The dissociation between pathological caloric testing and a normal video head impulse test can differentiate between Meniere disease (MD) and vestibular migraine (VM), according to a study. Vergil Mavrodiev and colleagues examined the sensitivity, specificity, and positive and negative predictive values (PPV and NPV) of the dissociation between a normal/pseudo-normal video head impulse test and reduced caloric testing to differentiate between MD and VM in a retrospective analysis of 2,101 patients. The examination group included 1,100 patients: 57 and 43% had MD and VM, respectively. The comparison group included 1,001 patients with other peripheral, central, or functional vestibular disorders.
