Characterisation of Cortical Vestibular Evoked Potentials (C-VEPs)
Vestibular Neuronitis
About this trial
This is an interventional diagnostic trial for Vestibular Neuronitis focused on measuring partial vestibular deficit, cortical vestibular evoked potential

- Over 18 years of age
- Can provide informed consent
- No previous otoneurological history
Exclusion Criteria:

Experimental
Active Comparator
vestibular deficit
otologically normal controll
Initial clinical assessment including otoneurological examination, pure tone audiometry, tympanometry vestibular screening tests and Magnetic Resonance Imaging as clinically indicated. The cortical vestibular evoked potentials will add approximately add an extra 30 minutes to the test sequence but is minimally invasive and will not cause any pain or discomfort. It will be conducted on both the affected and non-affected ears.
Normative data will be collected from 36 normal ears from subjects that have no history of audiovestibular symptoms and are not being investigated for any balance disorders. The cortical vestibular evoked potentials will be recorded from both ears
