Chinese Real-world Study of Treatment of Vestibular Migraine

Vestibular migraine is a phenotype of migraine, characterized by more prominent vertigo symptoms compared to headache. Treatments for VM are mainly divided into two categories: acute treatment and preventive treatment. Acute treatment aims to reduce the severity and duration of a single episode, while preventive treatment aims to decrease the frequency, severity, and duration of attacks. Current acute treatments are primarily divided into pain relief and anti-dizziness, with specific drugs such as triptans and ergots being applicable for pain relief, but only betahistine has weak evidence for anti-dizziness, and relevant clinical evidence is very scarce. Preventive treatment mainly refers to migraine preventive treatments, with recommended medications including traditional drugs like topiramate, flunarizine, propranolol, etc., but the efficacy and safety of these drugs are limited. CGRP-targeted drugs are believed to play a role in the preventive treatment of VM, and there are related literature reports, but most are small-sample studies or retrospective studies. This study aims to explore the real-world efficacy of CGRP-targeted drugs in the acute and preventive treatment of VM through a prospective real-world study.
