[Diagnostic contribution of auditory and somesthetic evoked potentials in multiple sclerosis].

Results of BERA measured on 52 patients with possible Multiple Sclerosis were compared with the diagnosis pronounced one year after the initial functional exploration. In 21 of these patients, somesthetic evoked potentials were recorded at the same time as the BERA. One year later, diagnosis was considered as likely in 23 cases, as eliminated in 15 cases, and still possible in 14 cases. 38 cases were kept after elimination of the group with "possible diagnosis"; in 68.5% of them, an agreement was found between the results of initially recorded BERA and the diagnosis pronounced one year later. A parallel study of the correlation carried out in 16 patients, for whom somesthetic evoked potentials were recorded, showed a diagnosis agreement in 69% of the cases.
