The electroencephalograms (EEGs) of epileptic women in late pregnancy were compared with their EEGs outside pregnancy and the puerperium. The number of epileptic interictal discharges was not modified by pregnancy. Visual scoring and frequency analysis demonstrated a slight increase in the alpha band during pregnancy. No correlations were found between the EEG findings and changes in seizure frequency.
