The diagnostic value of the pattern reversal evoked cortical potential (VEP) and the somatosensory evoked cortical potential (SEP) has been compared in 50 patients with established or suspected multiple sclerosis. A prolonged latency of VEP was found in 96% of definite cases of multiple sclerosis, 58% of probable cases, and 20% of possible cases. A prolonged latency of SEP by stimulation of median or peroneal nerves or both was found in 86% of definite cases of multiple sclerosis, 83% of probable cases, and 50% of possibe cases. When combining the results of all three tests the diagnostic yield increased to 100%, 92%, and 50%, respectively.
对50例确诊或疑似多发性硬化症患者的图形翻转诱发皮层电位(VEP)和体感诱发皮层电位(SEP)的诊断价值进行了比较。在96%的确诊多发性硬化症病例、58%的可能病例和20%的疑似病例中发现VEP潜伏期延长。通过刺激正中神经或腓总神经或两者,在86%的确诊多发性硬化症病例、83%的可能病例和50%的疑似病例中发现SEP潜伏期延长。当综合三项检查结果时,诊断阳性率分别提高到100%、92%和50%。
