The etiology of vestibular neuritis is not completely clear; however, since patients tend to have symptoms of upper respiratory tract infections prior to the onset of the disease, it is believed that the etiology of the disease is related to viral infections, and other possible etiologies include bacterial infections, vascular degeneration, and diabetes. The basic etiologies are as follows: i. Injury to the human vestibular area. That is, when the vestibular nerve is damaged, the transmission of information cannot be carried out properly, and a series of symptoms such as vertigo will be manifested. Second, the predisposing factors are infections. At present, it is generally believed that the disease is related to viral infection of the vestibular nerve, but there are also studies showing that in a few cases it is related to bacterial infection. Patients mostly experience upper respiratory tract viral infection two weeks before the onset of the disease, which is the most common predisposing factor. Third, vascular lesions. Because of vestibular microcirculation disorders, it may lead to the development of the disease.
