Plasma CGRP Levels in Migraine: A Registry for Migraine Study

What Was Tested

Researchers studied CGRP (Calcitonin Gene-Related Peptide) in the context of migraine in this observational study publication.

Calcitonin gene-related peptide (CGRP) plays a central mechanistic role in migraine and is an established drug target.

However, it remains unclear whether peripheral plasma CGRP levels meaningfully reflect disease activity.

Regression models were performed to assess associations with clinical variables.

Who Took Part

The abstract describes 4 participants taking part.

The age groups tagged for this paper are adults and middle-aged adults, both men and women.

This cross-sectional observational study enrolled adults (≥18 years) with migraine with aura, migraine without aura, or chronic migraine primarily from specialized care.

Healthy controls without personal or first-degree family history of primary headache disorders were mainly recruited through web-based advertisement.

How the Study Was Run

Venous blood was obtained by antecubital phlebotomy, and plasma CGRP was quantified in duplicate using a validated high-affinity radioimmunoassay.

Controls were matched 1:4 to participants with migraine on age, sex, body mass index, and storage duration.

The primary outcome was between-group difference in plasma CGRP concentrations.

Group comparisons were performed using Mann-Whitney U tests.

What Was Measured

The subject headings attached to it are Calcitonin Gene-Related Peptide, Cross-Sectional Studies, Migraine Disorders, Registries and Biomarkers.

What This Means in Plain Language

This is an observational study of CGRP (Calcitonin Gene-Related Peptide) in 4 participants in people with migraine.

With fewer than 40 people, it is a small study, so it is better read as an early signal for further research than as a settled answer.

Its findings take up roughly 8 sentences of the abstract and are left out here on purpose; the source paper is the place to read them.

The publication is from 2026 (Neurology), a journal based in United States.
