Central Vestibular Disorder

What is Central Vestibular Disorder?


Central vestibular disorder describes dizziness, vertigo or imbalance that is result of dysfunction within the central nervous system. The central nervous system plays a large role in successfully processing balance and spatial information.


Central Vestibular Disorder Symptomology:


Symptoms of central vestibular disorder typically have a gradual onset and progression in severity. Dizziness associated with central vestibular disorder may be described as a feeling of disequilibrium, lightheadedness or general imbalance rather than vertigo. Furthermore, symptoms are typically described as constant rather than episodic.


Central Vestibular Disorder Testing:


Indications of a central lesion may be revealed during videonystagmography (VNG) testing. VNG central indications may include: abnormalities of eye movements, direction-changing nystagmus within one head position, or nystagmus exacerbated by visual fixation. This information can then be sent to patient’s referring physician for further investigation.
