    Abstract:
    Till now there are no specific laboratory tests to confirm the diagnosis of Multiple Sclerosis (MS). For this reason the diagnosis of MS is based on the clinical evidence of central nervous system white matter disease with temporal and spatial dissemination of the lesions. Recent advances in neurophysiology and imaging techniques can provide more objective criteria towards more accurate and earlier diagnosis, detecting clinically unsuspected lesions. We evaluated 39 MS patients (23 definite, 7 probable, 9 possible) by Magnetic Resonance Imaging (MRI), CT scan, Evoked Potentials (EPs) testing and Cerebrospinal Fluid analysis. MRI was abnormal in 34 cases (87%) and CT scan in 14 (36%); EPs were also abnormal in 34 cases. 30 patients had both EPs and MRI alterated and 4 patients had alterated only one of the two investigations. The frequency of EPs alterations was: VEP 74%, Median SEP 44%, Tibial SEP 59% and BAEP 54%. The BAEP was more sensitive than MRI in detecting brainstem involvement. On the other hand MRI was more sensitive than SEPs in detecting somatosensory pathways involvement. The combined use of the two techniques allowed a reclassification of 10 out of 16 possible or probable MS cases.
