The question of whether epidurals cause autism gained attention after a 2020 study in JAMA Pediatrics found a statistical association. However, subsequent research and expert analysis have largely refuted a causal connection.

What the Initial Study Found

A 2020 study of over 147,000 births reported a modest association between epidural use and later autism diagnosis. However, the study had significant limitations and the authors themselves cautioned against interpreting results as causal.

Why the Association Is Likely Not Causal

• Multiple follow-up studies found no association after better controlling for confounding factors
• A large Swedish study of over 1.2 million births found no link
• Epidurals affect the mother, not the fetus s brain development
• Autism has prenatal origins that precede labor and delivery

What Experts Say

The American College of Obstetricians and Gynecologists, the Society for Maternal-Fetal Medicine, and the American Society of Anesthesiologists have all stated that epidurals remain safe and should not be avoided due to autism concerns.
