Rethinking CGRP: New Insights on Migraine Biomarkers

Research Summary

A recent study published in Neurology examined whether plasma CGRP levels differ between migraine sufferers and healthy individuals. Researchers found that individuals with migraines had slightly lower plasma CGRP concentrations (125 pmol/L) compared to healthy controls (151 pmol/L), challenging the belief that elevated CGRP is indicative of migraines. The study included 588 migraine patients and 147 matched controls, focusing on various migraine subtypes and treatment statuses. No significant differences were observed across migraine subtypes, clinical status, or preventive medication use. These findings suggest that plasma CGRP may not be a reliable biomarker for diagnosing or monitoring migraine.
