An evoked potentials test is used to measure the brain’s electrical activity in response to sound, sight, or touch stimulus. Electrodes are used to detect your brain’s activity. There are three different types of evoked potentials tests that may be used:
- VER- Visual Evoked Response Test
- BAER- Brainstem Auditory Evoked Response Test
- SSER- Somatosensory Evoked Response Test
An evoked potentials test may be used to assess brain function, help diagnose multiple sclerosis, test hearing, test sight, or check for tumors. Because electrodes will be used, be sure to wash your hair before your procedure, and avoid applying product. Electrodes will record brain activity throughout for your doctor to interpret.
Evoked potentials tests are typically done on an outpatient basis with minimal side effects.
