Neuhauser et al. (Acta Otolaryngol, 2005, 125(11):1247-1248) proposed a more comprehensive concept of migrainous vertigo (MV), which is accepted by most scholars. MV is divided into two categories: definite MV (definite migrmnous vertigo) and probable MV (probable migrainous vertigo). 1. Diagnostic criteria of definite MV 1.1 Moderate or severe episodic vestibular symptoms, including rotational vertigo, other self-motion illusions, positional vertigo. 1.2 Migraine that meets the criteria of IHS; 1.3 At least two episodes of vertigo with one of the following migraine symptoms: migrainous headache, photophobia, acoustophobia, visual acuity, and vertigo. photophobia, phonophobia, visual or other aura; 1. 4 Exclusion of other etiologies. 2. possible MV diagnostic criteria 2.1 moderate or severe episodic vestibular symptoms; 2.2 at least one of the following symptoms: migraine meeting IHS criteria, migrainous symptoms during a vertigo attack, migraine-specific vertigo triggers (e.g., specific foods, sleep irregularities, endocrine disorders), effective anti-migraine medication; 2.3 exclude other etiologies.
