Evoked potential tests (EP tests) measure how the brain responds to stimulation of specific nerve pathways in the body.
Technicians at Dignity Health Central California offer a range of EP tests, including VEP, BAEP, and SEP tests, to determine if you have nerve fiber damage or disease. For an evoked potential test in Bakersfield, CA, Find a Doctor at:
All EP tests measure electrical activity in the brain, which corresponds to how well your nerves send signals. Poor nerve signaling, or conduction, can indicate a neurological condition such as multiple sclerosis (MS), a tumor pressing on the spine or brain, or other disease.
The main types of evoked potential tests are:
Evoked potential tests are noninvasive. Your neurologist may ask you to have more than one type of EP test, which can be done at an outpatient center or in a hospital.
For an EP test, a technician will apply electrodes to your scalp and neck and, possibly, your arms or legs. These electrodes are painless. They send information to a nearby computer.
Electrodes on your scalp capture your brain’s electrical activity. The technician measures how long it takes for the stimulus to cause a response in your brain. Healthy nerves transmit signals almost instantly.
There is usually no recovery period after evoked potential testing. You likely can return to home or work immediately after the test.
Dignity Health Central California doctors use VEP, BAEP, and SEP tests to find the source of nerve-related symptoms. Your neurologist will discuss the results and next steps with you. These may include additional testing and a personalized treatment plan that considers your physical, mental, and spiritual needs.
