The Claim
Moderate caffeine consumption is associated with an 18% reduced risk of developing dementia.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who drink a moderate amount of coffee or tea may be less likely to develop dementia later in life — about 18% less likely, according to this claim.

Moderate caffeine consumption is associated with an 18% reduced risk of developing dementia.
What the research says
2 studiesThis study found that people who drank coffee or consumed caffeine regularly, especially in moderate amounts, had slower memory loss and less severe dementia symptoms over time — which supports the idea that moderate caffeine can help lower dementia risk.
The study found that drinking tea may help lower dementia risk, but caffeine alone—whether from coffee or other sources—didn’t show a clear benefit. So, the claim that caffeine cuts dementia risk by 18% isn’t backed by this research.
