Abstract
BACKGROUND: Abnormal vestibular function has been reported in patients with vestibular migraine (VM). However, it is unclear whether the proportion of patients with vestibular dysfunction differs between the diagnoses of VM and probable VM (PVM). METHODS: We reviewed the medical records of 1736 patients who underwent cervical vestibular-evoked myogenic potential testing to air-conducted sound (ACS cVEMP), ocular VEMP testing to bone-conducted vibration (BCV oVEMP), and caloric testing. We used the diagnostic criteria for VM provided in the appendix of the International Classification of Headache Disorders 3 Beta, and the diagnostic criteria consensus published by the Barany Society and the International Headache Society for PVM. Twenty-two VM patients and a further 22 PVM patients were included. Binomial logistic regression analyses were performed to see whether the subjects' age, sex, or the diagnostic certainty of VM (i.e., VM vs. PVM) have an association with the presence of vestibular dysfunction. RESULTS: There was no significant association between the diagnostic certainty of VM and abnormality in caloric or ACS cVEMP testing. On the other hand, VM had a significant positive association with abnormality in BCV oVEMPs compared with PVM. CONCLUSION: VM is associated with dysfunction of the utriculo-ocular pathway more frequently than PVM, suggesting that the pathophysiology of VM involves the utriculo-ocular pathway.
