Calcitonin gene-related peptide (CGRP) is a key neuropeptide in migraine pathophysiology and treatment. This study investigates whether CGRP administration can trigger aura in individuals with a diagnosis of migraine with aura.
Recent open-label findings show that calcitonin gene-related peptide (CGRP), a key player in migraine, can trigger aura attacks-despite its limited ability to cross the blood-brain barrier. This suggests CGRP might induce migraine aura via trigeminovascular activation, the same pathway involved in migraine headache. If confirmed, this could reshape treatment strategies for patients diagnosed with migraine with aura. To validate this effect and rule out nocebo influence, a randomized, double-blind, placebo-controlled trial is essential. Its outcomes could inform future therapies targeting the migraine-aura connection.
