Abstract
102 patients with multiple sclerosis (MS) have been investigated by one or more of the following techniques: visual evoked potentials, cervical and cortical somatosensory evoked potentials, horizontal saccadic eye movement velocities, and computerised axial tomography of the cranium and orbits. It has been found that with each technique it is possible to detect abnormalities, which may be subclinical, in a significant proportion of patients. The proportion with abnormal results was greater in patients studied by more than 1 technique and was greatest in those patients who were studied by each of the 5 techniques. It is concluded that the techniques used have a complementary role in the investigation of patients suspected of having MS.
