Objective Vestibular migraine (VM) is a diagnostic challenge. Visually enhanced vestibulo-ocular reflex (VVOR) gain, measure of the visual–vestibular interaction, has been proposed as tool for diagnosing VM. This study seeks to evaluate VVOR gain's capability predict VM and compare phenotypes vestibular patients with elevated versus normal/low gain. Methods A retrospective review consecutive ad...

The vestibulo-ocular reflexes stabilize retinal images during head movements. While there is a wealth of information about the interaction between the cerebellum and vestibulo-ocular reflexes mediated by the semicircular canals, little is known about the role of the cerebellum in the generation of the otolith-mediated linear vestibulo-ocular reflex (LVOR). By means of transient linear accelerat...

UNLABELLED Migraine and vertigo are common disorders, with lifetime prevalences of 16% and 7% respectively, and co-morbidity around 3.2%. Vestibular syndromes and dizziness occur more frequently in migraine patients. We investigated bedside clinical signs indicative of vestibular dysfunction in migraineurs. OBJECTIVE To test the hypothesis that vestibulo-ocular reflex, vestibulo-spinal reflex...
