Abstract

Middle latency auditory evoked potentials (MLAEPs) were studied in 30 definite multiple sclerosis (MS) patients in addition to brain-stem auditory evoked potentials (BAEPs). BAEP abnormalities were detected in 18 (60%) patients. MLAEPs were abnormal in 22 (73%) of them. In 15 patients BAEPs and MLAEPs were both abnormal. MLAEPs were found abnormal in 7 of the 12 patients with normal BAEPs. In 18 patients with abnormal BAEPs only 3 had normal MLAEPs. MLAEPs abnormalities are consistent with a rostral auditory pathway involvement. Therefore, they can be used in combination with BAEPs to examine the whole auditory system to improve the sensitivity.

摘要

除了脑干听觉诱发电位（BAEP）外，还对30例明确的多发性硬化症（MS）患者进行了中潜伏期听觉诱发电位（MLAEP）研究。18例（60%）患者检测到BAEP异常。其中22例（73%）MLAEP异常。15例患者BAEP和MLAEP均异常。12例BAEP正常的患者中有7例MLAEP异常。在18例BAEP异常的患者中，只有3例MLAEP正常。MLAEP异常与听觉传导通路头端受累一致。因此，它们可与BAEP联合使用，以检查整个听觉系统，提高敏感性。
