Antiepileptic drugs and cognition

Women with epilepsy who take more than one drug to control their seizures may have children who perform less well at school. Researchers from Karolinska University Hospital and the University of Lund in Sweden studied 1,308,318 children born between 1973 and 1986; 1,235 of them were born to mothers with epilepsy who took more-than-one (429), one (641) or no (165) anti-epileptic drugs when they were pregnant. Those children who had been exposed to more than one anti-epileptic drug in the womb had an increase risk of not receiving a final grade upon completion of their schooling. However, those whose mothers had taken only one kind of anti-epileptic drug showed no decrease in performance.
