The lifetime prevalence of vertigo is about 7.4% and is one of the most common reasons for neurology visits. It has been found that some patients with recurrent vertigo cannot be explained by common diseases such as benign episodic positional vertigo (BPPV), Meniere’s disease, and posterior circulation ischemia, but their medical history suggests an association with migraine and a response to migrainous treatment. Recent researchers have proposed the concept of migrainous vertigo (MV), which links vertigo to migraine as a clinical syndrome rather than a specific disease as an etiologic relationship. Neuhauser et al. (Acta Otolaryngol, 2005, 125(11):1247-1248) proposed a more comprehensive concept of migrainous vertigo (MV), which was 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. Poor head movement tolerance a sense of imbalance or illusion of movement of self or surrounding objects due to head movement (severity of vestibular symptoms is classified as grade III: mild as not interfering with daily activities, moderate as interfering but not limiting daily activities, and severe as limiting daily activities); 1.2 Migraine that meets IHS criteria 1.3 At least two episodes of vertigo with one of the following migraine symptoms: migrainous headache, 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
