Development of EEG background activity in children with benign partial epilepsy.
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.
