The Study
The Role of Magnesium in Neurological Disorders
This study is like a summary of many different smaller studies that looked at whether magnesium might help with brain problems. It says 'maybe' and 'could be linked to' but doesn't prove that taking magnesium actually fixes anything. It's like saying 'people who eat more apples seem to get fewer colds' — but we don't know if the apples are the reason.

Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.
Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — for migraines and depression, magnesium’s effect is meaningful and comparable to some medications.
- 2For stroke, it’s a modest but important dietary benefit.
- 3For other conditions, it’s too early to tell.
- 4For migraines: magnesium reduced attacks by 20–30%.
- 5For depression: people who ate more magnesium had 19% lower risk.
- 6For stroke: every 100 mg/day of magnesium lowered risk by 2–13%.
- 7For Alzheimer’s and Parkinson’s: no clear benefit found yet.
