[Value of multimodal evoked potentials in the diagnosis of multiple sclerosis]

94 Patients diagnosed as having multiple sclerosis (MS) were examined by multimodal evoked potentials. According to the criteria of Bauer and Poser the patients were classified as possible, probable and certain forms of MS. Abnormalities were found in the VEP in 82.6% of cases (possible - 44.4%, probable - 87.5%, certain - 95.2%), in the BAEP in 51.3% of cases (possible - 27.3%, probable - 46.2%, certain - 68.8%) and in the SSEP in 71.1% of cases (possible - 35.3%, probable - 67.7%, certain - 88.1%). Subclinical lesions were detected by VEP in 37.0% of cases, by BAEP in 43.6% and by SSEP in 21.1%. Reclassification according to the results of the evoked potentials studies was required in 21.2% of cases. The value of evoked potentials in the diagnosis of MS is discussed with regard to the different forms of evoked potentials, as well as in comparison with other examination techniques.
