Investigation
Identification
Because other conditions can result in vertigo, including certain brain conditions, your physician will probably wish to perform certain tests to identify the cause of your veritgo. One such test is known as the Dix-Hallpike test, or less commonly the Nylen-Barany test. this will allow your physician to identify whether the cause of vertigo is central (caused by the brain) or peripheral (caused by the sensory tools of the body, such as the labyrinth). Using these test and others, your physician may correctly identify the cause of the vertigo and prescribe treatment accordingly.
Nystagmus
TAnother symptom includes an involuntary twitching movement of the eye, called Nystagmus. This is not the same as a twitch of the eyelid, which is quite common. The feeling of vertigo, in which the world is moving when in fact it is stationary, is probably the most commonly reported symptom. However, it may be exacerbated by rapid movement of the head, even some weeks after the infection has cleared. Also, hearing loss (whether temporary or permanent), could be a (rarer) effect of the condition, and hearing exams should accompany a diagnosis.
Additional Diagnosis
Additional diagnosis of Labyrinthitis are based on a combination of the patient's symptoms and history- especially where there is a history of a recent upper respiratory infection. Your doctor can test your hearing, and order a laboratory culture to help identify the organism if the patient has a discharge. If there is no history of a recent infection, the doctor can arrange additional tests in order to exclude injuries to the brain or Meniere's disease.
