Migraine-related vertigo: towards a distinctive entity.

Both migraine and vertigo are common complaints. Although they may coincide by chance, there is growing evidence for a clinical entity of recurrent vestibular symptoms related to migraine. This syndrome implies a possible causal relationship although the pathophysiology of migraine-related vertigo has not been fully elucidated. A migrainous aseptic inflammation is thought to create a central sensitivity that spreads from the trigeminal to the vestibular system. Diagnostic criteria for migraine-related vertigo are proposed. Treatment is based on anti-vertiginous drugs for acute interventions and prophylactic measures as are taken for migraine headaches. Multicenter, prospective controlled studies are highly warranted.
