[Laboratory and supplementary examinations in multiple sclerosis (a report of 32 cases)].

Laboratory and supplementary examinations were performed in 30 cases of definite multiple sclerosis (MS) and 2 cases of probable MS. The results showed that the visual evoked potential was the most sensitive way for demonstrating MS (76.9%), and the brain stem auditory evoked potential was the next (64.5%). The electroencephalograms were abnormal in 52.9%, the cerebrospinal fluid oligoclonal band positive in 50%, and the CT scans findings in 42%. Electrophysiological abnormal findings were parallel with MS changes. It was considered that electrophysiological examinations is a useful method for the diagnosis and monitoring of MS, as well as for the guidance in its clinical treatment.
