With central causes of acute vestibular syndrome, it is not uncommon for the nystagmus to have a gaze-evoked component due to failure of gaze-holding circuits in the cerebellum or brainstem. In such instances, the nystagmus may reverse direction when the patient looks in the direction of the slow phase (Video 2b-direction-changing nystagmus; spontaneous left-beating nystagmus in primary and left gaze with reversal in right gaze in a patient with acute cerebellar infarction).
