The Strong Center for Developmental Disabilities values the lives of autistic people. In doing so, we reiterate and support the statement from Society for Developmental and Behavioral Pediatrics. We stand with families, scientists, and clinicians to emphasize that messaging about the causes of autism must be rooted in unbiased scientific findings.
Decades of research shows that autism has complex causes involving both genetics and environmental influences working together. Autism is not caused by anything that parents did or did not do. There is no strong evidence showing a direct relationship between appropriate use of acetaminophen (Tylenol) during pregnancy and harmful effects on fetal development.
Autistic people and people with other disabilities should be valued, not vilified. Unscientific, overly simplistic, and premature assertions about causes and treatments are a distraction from the real needs of the autism community.
