Evoked Potential Testing in MS

Multiple sclerosis (MS) is a complex demyelinating disease of the central nervous system for which there is no single diagnostic test. Common tools used to diagnose MS include the neurological exam, complete medical history, magnetic resonance imaging (MRI), and evoked potential (EP) studies.

What are evoked potentials?

As the brain “talks” to various parts of the body, messages are sent as electrical signals that travel along nerves. Demyelination and neurodegeneration caused by MS can disrupt these electrical signals. Evoked potential studies, also called evoked potentials (EPs), measure signals that travel through specific sensory nerve pathways in response to external stimuli. Those electrical signals are measured through sensors placed on the skin in combination with sophisticated computer programs.
