Vestibular neuritis (also called vestibular neurononitis) is caused by viral infection of the vestibular nerve, which is the nerve that conveys balance information from the inner ear to the brain. The most common virus that causes vestibular neuritis is Herpes Simplex Virus type 1 (HSV-1), which is the same virus that causes cold sores. In an article by Schuknecht and Kitamura entitled "Vestibular Neuritis" (1981), the terms vestibular neuritis, vestibular neuronitis and epidemic vertigo were used synonymously. They defined this as a disorder of the vestibular system without an associated auditory deficit or other disease of the central nervous system (CNS). Look for signs of vestibular neuronitis.

The key signs and symptoms of vestibular neuritis are rotatory vertigo with an acute onset lasting several days, horizontal spontaneous nystagmus (with a rotational component) toward the unaffected Vestibular Neuritis and Other Unilateral Vestibulopathies.
