Vestibular migraine: Diagnostic criteria. Consensus document of the Bárány Society and the International Headache Society

This work presents the diagnostic criteria for vestibular migraine, jointly formulated by the Committee for Classification of Vestibular Disorders of the Bárány Society and the Migraine Classification Subcommittee of the International Headache Society. The classification includes vestibular migraine and probable vestibular migraine. Vestibular migraine will feature in an appendix of the third edition of the International Classification of Headache Disorders as a first step for new entities, in accordance with the usual procedures of the International Headache Society. Probable vestibular migraine may be included in a later version of the International Classification of Headache Disorders, when further evidence has been gathered. The diagnosis of vestibular migraine is based on recurrent vestibular symptoms, a history of migraine, a temporal association between vestibular symptoms and migraine symptoms and on the exclusion of other causes of vestibular symptoms. The symptoms required for a diagnosis of vestibular migraine include various types of vertigo, as well as head motion-induced dizziness with nausea. Symptoms must be of moderate or severe intensity. The duration of acute episodes is limited to a window of between 5. min and 72. h. © 2013 Elsevier España, S.L.
