A substantial study published in PLOS Medicine has explored the link between prenatal exposure to maternal depression and antidepressants and neurodevelopmental outcomes in children. The research, which connected health and school records for over 167,000 children, found a slightly higher rate of special educational needs in children whose mothers had depression and were prescribed antidepressants during pregnancy.
Professor Asma Khalil from City St George’s, University of London, noted that special educational needs were estimated in approximately 24 out of 100 children whose mothers had recorded depression without an antidepressant prescription, compared to about 27 out of 100 whose mothers had both. While this difference is worth studying, experts caution it does not prove antidepressants caused it.
Professor Chiara Nosarti of King’s College London highlighted that women receiving antidepressant treatment may have more severe or persistent depression, making it challenging to separate the effects of the underlying depression from the treatment. Maternal depression itself can be associated with children's developmental and educational outcomes, even in cases of mild symptoms.
Professor Stella Chan from the University of Reading emphasised the complexity of the associations, noting that factors such as the severity and family history of depression, as well as heritable neurodevelopmental disorders, were not fully examined. Professor David Curtis of UCL Genetics Institute also pointed out that confounding variables like deprivation, maternal age, and smoking status were strongly associated with the outcomes.
