Abstract
Most pregnant women with epilepsy need pharmacological treatment during pregnancy. Children exposed to antiepileptic drugs have an increased risk of being born with major malformations. Some antiepileptic drugs seem to have negative effects on psychomotor or cognitive development in children exposed during foetal life. Neither carbamazepine nor lamotrigine in monotherapy seem to affect the cognition of exposed children. Several studies have shown negative effects on the long-term neurodevelopment of children prenatally exposed to valproic acid or polytherapy (two or more antiepileptic drugs during pregnancy). For most of the newer antiepileptic drugs there are insufficient data regarding long-term outcome.
