Vestibulo-ocular reflex assessed with Video Head Impulse Test in children with Vestibular Migraine: Our experience

Abstract

Vestibular Migraine in children can mimic other disorders, especially at presentation. Outcome is hard to predict and management may be challenging due to the fact that many of the patients are too young to describe their symptoms and these are not always accompanied by headache. Objective: To assess vestibulo-ocular reflex (VOR) in pediatric patients who meet criteria for defined Vestibular Migraine and to compare results to healthy controls. Methods: Twenty-one patients aged 11-16 years were included in this prospective multicentric study. VOR was assessed using the video Head Impulse Test by EyeSeeCam (R)(Interacoustics, Denmark). Results: Patients with Vestibular Migraine (VM) have higher values of gain compared to asymptomatic patients. Conclusion: Video Head Impulse Test (vHIT) is a useful and relatively fast-to-perform examination in children compared to other vestibular tests. Patients with VM seem to have higher values of gain at vHIT.
