Summary
This study looked at how galcanezumab, a newer migraine prevention drug, affects the brain. Researchers used MRI scans to see if the drug changes brain structure in people with chronic migraine. The goal was to learn more about where the drug works, not to test if it helps symptoms. 64 adults with frequent migraines took part.
