Causes
Some patients will report having an upper respiratory infection (common cold) or a flu prior to the onset of the symptoms of vestibular neuronitis, others will have no viral symptoms prior to the vertigo attack.
Some cases of vestibular neuronitis are thought to be caused by an infection of the vestibular ganglion by the Herpes Simplex type 1 virus. However, the cause of this condition is not fully understood, and in fact many different viruses may be capable of infecting the vestibular nerve.
Acute localized ischemia of these structures also may be an important cause. Especially in children, vestibular neuritis may be preceded by symptoms of a common cold. However, the causative mechanism remains uncertain.
