报告２４ｈ动态脑电图（ＡＥＥＧ）监测２１０例颅脑损伤病人脑电活动，其异常率为８５．２％，略高于文献报道的脑电图及脑电地形图的异常率。其中临床诊断为外伤性癫痫的３０例病人ＡＥＥＧ均异常，２５例有痫样放电（１２例出现于睡眠中）。因此，ＡＥＥＧ的昼夜记录对提高癫痫诊断的阳性率价值很大。１０８例ＣＴ异常的病例中，１０４例ＡＥＥＧ有异常，其阳性一致率为９６．３％；４５例ＣＴ正常中，３０例ＡＥＥＧ有异常，占６６．７％。所以，ＣＴ与ＡＥＥＧ在颅脑外伤诊断中各有所长，不能相互取代。
Reported 24 h dynamic electroencephalogram (AEEG) monitoring of 210 patients with brain injury in patients with brain electrical activity, the abnormal rate was 85.2%, slightly higher than the reported EEG and EEG abnormal rate. The AEEG of 30 patients clinically diagnosed as traumatic epilepsy were abnormal, and 25 patients had epileptiform discharges (12 in sleep). Therefore, diurnal recording of AEEG is of great value in raising the positive rate of diagnosis of epilepsy. In 108 CT abnormal cases, 104 cases of AEEG were abnormal, and the positive rate was 96.3%. Among 45 cases of CT normal, 30 cases had abnormal AEEG, accounting for 66.7%. Therefore, CT and AEEG have their own strengths in the diagnosis of traumatic brain injury, can not replace each other.
