Introduction: Migraine is a disabling neurological disorder with a complex neurobiology. It appears as a cyclic disorder of sensory processing, affecting multiple systems beyond nociception. Overlapping mechanisms, including dysfunctional processing of sensory input from brain structures are involved in the generation of attacks.
Areas covered: This review provides a comprehensive synthesis on migraine neurobiology, which was additionally informed by search of research databases (PubMed, ClinicalTrials.gov). Findings from the most recent literature are integrated in a pathophysiological framework. By combining mechanistic insights and clinical trial data, this review highlights the trajectory of precision medicine in migraine treatment, offering a perspective on the near future of targeted and individualized therapeutic strategies.
Expert opinion: Recent advances in migraine neurobiology offer potential solutions to longstanding challenges. While targeted CGRP therapies have shown promise by addressing specific mechanisms, the pathophysiology of migraine suggests that combination therapies targeting multiple pathways could be beneficial in migraine prevention. The growing diversity of treatment options presents challenges in therapy selection, underscoring the need for predictive biomarkers. These innovations can optimize treatment strategies and improve patient outcomes. As the field progresses, personalized, multimodal approaches are poised to become the standard of care, significantly advancing precision medicine in this area.
