【摘要】 为了探讨亚临床肝性脑病（ＳＨＥ）的诊断问题，对２０例住院和门诊的肝硬化患者进行了脑电活动地形图（ＢＥＡＭ），脑诱发电位（ＶＥＰ－Ｐ，ＢＡＥＰ，ＳＥＰ）和韦氏成套记忆测验的综合检查．结果显示，上述检查均有不同程度的某项或多项结果异常．其中一项检测指标异常可视为ＳＨＥ；检测异常指标越多提示ＳＨＥ程度越重；多项检测指标全部异常，常提示重度ＳＨＥ，可预示这类病人不论有无诱因，近期可随时发生临床肝性脑病．在ＳＨＥ的３项检测方法中，脑诱发电位可为ＳＨＥ的首选和重要检测手段，ＢＥＡＭ也不失为诊断本病的重要方法．同时有必要考虑ＳＨＥ的诊断应采用多指标联合检测．更多还原

【Abstract】 In order to study diagnostic problems of subclinical hepatic encephalopathy（SHE），20 cirrhosis patients (in-patients and outpatients) were examined comprehensively with brain electrical activity mapping（BEAM），brain evoked potentials［visual evoked potential（VEP），brain-stem auditory evoked potentials（BAEP）and somatosensory evoked potential （SEP ） ］and wechsler memory scale（WMS）．The result were， in various degree，abnormal of one or multiple items，It was thought that a combined multi-index test should be adopted in SHE diagnosis．SHE could be recognized when one of the testing index was abnormal．The more abnormal indexes we found，the more serious SHE was thought．Multiple abnormal indexes often indicated serous SHE．whether there was any inducing cause or not，it could be predicted that recently SHE might occur in such kind of patients at any time， Of three SHE testing methods，brain evoked potentials could be regarded as a first－selected and important means in diagnosing SHE， and so could be BEAM．更多还原
