What is spared by fetal brain-sparing? Fetal circulatory redistribution and behavioral problems in the general population

Intrauterine growth restriction has been linked to infant behavioral problems. While typically only birth weight is examined, here the authors assessed fetal circulatory redistribution, also called the "brain-sparing effect," which is a fetal adaptive reaction to placental insufficiency. They aimed to investigate whether fetal circulatory redistribution protects against behavioral problems. Within the Generation R Study (Rotterdam, the Netherlands, 2003-2007), fetal circulation variables for the umbilical artery and the middle and anterior cerebral arteries were assessed with Doppler ultrasoun...
