Examination of evoked potentials can be a useful diagnostic tool in the diagnosis and evaluation of patients with Multiple Sclerosis (MS). A description of the most frequently used EPs is given: BAEP, checkerboard VEP and short latency median nerve SSEP, together with an impression of their sensitivity. It is obvious that more clinical trials are necessary to evaluate also the other EP modalities before a balanced conclusion about the usefulness of EPs in MS can be formulated.
