Summary

A tonic–clonic seizure during pregnancy causes significant redistribution of maternal blood circulation, provokes uterine contractions, and develops transient maternal lactic acidosis that is transferred to her fetus through the placenta. Despite these extensive and significant alterations in pathophysiology, no association has yet been verified in the modern literature between seizures and pregnancy complications such as spontaneous abortions, fetal malformations, growth retardation, stillbirths, preterm delivery, or placental abruption. Thus, a healthy fetus seems to tolerate maternal seizures reasonably well. However, none of the currently available studies have sufficient power to reliably exclude harmful effects of seizures on the pregnant woman or on her fetus. It is therefore prudent to strive to reduce the risk of seizures to a minimum during pregnancy.
