Migraine Associated Vertigo (MAV). What causes the vertigo in MAV ? There are several theories -- Vascular -- patients with migraine sometimes experience spasm of blood vessels, including occasional strokes. Blood vessel spasm in the ear or brainstem may cause vertigo. Neurotransmitter changes -- patients with migraine have irregularities in neurotransmitters, especially serotonin. Cerebellar disturbance -- migraine alters metabolism in the cerebellum. Sensory exaggerations -- in migraine, all senses can be more acute. This may make patients with migraine more likely to experience motion sickness and amplify the effects of small amounts of vestibular disturbance that other people might not notice. There has also long been noted a close association between Menieres disease and Migraine. dizziness-and-balance/disorders/central/migraine/mav.html
