There is no clear link between antidepressant use during pregnancy and autism or ADHD in children, according to a comprehensive evidence review analyzing nearly 650,000 pregnancies in which antidepressants were used, compared to nearly 25 million pregnancies not exposed to antidepressants. The study examined 37 previous research papers to provide the most thorough assessment to date.
Initial analysis appeared to show a connection: antidepressant use during pregnancy was associated with a 35% higher risk of ADHD, and a higher risk of autism without intellectual disabilities. However, when researchers accounted for other factors influencing neurodevelopment, the risks significantly diminished. “Although our study found a small increase in the risk of autism and ADHD in the children of women who had used antidepressants during pregnancy, it also found that this risk disappeared when we accounted for other factors,” said lead researcher Dr. Wing Chung Chang of the University of Hong Kong.
Genetic Factors, Not Medication
The key finding was that increased risk was also observed in children of fathers who took antidepressants and of mothers with antidepressant use before, but not during, pregnancy. “Together, this suggests that it is not the antidepressants themselves causing an increased risk in autism and ADHD but it is more likely to be due to other factors, including genetic predisposition to conditions such as ADHD, autism and mental health conditions,” Chang noted.
When examining specific antidepressant types, the analysis found no link at all for first-line selective serotonin reuptake inhibitors (SSRIs). The evidence further suggests that genetic factors and the mental health status of parents themselves influence offspring neurodevelopment more than the medications used.
Treatment Considerations
While all medications carry risks, so too does stopping antidepressants during pregnancy, which increases the risk of relapse. For women with moderate to severe depression, doctors and patients must carefully weigh the potential risks and benefits of continuing antidepressant treatment during pregnancy against the potential harms of untreated depression.
