The Claim
Consuming more than 6 cups of coffee per day is associated with a 53% higher odds of developing dementia in adults aged 37–73 compared to consuming 1–2 cups per day, after adjustment for age, sex, socioeconomic status, and other lifestyle factors.
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.
Adults who drink more than six cups of coffee daily have a 53% higher odds of developing dementia than those who drink one to two cups daily, after accounting for age, sex, socioeconomic status, and other lifestyle factors.
See the scientific wording
Consuming more than 6 cups of coffee per day is associated with a 53% higher odds of developing dementia in adults aged 37–73, compared to consuming 1–2 cups per day, after adjusting for age, sex, socioeconomic status, and other lifestyle factors, suggesting that very high coffee intake may be linked to increased neurodegenerative risk.
Drinking too much coffee over time causes the brain's blood vessels to narrow, which lowers the flow of blood and nutrients. This slows down the removal of harmful waste proteins that build up in the brain, leading to damage in brain cells and increased risk of dementia.
What the research says
1 studyStudy: High coffee consumption, brain volume and risk of dementia and stroke
This big study found that people who drink more than six cups of coffee a day are about 53% more likely to get dementia over time than those who drink one or two cups, even after accounting for other health habits.
