肝性脑病是肝硬化合并症之一,传统分为四期(Ⅰ～Ⅳ)。近年来人们逐渐认识到有相当多的患者虽存有代谢系统、脑机能障碍。却并无肝性脑病的临床症状,这种临床上缺乏症状。常规精神和神经功能检查正常,但智能或心理计量测验异常的肝病患者称为亚临床肝性脑病(SHE)。Gitlin等报道晚期肝硬化患者中60％～70％有这种SHE。我们对46例无精神或意识障碍,常规精神和神经功能检查正常的失代偿期肝硬化患者进行血氨智能测验(数字顺序联结试验NCT)、EEG、VEPs测定,并随访半年。结果报道于下。临床资料
Hepatic encephalopathy is one of the complications of cirrhosis, the traditional is divided into four (Ⅰ ~ Ⅳ). In recent years, people have come to realize that quite a few patients have metabolic disorders and brain dysfunction.

We evaluated 46 patients with decompensated cirrhosis who had no mental retardation, unconsciousness, normal mental function and normal neurological function, and measured the EEG and VEPs for six months. Results are reported below. clinical information
