Drugs affecting neurotransmitter systems not associated with risk of autism

A case‐control study involving children born between 1997 and 2007 has concluded that prenatal exposure to most of the medications that affect neurotransmitter systems is not associated with risk of autism spectrum disorder (ASD) in children. The study employed a novel strategy that grouped medications into classes based on their target neurotransmitter, thus grouping together some drugs regardless of the various medical indications for which they were being used. Study results were published online Oct. 31 in JAMA Psychiatry.
