Clinical features of vestibular migraine in a neurological clinic

Abstract:

Objective：To explore the clinical characteristics of vestibular migraine（VM） in a neurological clinic and to test the criteria of the International Classification of Headache Disorders 3rd edition beta version（ICHD-Ⅲ beta） in practice. Methods：Retrospective analysis was made on 39 patients with VM referred to the neurological clinic in the First Affiliated Hospital of Chongqing Medical U－niversity from June 2013 to June 2014. The demographic and clinical characteristics of these patients were analyzed. Results：The mean onset age of migraine was （32.7±10.5） years old and vertigo was （36.6±10.3） years old. The most common migraine subtype was migraine without aura（82%），followed by migraine with aura（10%） and chronic migraine（8%）. Spontaneous vertigo was reported in 90% patients and the duration of vestibular symptoms was varied from seconds to days. Photophobia and phonophobia（74%） were the most frequently reported associated symptoms. However，33% patients could not fulfill with criterion C and 8% patients could not fulfill with criterion B. Conclusion：The clinical features of VM in neurological clinic are similar with those in Western studies except the low proportion of migraine with aura among patients with VM. VM diagnostic criteria in ICHD-Ⅲ beta might be further modified，including the definition of vertigo episodes and the new-adding migraine subtypes.
