癫痫是一组综合征,其特征为反复发作的大脑神经细胞异常放电所致的大脑功能失调。在临床脑电图检查中,我们观察到癫痫发作间歇期脑电图对癫痫的辅助诊断以及了解脑功能的损伤程度有很重要的价值。1 临床资料1.1 本组共200例,其中男120例,女80例,年龄1～20岁140例,21～40岁60例。发病时间1～5年68例,5～10年73例,10～20年39岁,20年以上20 Epilepsy is a group of syndromes characterized by brain dysfunction caused by recurrent abnormal firing of brain nerve cells. In the clinical EEG examination, we observed that the interictal epileptic seizure of epilepsy assisted diagnosis and understanding of the extent of damage to brain function has a very important value. 1 Clinical data 1.1 The group of 200 cases, including 120 males and 80 females, aged 1 to 20 years in 140 cases, 21 to 40 years old in 60 cases.
