Just out of embargo (from Cochrane): A conclusion from looking at 28 studies was that use of sodium valproate during pregnancy to control epilepsy–I realize dosage may be different from what is prescribed for vestibular migraine–affected the fetus such that children showed lower Developmental Quotient and children lower Intelligence Quotient. Read as a Wiley release. I haven’t looked at the study itself:
