4 published verifications about Autism Spectrum Disorder (ASD) Autism Spectrum Disorder (ASD) ×
“The diagnostic literature on autism describes autistic people who are frequently devastated by accidentally breaking social rules they were trying hard to follow.”
The core diagnostic literature does not describe autism in the specific terms used here. DSM-5 and ICD-11 discuss social-communication differences, rigidity, rituals, and distress around change, but they do not say autistic people are frequently devastated after accidentally breaking social rules they were trying to follow. That reaction may be compatible with some autistic experiences, but the claim overstates what the diagnostic texts actually say.
“The United States Food and Drug Administration has approved leucovorin as a broad treatment for autism.”
This claim is false. The FDA approved leucovorin in March 2026 only for cerebral folate deficiency (CFD), an ultra-rare genetic condition affecting roughly 1 in a million people — not for autism. Leucovorin remains investigational for autism, the American Academy of Pediatrics does not recommend its routine use for autistic children, and a key study supporting leucovorin's autism benefits was retracted in January 2026 due to data irregularities. No FDA-approved broad treatment for autism spectrum disorder exists.
“The MMR (measles, mumps, and rubella) vaccine causes autism in children.”
This claim is false. The sole study linking MMR to autism (Wakefield, 1998) was retracted by The Lancet for deliberate fraud. Since then, overwhelming scientific evidence — including WHO's 2025 review of 31 studies, a Cochrane review of 23 million children, and a meta-analysis of 1.25 million children — consistently finds no causal link between the MMR vaccine and autism. Every major health authority (WHO, AAP, National Academies) confirms vaccines do not cause autism.
“Vaccines cause autism spectrum disorder in children.”
This claim is false. Decades of research — including WHO's December 2025 review of 31 studies, a Danish study of over 1 million children, and reviews by the National Academies and AAP — consistently find no causal link between vaccines and autism. The original 1998 Wakefield study that sparked this myth was retracted for fraud. A 2025 CDC website update noting causation hasn't been "ruled out" reflects uncertainty, not evidence of causation, and was criticized by the National Academies for lacking context.
