It is estimated that 90 percent of babies born to women with epilepsy are normal and healthy. But pregnancy can cause a variety of challenges for women with epilepsy, including changes in seizure frequency and severity, as well as hormonal changes and vitamin deficiencies. Labor and delivery may also increase the risk for seizure and complications, although these problems are rare. Once the baby is born, women with epilepsy face several areas of concern, including breastfeeding and sleep deprivation as well as seizures that can put both the baby and the mother at risk of injury.
