Analysis of electronystagmogram results in patients with vestibular migraine and posterior circulation infarction

Objective To compare and describe the characteristics of the VNG parameters of VM patients and PCI patients.Methods This was a cross-sectional study.PCI and VM patients who were admitted to the Department of Neurology of Beijing Tiantan Hospital,Capital Medical University from November 2018 to November 2019,were examined for VNG.Results The characteristics of VNG parameters were analyzed and compared.The abnormal rates of saccade,smooth pursuit,optokinetic test,gaze-evoked nystagmus,and spontaneous nystagmus in patients with PCI were significantly higher than patients with VM,while there was no significant difference in the rate of positional nystagmus;the two groups patients’positional nystagmus were induced in various positions,and the duration was more than 60 s.Conclusion The abnormal rate of optokinetic examination and spontaneous nystagmus of PCI patients was significantly higher than those in VM group.There was no significant difference in the abnormal rates of positional nystagmus.Video nystagmus may help distinguish the two diseases.
