Abstract The teratogenic potential of valproate in pregnancy is well established; however, evidence regarding the long-term safety other antiseizure medications (ASMs) during remains limited. Using routinely collected primary care data from UK and nationwide Swedish registries to create a cohort 3,182,773 children, which 17,495 were exposed ASMs pregnancy, we show that those more likely receive diagnosis autism, intellectual disability, ADHD, when compared children not ASMs. Additionally,...

Background Intrahepatic cholestasis of pregnancy (ICP) is the most common obstetric liver disorder and associated with an increased risk iatrogenic preterm birth adverse infant outcomes. Hence, there are several plausible pathways through which ICP could affect offspring neurodevelopment. However, to best our knowledge, no studies have investigated these associations. Thus, we aimed determine whether neurodevelopmental conditions. Methods findings In this Swedish register-based cohort study,...
