Study Notes
Videonystagmography (VNG)
- Defined as involuntary, rhythmic eye movements, which can be horizontal, vertical, or rotatory.
- Part of a comprehensive set of tests to assess vestibular function and balance.
Impact of Traumatic Brain Injury (TBI)
- TBI can trigger vestibular disorders such as Benign Paroxysmal Positional Vertigo (BPPV) or Ménière's disease.
- A significant percentage of TBI patients exhibit vestibular symptoms five years post-injury.
- Survivors of TBI show a threefold increase in unemployment rates, highlighting the long-term impact of such injuries.
VNG Test Utility
- Serves as an essential diagnostic tool in evaluating vestibular symptoms associated with TBI.
- Average duration of a VNG procedure varies, indicating the need for efficient assessment protocols.
Evaluation Protocol
- An ENT evaluation and a VNG test are standard procedures for all TBI patients, regardless of whether they present symptoms, ensuring comprehensive care.
Administration of VNG
- Can be performed by trained health professionals specializing in vestibular assessments, ensuring accurate diagnosis and management.
Gold Standard Testing
- The VNG test is recognized as the gold standard for assessing vestibular disorders, proving its reliability in clinical practice.
