[Research status of vestibular migraine]

Pathogenesis, clinical characteristics and treatments of vestibular migraine(VM) in recent years were retrospectively analyzed. The results showed that VM had diversified vestibular symptoms. VM may show a mild central and peripheral vestibular dysfunction during ictal and interictal period. Although no specificity, it could provide important references to identify VM. The pathogenesis of VM, which depended upon the clues of migraine, had been supposed to be probably related to genetic susceptibility, neurotransmitter changes induced by trigeminal nerve, and abnormal integration of central signal, and further exploration of functional abnormalities in brain-related areas showed by functional imaging technology may shed light on the pathogenesis of VM. Until now, the pharmacotherapies of VM have been still based on the treatment of migraine and the efficacy remains to be clarified.
