[Neurophysiological tests in the diagnosis of multiple sclerosis. Visual and somatosensory evoked potential studies].
Visual evoked potentials were recorded and found abnormal in 44 out of 57 multiple sclerosis (M.S.) patients (77%). Somatosensory evoked potentials were abnormal in 42 cases (73%). Both tests were abnormal in 56 out of 57 cases. The two tests have a complementary role in the assessment of M.S., showing a subclinical involvement of visual or sensory pathways in many cases. The high incidence of abnormal responses in patients with a short duration of the disease and in patients diagnosed as possible or probably M.S. suggests the aid of the tests in diagnosis of M.S.
