Rotatorisk Vertigo - Praveen Ojha Gallery [2021]

Vestibular neuritis is a self‐limited otological condition. Patients present with vertigo, nausea, ataxia, and nystagmus. Most cases of vestibular neuritis are monophasic. Hearing is not impaired, and when there are similar symptoms with abnormal hearing, the syndrome is termed labyrinthitis. 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.
