ICD-11 AB32 — Chronic vestibular syndrome
A clinical syndrome of chronic vertigo, dizziness, or unsteadiness lasting months to years and generally including features suggestive of persistent vestibular system dysfunction (e.g., oscillopsia, nystagmus, gait unsteadiness). There may also be symptoms or signs suggesting cochlear or central nervous system dysfunction. Chronic vestibular syndrome often connotes a progressive, deteriorating course, but sometimes instead reflects a stable, incomplete recovery after an acute vestibular event, or persistent, lingering symptoms between episodic vestibular events.
