“…Positron emission tomography (PET) and blood oxygenation level dependent functional magnetic resonance (fMR) studies have shown structural and functional changes in brain areas responsible for central vestibular control and vestibular compensation in patients with VM 21 . Vestibular findings are thought to be explained by a wave of depression that spreads from the occipital lobe to the cerebral cortex 1 .…”

SUMMARY Objective The aim of this study is to evaluate vestibular functions with video head impulse test (VHIT) and to understand the value of VHIT in differential diagnosis in patients with vestibular migraine (VM) during dizziness attack. Materials and methods Two groups were enrolled in this study. The first consisted of 84 vestibular migraine patients, and second group of 74 healthy subjects. VHIT was applied to patients with VM during vertigo attack and the results were compared with the VHIT values applied to subjects in the control group. Results The mean vestibulo-ocular reflex (VOR) in all semicircular canals in the VM group was lower than healthy individuals, but the results were not statistically significant. Refixation saccades were found in 52.3% of VM patients and in 10.2% of healthy individuals. Conclusions When patients with VM were evaluated with VHIT during vertiginous attack, VOR gain values were not different from healthy individuals, but the number of catch-up saccades were higher in VM patients, which indicates peripheral vestibular involvement. For differential diagnosis in patients with VM, vestibular tests should be performed during the vertigo attack. When evaluating VHIT results, the presence of refixation saccades should also be evaluated.

Paroxysmal positional vertigo is a frequent cause for consultation. When approaching these patients, we try to differentiate central from peripheral causes, but sometimes we find manifestations that generate diagnostic doubts. In this review, we address atypical paroxysmal positional vertigo, reviewing the literature on the subject and giving a provisional definition of atypical positional vertigo as well as outlining its causes and pathophysiological mechanisms.
