Numerous reports have shown that the prevalence of vertigo is higher in patients with migraine than in general po nllation and the prevalence of migraine is also higher in patients with recurrent vertigo of unknown origin than in cc, urols. Migraine-related vertigo is a vestibular disorder that manifests itself with spontaneous or positional rotational ve tigo or dizziness induced by head motion (head motion intolerance). Although recent studies have increased un ierstanding of the relationship between migraine and vestibular symptoms, the mechanism of migraine related vertigo is still obscure. A defective ion channel, primarily expressed in the brain and inner ear, may explain headache and ve ;tibular symptoms in patients with migraine related vertigo. Treatment is based on the repertoire of acute and prophylactic medications that are used for migrainous headaches. Controlled studies on the treatment of migraine-related vertigo are still lacking.
