Tests and treatments
What is it?
It is a test that examines whether signals are conducted normally over the nerve pathways.
- A BERA (Brainstem Evoked Repose Audiometry) tests the pathways for hearing, which are closely related to the pathways responsible for balance.
- An MEP (Motor Evoked Potential) tests the motor pathways.
- An SSEP (Somato Sensory Evoked Potential) tests the sensory pathways.
- A VEP (Visual Evoked Potential) tests the visual pathways.
What is the process?
A staff member of the Neurology Department will place electrodes on your head, arm and/or leg. To do this, a type of gel and some tape will be used.
Then various stimuli will be given.
- BERA: sounds via headphones or earphones
- MEP: a special coil will be placed about your head and will emit a magnetic pulse
- SSEP: electrical shocks on the pulse or ankle
- VEP: looking at a checkerboard pattern on a screen
- BERA: tell staff if you wear a hearing aid.
- VEP: if you have glasses or contact lenses, do not remove them. You must be able to follow the stimulus on the screen.
