The definition of brain death includes the irreversible loss of all brainstem and forebrain functions. The electroencephalogram (EEG), used to test forebrain functions, is part of the diagnostic armamentarium and is considered necessary even after primary infratentorial lesions. A review of both the current literature as well as new data on an interrater agreement and intrarater stability study provide the basis for a discussion on the reliability of EEG recording in this context and on the definition of brain death. Under normal conditions, the presence of an electrocerebrally inactive EEG is a valid indicator of brain death. However, the reliability and accordingly the validity of the EEG is restricted by technical problems and limited intrarater stability and interrater agreement.
脑死亡的定义包括所有脑干和前脑功能的不可逆丧失。用于测试前脑功能的脑电图（EEG）是诊断手段的一部分，即使在原发性幕下病变后也被认为是必要的。对当前文献以及关于评分者间一致性和评分者内稳定性研究的新数据进行综述，为讨论在此背景下脑电图记录的可靠性以及脑死亡的定义提供了基础。在正常情况下，脑电图显示大脑电活动消失是脑死亡的有效指标。然而，脑电图的可靠性以及相应的有效性受到技术问题、评分者内稳定性有限和评分者间一致性的限制。
