Abstract : Vestibular migraine (VM) is a disorder where vestibular symptoms are causally related to migraine. It is one of the common causes of recurrent vertigo in the general population. It has often remained as an under-recognized condition with largely unknown pathophysiology. Accurate diagnosis is essential in vestibular pathologies as it determines the management in each case. The aim of this reasearch was to compare vestibular functions of patients with VM and healthy controls using VNG and to study the VNG patterns of patients diagnosed with VM. This study is a retrospective analysis of subjects who have undergone videonystagmography (VNG) testing from October 2018 to October 2020 done in a tertiary referral hospital. Those patients satisfying diagnostic criteria for vestibular migraine were subjected to VNG testing. Group 1 consisted of 35 vestibular migraine patients, and group 2 consisted of 35 age and sex-matched healthy controls. Statistical comparison of parameters of these groups were made.We found that the mean age of VM patients in the study was 40 ± 9.9, and the females were predominantly affected (Female: Male = 2.8:1). Statistically significant difference was obtained between VM patients and healthy controls in vertical smooth pursuit and in the positional tests using the Dix Hallpike test on the right side (p value < 0.05). We conclude that a careful study of VNG patterns can serve as a valuable tool in hard to diagnose cases of vestibular migraine.
