Testing for MS – Evoked potentials test
Language
Description
An Evoked Potentials Test help doctors understand how quickly messages travel along your nerves. These tests can be a useful tool for diagnosing multiple sclerosis particularly at the earlier stages of MS before symptoms appear. Your brain generates electrical currents when processing information from your senses. Evoked potential tests measure the time it takes for your brain to receive signals from the eyes, ears and skin. If MS has damaged myelin, the protective coating around your nerves, messages from your nerves may travel more slowly.
