摘　　要：目的：研究脑ＣＴ检查为阴性的轻型颅脑损伤的脑电图（ＥＥＧ）、脑电地形图（ＢＥＡＭ）变化特点及其临床价值。方法：对近两年１０８例无ＣＴ影像学改变的轻型颅脑损伤进行早期动态ＥＥＧ和ＢＥＡＭ监测。结果：异常改变者达８８．８９％，其中７９．１７％为异常的θ波和δ波，伤后三天内测得的阳性率显著高于三天后（Ｐ＜０．０１），并发现脑生物电异常变化沿受力轴线分布。结论：早期反复测定ＥＥＧ、ＢＥＡＭ的变化是反映轻型脑损伤早期脑功能变化定位和伤情分析。Objective: A study of the changing characteristics and clinical value of EEG and BEAM of the negative minimal brain injury examined by CT. Methods: We have monitored the early changes with dynamic EEG and BEAM on 108 cases of minimal brain injury in the last tow years. Results: It has abnormal changes and its rate is 8889%. Among them 7917% has abnormal electrocephalographic wave θ and δ, the positive rate of EEG in the first three days after damage is obviously higher than that after 3 days ( P<0.01 ) and we discovered that there were cerebral bioelectricity changes at varying degree on all nurse tissue along the attack direction. Conclusions: The early changes of EEG and BEAM are an important objective criterion for us to locate the damage position, analyze the damage degree and make clinical diagnosis and therapeutic effect on minimal brain injury. 
