What Are Evoked Potential Studies?
EP studies are completely non-invasive and used to detect even small changes in how nerve pathways are working. These tests are especially helpful when symptoms are subtle or hard to explain.
We offer three main types of Evoked Potentials at CNS:
- Visual Evoked Potentials (VEP): Measures how your brain processes visual signals
- Brainstem Auditory Evoked Response (BAER): Evaluates hearing and brainstem function
- Somatosensory Evoked Potentials (SSEP): Measures nerve response to touch or mild electrical pulses in the arms or legs
Why You Might Need EP Testing
Evoked Potential testing may be recommended if you have:
- Vision problems or optic neuritis
- Hearing loss or unexplained ringing in the ears
- Numbness, tingling, or sensory changes
- Symptoms of multiple sclerosis (MS)
- Spinal cord injuries or compression
- Unexplained balance or coordination issues
EP studies help your doctor pinpoint where the problem is and what steps to take next.
What to Expect at Your Appointment
Your test will be done in a calm, comfortable setting. Here’s what you can expect:
- You’ll either sit in a chair or lie down, depending on the test.
- We’ll place small, painless electrodes on areas such as your scalp, earlobes, wrists, or behind the knees.
- You’ll receive gentle stimulation through light flashes, sound, or mild pulses on the skin.
- We’ll record how your nervous system responds.
The test typically lasts between 30 to 90 minutes. It’s safe, gentle, and there’s no downtime after your visit.
