Abstract
Clinical and spectral analyses of EEG recorded in the first trimester of pregnancy and six to nine months postpartum were performed in 11 women. It was shown that, in all examined women, the spectral power of virtually all rhythms of baseline postpartum EEG was uniquely decreased compared to the EEG during pregnancy in all derivations. To a lesser extent, this was characteristic of the β2 rhythm. Changes in the postpartum EEG were most manifest during hyperventilation, predominantly, in the form of burst and paroxysmal activity. The women were divided into groups with and without postpartum paroxysmal activity. It was observed that abnormal pregnancy was more frequent in women with burst EEG activity in the nopregnant state. This index can be used as a test to reveal the group of risk of unfavorable course of pregnancy.
