Summary

This study aims to understand how the information given to patients about their treatment affects their response to migraine medication. Researchers will give 60 adults with chronic migraine four different treatment conditions in a random order and measure changes in headache intensity, number of headache days, and side effects. The goal is to improve how we evaluate preventive migraine treatments by separating the drug's effect from the placebo effect.
