The Study
Statin use and dementia risk: A systematic review and updated meta‐analysis
This study looked at 55 other studies that watched people over time to see if those who took statins were less likely to get dementia. It found a link, but it can't prove that statins caused the lower risk because people who take statins might also do other healthy things.
Analysis score
Maximum 100 for a systematic review with meta-analysis.
Where the score came from

Key takeaways
Summary
Based on the study abstract and findings.

- 3If they take them for over 3 years, the chance drops by 63%.
