Corrective catch-up saccades triggered during or after a HIT usually indicate peripheral vestibular hypofunction; whereas normal clinical (bedside) HIT findings in acute vestibular syndromes suggest a central cause. Recent quantitative studies evaluating HITs using magnetic search coils or video-based techniques have demonstrated specific abnormal HIT patterns associated with central vestibular disorders. Improved identification of abnormal HIT patterns may help practitioners localize lesions responsible for central and peripheral vestibulopathies.

These manifestations occur in 4–67% of patients and can mimic peripheral vestibular disorders, making diagnosis challenging. Lesions affecting central vestibular and cerebellar pathways account for three main clinical presentations: acute vestibular syndrome, positional vertigo, and chronic imbalance. Distinguishing central from peripheral causes is crucial for accurate diagnosis. Videonystagmography and the video head impulse test enhance diagnostic precision. This chapter reviews the neurotological features of multiple sclerosis (MS) and underscores the role of vestibular testing in clinical evaluation and patient management.
