Abstract

Migraine is among the most prevalent neurological disorders in children and adolescents and is a leading cause of functional disability, school absenteeism, and impaired quality of life. Pediatric migraine is not merely a younger manifestation of the adult disease; rather, it exhibits distinct clinical phenotypes, developmental neurobiology, triggers, and treatment responses. The growing recognition of its long-term burden underscores the need for updated, pediatric-focused, evidence-based guidance. This narrative review synthesizes contemporary evidence on pediatric migraine across the lifespan, integrating epidemiology, genetic susceptibility, and age-dependent neurobiological mechanisms. Key clinical features, including migraine equivalents and episodic syndromes associated with migraine, are discussed alongside diagnostic considerations using the International Classification of Headache Disorders, third edition, and validated pediatric disability assessment tools. Acute and preventive management strategies are reviewed in detail, encompassing optimized use of non-steroidal anti-inflammatory drugs and triptans, antiemetics, nerve blocks, neuromodulation devices, and emerging targeted therapies such as calcitonin gene-related peptide monoclonal antibodies and gepants. Evidence-based non-pharmacological interventions, including lifestyle optimization, sleep hygiene, cognitive-behavioral therapy, and comorbidity management, are also integral components of care.
