Vestibular neuritis (VN) is an acute vestibular syndrome after unilateral acute vestibular nerve injury. In recent years, the incidence and chronic degree of VN have increased significantly. Related studies have shown that the improvement of chronic symptoms in patients with VN is more the result of central compensation than the recovery of peripheral vestibular function.And the course of recovery may be related to vestibular perceptual function, psychological factors and visual dependence. The purpose of this study is to identify the predictive factors of "acute to chronic" dizziness in VN patients, and to put forward the viewpoint of early identification and intervention of the relevant factors affecting the long-term prognosis of VN patients, so as to make the high-risk VN patients who are easy to enter the chronic phase become the target of intensive treatment.
