Analysis of Vestibular Evoked Myogenic potentials in Migraines individuals attending a Tertiary Care Hospital

Abstract

Introduction:Migraine is a neurologic disease, often associated with a unilateral throbbing pain, which is categorized under primary headache disorder according to the International headache society (ICHS-3) beta edition. Migraine is the 3rd most prevalent illness and also the 6th most disabling illness in the world. Female: Male ratio: (3:1). Vestibular dysfunctions are frequently associated with migraine including the common type.

Material and method:

The cross observational study was done among the patients who had migraine in Chettinad super speciality hospital, kelambakkam over my study period. Participants who fulfill the international classification of Headache Disorders criteria were recruited from the Neurology OPD. Subjects are enquired about their history of diagnosis, Family history, Investigations and diagnostic tests such as cVEMP

Results:Prolonged latencies are likely due to the degradation of central vestibular processing of otolith signals rather than a decline in  peripheral vestibular function . VEMP amplitudes can be used as independent quantitative measures of otolith function. Several studies have reported that Abnormal VEMP potentials and Amplitude asymmetry are seen in Migranious individuals. Even though migraine is not an inner ear disorder, but of the brain, generally lower threshold is noted in migraine individuals. Conclusion:Migraine have very few available diagnostic tests with less statistical significance, VEMP studies on migraine patients may shed new light on its pathophysiology as well as only p13 and amplitude were considered .N23 0r N1 potential was used for only identifying p13.
