Antiphospholipid antibodies may have an impact on neurodevelopment during fetal life. Although rare, persistence of these antibodies in the neonate may lead to thromboembolism, particularly if there is a concurrent infection and/or inherited thrombophilic disorders. Affected pregnant women need to be identified early during gestation so that they can have close monitoring of the placental circulation, fetal growth and development, and testing of serum antiphospholipid antibody levels. Neonates born to mothers with antiphospholipid antibody syndrome should have close neurodevelopment follow-up.
