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.
