Evaluations for balance disorders
40% of adults experience dizziness severe enough to report to their doctors. In the majority of patients, balance disorders can be helped if they receive the proper diagnosis and management. New theories in treatment have created options other than "learning to live with it". Diagnosing dizziness is a process that usually involves several tests. It starts with a detailed medical history and physical examination. The first test is usually a hearing test to determine if the inner ear has been affected in any way. The primary test for determining inner ear vestibular function is Electronystagmography (ENG) or Videonystagmography (VNG), depending on how data is collected. The ENG/VNG is a series of non-invasive computerized tests to evaluate the transmission of information by the individual components of the balance system. The entire test may take up to one and a half hours.
