Answer

Its etiology remains largely unknown, yet vestibular neuronitis appears to be a sudden disruption of afferent neuronal input from 1 of the 2 vestibular apparatuses. This imbalance in vestibular neurologic input to the central nervous system (CNS) causes symptoms of vertigo. At least some cases are thought to be due to reactivation of latent herpes simplex virus type 1 in the vestibular ganglia.
