Abstract:
Vestibular migraine(VM)is a common paroxysmal vertigo disease whose diagnosis is main-ly based on patient history and symptom characteristics.Vestibular function tests are commonly used to diag-nose vestibular and vertigo diseases,including electronystagmography,video head impulse test(vHIT),caloric test,audiometry,electrocochleography(EcochG),and vestibular-evoked myogenic potential(VEMP).Central positional nystagmus is the most common nystagmus in VM,which differs significantly from nystagmus in the plane of the affected semicircular canal in benign paroxysmal positional vertigo(BPPV).In vHIT examina-tion,the gain of VM patients is generally normal,but their small-amplitude saccades are more meaningful for disease screening and differentiation.The abnormal rate of caloric testing in VM ranges from 19.4%to 56.0%,and VM patients with abnormal caloric test results may have a poor prognosis.Hearing tests in VM patients are usually normal,while EcochG has good application value in differentiating VM from Meniere's disease(MD).Studies applying VEMP to VM show divergent or even contradictory results,and specific posi-tive manifestations remain unclear.Functional magnetic resonance imaging(fMRI)is an MRI method for studying brain neural activity,divided into task-state and resting-state modes,both of which can be applied to VM diagnosis.This article analyzes the application value of vestibular function tests and fMRI in the diagnosis and treatment of VM,providing support for research on both types of examinations in the management and prognosis of vestibular migraine.
