Mechanisms involved in anticonvulsive effect of pregnancy in an animal model of epilepsy

Interrelation between pregnancy and epilepsy is one of the pressing problems of current neurology. Those mechanisms, which suppress or amplify the seizure reactions in pregnancy, have not been yet determined experimentally. Investigation of the interrelation between the epileptic fits and pregnancy in women is complicated by the bioethical considerations, as well as by the antiepileptic therapy. Therefore, in order to solve this problem, an implementing the animal models seems expedient; moreover that this problem is scarcely investigated so far. The goal of present work was investigation of impact of gestation and the postpartum period on initiation and development of convulsive reactions in the experimental animal model. Epileptic reactions were significantly suppressed during gestation (2 and 3 weeks). The data on the changes are concerned behavioral reactions and EEG seizure activity. Therefore, generalization of the seizure activity is blocked during pregnancy.
