Evoked potentials


Visual evoked potentials (VEPs) measure the electrical function of the optic nerve.

Somato-sensory evoked potentials (SSEPs) check the speed of nerve conduction from the limbs to the sensory cortex.

Both tests can be useful in the diagnosis of multiple sclerosis.

VEPs and SSEPs can demonstrate abnormal sensory function especially when the patient's health history or neurological examination are unreliable or equivocal.

They can show the presence of unsuspected malfunction in a sensory system when a demyelinating disease is suspected because of signs or symptoms elsewhere in the central nervous system (CNS).
