This paper presents diagnostic criteria for Menière’s disease (MD) developed by a collaborative effort involving multiple international societies and expert committees. The criteria are categorized into two types: definite MD and probable MD. Definite MD is diagnosed based on clinical criteria, including two or more episodes of vertigo lasting 20 minutes to 12 hours, audiometrically documented low- to medium-frequency sensorineural hearing loss in one ear, fluctuating aural symptoms (hearing, tinnitus, or fullness), and exclusion of other vestibular diagnoses. Probable MD is defined by similar criteria but with a broader duration of vertigo episodes (20 minutes to 24 hours). The paper also discusses the epidemiology, endolymphatic hydrops, familial MD, overlap with vestibular migraine, autoimmune inner ear disease, and differential diagnoses such as transient ischemic attack and stroke. The criteria aim to improve the precision of MD diagnosis and facilitate collaborative research.This paper presents diagnostic criteria for Menière’s disease (MD) developed by a collaborative effort involving multiple international societies and expert committees.
