Abstract:Objective To evaluate vestibular function in patients with vestibular migraine by laboratory tests. Meth-ods Thirty-seven patients with vestibular migraine (VM) and 31 healthy volunteers completed caloric test, HNS, rotational test and VEMP, and the results were compared between the two groups. The asymmetry of cVEMP induced by 100 dB tone-pip stimuli was also compared between the two groups. Results The rate of abnormal horizontal semicircular canal function in the VM group was significantly higher than that in control subjects (P<0.05). Of the 37 VM patients, 11 (29.7%), 14 (37.8%) and 7 (18.9%) exhibited abnormal caloric, HSN, and rotational test results, respectively, in contrast to 2 (6.7%), 1 (3.3%) and 0 of the 30 healthy volunteers exhibiting corresponding abnormal results. Overall, 76% of patients with VM had abnormalities in at least one of the horizontal semicircular canal function tests, with the highest. abnormality rates seen in HSN, followed by rota-tional and the caloric tests. The rates of abnormal cVEMP in VM patients (21.6%) were significantly higher than those (3.3%) in the control group (P<0.05). Conclusions Most (76%) vestibular migraine patients have vestibular dysfunction. Detection of vestibular abnormality in patients with VM can be enhanced by adding HSN and rotational tests to caloric test. Patients with vestibular migraine may have abnormal function of the saccule and sacculocollic pathway damage as indicated by cVEMP. Ves-tibular dysfunction may be common among vestibular migraine patients to varying degrees.
