Vertigo as a migraine phenomenon.

Migraine is a complex disorder with many different manifestations. There has been an increasing interest in the association of migraine and vertigo. Many different terms have been developed to describe this concept, the more popular being vestibular migraine, migrainous vertigo, and migraine-associated vertigo. The most commonly cited diagnostic criteria are that of Neuhauser though this has yet to be included in the International Classification of Headache Disorders (2nd edition). At this time, there is a lack of consensus regarding migraine-related vertigo and its pathomechanism. Regardless, a few randomized controlled prospective studies have been performed to evaluate the efficacy of various medications. Topiramate has been shown to be effective for migraine-related vertigo. At this time there is no specific treatment for migraine-related dizziness outside of conventional migraine management. The genetics have yet to be fully realized though an autosomal dominant familial migraine vertigo disorder has been identified.
