Glymphatic System and PACAP: New Insights into Migraines

Research Summary

A recent review in the journal Life (Basel) delves into the evolving understanding of migraine pathophysiology, specifically focusing on the glymphatic system and the peptide PACAP. While CGRP has been a major topic of debate, this article highlights how the failure of glymphatic clearance can lead to the buildup of inflammatory mediators and neuropeptides, triggering migraine attacks via trigeminovascular pathways. The review connects neuroinflammation, CGRP, cortical spreading depression (CSD), and sleep disturbances with the glymphatic system's role in migraines. Additionally, it discusses how glymphatic dysfunction might amplify PACAP-mediated signaling, offering new insights into migraine's underlying mechanisms.
