Chronic Pain and Substance Use Disorders Have Shared Genetics

A new study includes data from more than 800,000 people with chronic pain, with lessons for the migraine field, too.

Looking Migraine in the Eye

A non-invasive imaging tool reveals changes in the retinal microvasculature during migraine. The approach could help researchers better understand the pathophysiology of the condition and perhaps be of clinical use, too.

Environmental Chemicals Can Trigger Migraine Signaling

A proof-of-concept study in mice shows that pesticides and pollutants activate migraine signaling pathways via the ion channel TRPA1. It’s unclear if the findings relate to migraine in people.

Meeting the Challenge of Cluster Headache: A Conversation with Andrea Carmine Belin

In this Migraine Science Collaborative interview, Andrea Carmine Belin chats about her career, the clinical problem of cluster headache, and recent research that is driving the understanding of cluster headache forward.

A Novel Prolactin Antibody Prevents Pain Behaviors in Female Mice

The new approach paves the way for a better understanding of prolactin in female-predominant conditions, including migraine and pain disorders. But targeting prolactin as a potential treatment approach in people faces significant challenges.

Does Aura Really Initiate Migraine Attacks? Challenging the Conventional Wisdom

Neuroimaging findings from a single patient suggest that aura may be an epiphenomenon, with no causal role in the onset of an attack.

P2X7 Signaling Contributes to Meningeal Sensitization

Researchers provide a new explanation for how cortical spreading depression affects afferent nociceptive neurons in the meninges.

A Neuroimmune Signaling Pathway Drives Chronic Headache

A new study in mice finds that CCL2-CCR2 signaling in macrophages and T cells sensitizes trigeminal ganglion neurons, driving chronic headache in migraine models. With synergistic effects on CGRP, the pathway could be a new therapeutic target for migraine.

Does CGRP Inhibition Quiet the “Migraine Brain”?

Three months of galcanezumab treatment reduced the incidence of premonitory symptoms and number of triggers followed by headache, even in patients classified as “non-responders” to the drug.
