reacts or how well they remember numbers.
What the research says
1 studyStudy: Moderate coffee and tea consumption is associated with slower cognitive decline
This study found that older adults who drank coffee didn’t get worse at thinking or remembering over nearly 10 years, even though coffee didn’t help them either. So, it supports the idea that coffee doesn’t hurt how fast they react or remember numbers.
