In an analysis of more than 300,000 mother-child pairs, children of mom's who were taking an antipsychotic during pregnancy showed no increased risk for developing attention deficit-hyperactivity disorder (ADHD; weighted HR 1.16, 95% CI 0.83-1.61) or autism spectrum disorder (wHR 1.06, 95% CI 0.70-1.60), or of being born small for gestational age (wOR 1.36, 95% CI 0.86-2.14), reported Kenneth Man, PhD, of University College London School of Pharmacy, and colleagues in JAMA Internal Medicine.
