Uses. Doctors often use evoked potential tests to confirm a diagnosis or monitor the nervous system, rather than to determine the cause of a slow reaction. MRI scans and tests of cerebrospinal fluid are the main ways of diagnosing MS nowadays.

What are evoked potentials used for?

Evoked potentials are used to measure the electrical activity in certain areas of the brain and spinal cord. Electrical activity is produced by stimulation of specific sensory nerve pathways. These tests are used in combination with other diagnostic tests to assist in the diagnosis of neurological disorders.

What is meant by evoked response?

An evoked potential or evoked response is an electrical potential recorded from the nervous system of a human or animal following presentation of a stimulus, as distinct from spontaneous potentials as detected by EEG, electromyography (EMG), or other electrophysiological recording methods.
