We investigated the development of the background activity of EEGs in 150 children with epilepsy by means of computerized power spectral analysis, using Fourier transformation by O1 Twenty-seven cases with idiopathic generalized epilepsy (IGE), 30 cases with idiopathic partial epilepsy (IPE), 60 cases with symptomatic partial epilepsy (SPE), 33 cases with cryptogenic partial epilepsy (CPE) and 48 normal children were studied. The records with paroxysmal activity at 01 were excluded in this study. In normal children, total, delta and theta powers showed a significant inverse correlation with age, but alpha-2 and beta-2 powers showed a significant positive correlation with age. In children with epilepsy, there were significant increases of delta and theta powers and a decrease of alpha-2 power compared with normal children. The development of the EEGs was different among the patients with various types of the epileptic syndrome. It was suggested that age, prognosis and anticonvulsants were important factors which influence the EEGs background activity.
我们采用计算机化功率谱分析方法，通过傅里叶变换对150例癫痫患儿的脑电图背景活动发展情况进行了研究，研究对象包括27例特发性全身性癫痫（IGE）患儿、30例特发性局灶性癫痫（IPE）患儿、60例症状性局灶性癫痫（SPE）患儿、33例隐源性局灶性癫痫（CPE）患儿以及48名正常儿童。本研究排除了O1处有阵发性活动的记录。在正常儿童中，总功率、δ波功率和θ波功率与年龄呈显著负相关，而α2波功率和β2波功率与年龄呈显著正相关。与正常儿童相比，癫痫患儿的δ波功率和θ波功率显著增加，α2波功率降低。不同类型癫痫综合征患者的脑电图发展情况有所不同。研究表明，年龄、预后和抗惊厥药物是影响脑电图背景活动的重要因素。
