Abstract

This review aimed to summarize current evidence on the diagnostic criteria, pathophysiological mechanisms, differential diagnosis, and treatment approaches of vestibular migraine. A systematic literature search was conducted in PubMed/MEDLINE, Web of Science, and the Cochrane Library for studies published between May 2021 and May 2026. The search focused on vestibular migraine, migrainous vertigo, migraine-associated vertigo, diagnostic criteria, pathophysiology, treatment, prophylaxis, rehabilitation, and calcitonin gene-related peptide (CGRP)-related therapies. Study selection followed a PRISMA-informed process, and findings were synthesized narratively because of heterogeneity in study design, populations, interventions, and outcome measures. A total of 663 records were identified, and 72 studies were included in the final synthesis. Current evidence supports vestibular migraine as a complex disorder involving trigeminovascular activation, CGRP signaling, central sensitization, vestibulo-thalamo-cortical networks, and cerebellar compensation. Diagnosis remains primarily clinical and requires careful assessment of attack duration, vestibular symptom type, migraine-associated features, and exclusion of alternative vestibular or vascular disorders. Treatment evidence remains limited and heterogeneous. Lifestyle modification, conventional migraine prophylaxis, vestibular rehabilitation, and CGRP-targeted therapies may be useful in selected patients, but robust vestibular…
