🧠 Episode Summary

Could a medication designed for weight loss change how we think about migraine prevention?
In this episode, host Diana Langworthy sits down with returning guest Dr. Natalie Heinrich, PharmD and student contributor Nena Abosi, PharmD Candidate 2026 to unpack a 2025 Headache pilot study evaluating liraglutide as an add-on therapy for adults with obesity and high-frequency or chronic migraine. The team breaks down study design, results, and limitations while questioning whether the observed benefit stems from weight loss, intracranial-pressure changes, or something else entirely.

💬 Key Takeaways

• Study Design: Prospective open-label pilot (n = 31) using liraglutide 1.2 mg daily × 12 weeks in adults with BMI > 30 kg/m² and ≥ 8 headache days/month unresponsive to ≥ preventives.
• Results: Headache days decreased by ~9 per month (≈ 50 % reduction); disability scores improved significantly, but BMI change was minimal.
• Mechanism: Benefit appeared independent of weight loss—raising curiosity about GLP-1 effects on intracranial pressure and CGRP release.
• Tolerability: Mild GI symptoms (~40 %), no discontinuations.
• Caveats: Small sample, no control group, single center — results are hypothesis-generating, not practice-changing.
• Clinical Pearl: Pilot studies like this spark conversation and awareness for emerging mechanisms while reminding clinicians to stay evidence-curious.
