Tests For Diagnosing Vestibular Disorders
The inner ear’s vestibular organs and the associated nerves and brain centers form a complex system that serves many functions and can be affected by a number of outside systems. A thorough evaluation of the inner ear may therefore require several different kinds of tests.
Doctors use information from a person’s medical history and findings from a physical examination as a basis for ordering diagnostic tests to assess the vestibular system function and to rule out alternative causes of symptoms. Most people tolerate these tests well. However, sometimes the tests are fatiguing and can result in temporary unsteadiness.
Some diagnostic tests may include:
– Electro/Video-nystagmomography (ENG/VNG)
– Rotation tests
– Video Head Impulse Test (vHIT)
– Vestibular Evoked Myogenic Potentials (VEMP)
– Computerized Dynamic Posturography (CDP)
– Audiometry (hearing tests)
– Otoacoustic Emission (OAE)
– Electrocochleography (ECog)
– Auditory Brainstem Response Test (ABR)
– Magnetic Resonance Imaging (MRI)
– Computerized Axial Tomography (CAT/CT)
– Other tests may include blood work, allergy tests, and vision tests
