AB30 Acute vestibular syndrome

International Classification of Diseases for Mortality and Morbidity Statistics, 11th Revision, v2024-01

A clinical syndrome of acute-onset, continuous vertigo, dizziness, or unsteadiness lasting days to weeks, and generally including features suggestive of new, ongoing vestibular system dysfunction (e.g., vomiting, nystagmus, severe postural instability). There may also be symptoms or signs suggesting cochlear or central nervous system dysfunction. Acute vestibular syndrome usually connotes a single, monophasic event, often caused by a one-time disorder, but it may instead punctuate a relapsing-and-remitting or stepwise, progressive illness course. Disorders typically presenting this syndrome include vestibular neuritis, acute labyrinthitis, traumatic vestibulopathy, demyelinating disease with vestibular involvement, and strokes affecting central or peripheral vestibular structures.
