Host Holly Wayment interviews this highly experienced pediatric psychiatrist .  Dr. Boddapadi  explains that autism has no single cause — it’s multifactorial, involving strong genetic risks and environmental factors.  Vaccines have been ruled out as a cause, and  evidence  shows a very weak association with Tylenol. The conversation emphasizes taking care of maternal health, discussing medications with clinicians, following evidence-based guidance, and the importance of early identification and support for children with autism.
