We investigated the developmental features of the EEG-background activity of the 30 patients with benign childhood epilepsy. We found significant spectral differences between the benign childhood epilepsy group (BECCT; 25 cases, CEOP; 5 cases) and the normal control group. Compared with the normal group, the epilepsy group showed a shift of the spectrum to slower frequencies, with an increase in Delta and Theta, and a decrease in Alpha 2. The decrease in the mean frequency (O1) was significant from 8 years old to 10 years old. But in both the following periods; before 8 years old and after 10 years old, the difference was not significant. In the patients with benign childhood epilepsy, the development of the EEG-background activity came to be stagnant from 6 years old or so, and after 10 years old it developed again and approached to that of the normal children. It is suspected that the EEG background activity of children with benign partial epilepsy shows a special development.
我们研究了30例儿童良性癫痫患者脑电图背景活动的发育特征。我们发现良性儿童癫痫组（BECCT；25例，CEOP；5例）与正常对照组之间存在显著的频谱差异。与正常组相比，癫痫组频谱向低频转移，δ波和θ波增加，α2波减少。平均频率（O1）在8岁至10岁之间显著下降。但在接下来的两个时期，即8岁之前和10岁之后，差异均不显著。在儿童良性癫痫患者中，脑电图背景活动从6岁左右开始停滞，10岁之后再次发育并接近正常儿童。推测良性部分性癫痫患儿的脑电图背景活动呈现特殊的发育过程。
