A diagnostic tool, evoked potential tests, involve the placement of electrodes on the head and body. Response is recorded to determine where delays in nerve transmission occur. The visual evoked potential (VEP) test measures response to repeated visual stimuli to detect optic neuritis. The brainstem auditory evoked potential (BAEP) test detects abnormalities in the brainstem, which cause delays in the transmission of sound. The somatosensory evoked potential (SSEP) test delivers brief electrical stimulus to the wrist or ankle, in order to detect disruptions in the pathways from the arms and legs to the brain at very specific positions in the central nervous system (CNS).
