The Claim
Habitual coffee consumption is not statistically significantly associated with white matter hyperintensity volume in the brain, indicating no evidence that coffee influences this marker of small vessel disease.
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.
Regular coffee drinking shows no measurable link to white matter hyperintensity volume, a brain imaging marker of small blood vessel damage.
See the scientific wording
There is no statistically significant association between habitual coffee consumption and white matter hyperintensity volume, a marker of small vessel disease in the brain, suggesting that coffee’s link to dementia may not be mediated through cerebrovascular damage.
Coffee consumption does not trigger any measurable change in the small blood vessels of the brain that would lead to increased white matter damage.
What the research says
1 studyStudy: High coffee consumption, brain volume and risk of dementia and stroke
This big study found that drinking coffee regularly doesn’t seem to increase or decrease the tiny brain damages called white matter hyperintensities, which are often linked to aging and blood vessel problems. So, if coffee affects dementia, it’s probably not because it harms brain blood vessels.
