Rapid and undesired eye motion (nystagmus) often results from the improper indication of rotational motion. Nausea, anxiety, and a general ill feeling are common due to the distorted balance signals that the brain receives from the inner ear system. Other common symptoms include tinnitus, ear ache, and a feeling of fullness in the ear. Causes
Some people will report having an upper respiratory infection (common cold) or flu prior to the onset of the symptoms of vestibular neuritis; others will have no viral symptoms prior to the vertigo attack. Some cases of vestibular neuritis 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.This can also be brought on by pressure changes such as those experienced while flying or scuba diving. Mechanism
In the vestibular system, there are three canals that are semicircular in shape that input sensory clues. These canals allow the brain to sense rotational motion and linear motion changes. The brain then uses the sensory input clues and the visual input clues from the vestibular system to retain balance. The vestibulo–ocular reflex retains continuous visual focus during motion which is also the vestibular systems job during activity.
Mental disorders
Because mood disorders can hamper recovery from labyrinthitis, treatment may also include any co-occurring anxiety disorder or depression. Severe anxiety episodes are usually addressed by short-term benzodiazepine therapy. Prognosis
Recovery from acute labyrinthine inflammation generally takes from one to six weeks, but it is not uncommon for residual symptoms such as dysequilibrium and dizziness to last for a couple of months.Recovery from a temporary damaged inner ear typically follows two phases:

An acute period, which may include severe vertigo and vomiting
approximately two weeks of sub-acute symptoms and rapid recovery

Epidemiology
Labyrinthitis affects approximately 35 million people per year (approximately 3.5 cases per 100,000 people). It typically occurs in those between 30 and 60 years of age, and there are no significant differences between male and female incidence rates. In 95% of cases, sufferers experience a single attack and fully recover. Vestibular rehabilitation showed a statistically significant increase in controlling symptoms over no intervention in people who have vestibular neuritis. References
