School-age social behavior and pragmatic language ability in children with prenatal serotonin reuptake inhibitor exposure

Area of Science:

• Developmental Psychology
• Neuroscience
• Pediatric Psychiatry

Background:

• Existing research on prenatal serotonin reuptuptake inhibitor (SRI) exposure and child autism spectrum disorder (ASD) or language delays is inconsistent.
• Previous studies often lack prospective follow-up or rigorous diagnostic tools, limiting definitive conclusions.

Purpose of the Study:

• To prospectively investigate the association between prenatal SRI exposure and ASD-related behaviors and pragmatic language development in children.
• To utilize gold-standard assessments for a more accurate evaluation of potential links.

Main Methods:

• A prospective cohort study followed 178 mother-child dyads from pregnancy through early elementary school.
• Maternal and alternate-caregiver behavioral ratings for ASD were collected (N=137).
• Direct, gold-standard assessments of ASD symptoms and pragmatic language were conducted on a subset (N=44) with prenatal depression and SRI exposure or no medication.

Main Results:

• Prenatal SRI exposure correlated with maternal-reported ASD-related behaviors and, in boys, alternate-caregiver-reported behaviors.
• Direct assessments indicated an association between SRI exposure and reduced pragmatic language scores.
• No significant association was found between prenatal SRI exposure and ASD diagnoses via direct assessment tools (ADOS, SRS).

Conclusions:

• The findings suggest prenatal SRI exposure may be associated with pragmatic language difficulties and certain behavioral ratings, but not directly with ASD diagnoses.
• Discrepancies highlight potential assessment challenges and the possibility that SRIs are more linked to language or broader behaviors overlapping with ASD.
• Further large-scale prospective studies with comprehensive, gold-standard assessments are crucial to clarify these relationships.
