Labyrinthitis and vestibular neuritis are conditions caused by an infection that incites the inner ear or the nerves that link the inner ear to the brain. This inflammation interferes with sensory information transmission from the ear to the brain. Vertigo, dizziness, and problems with coordination, sight, or hearing may occur as a consequence.
Infections of the inner ear are most typically caused by viruses; bacterial infections are less common. These inner ear diseases are not the same as middle ear diseases, which are bacterial infections that affect the region surrounding the eardrum and are more frequent in children.
