Overview

• President Trump is slated to deliver the autism announcement today from the Oval Office alongside HHS Secretary Robert F. Kennedy Jr. and CMS Administrator Mehmet Oz.
• Reports indicate officials will advise pregnant patients to limit acetaminophen use to treating high fevers and will flag low maternal folate as a risk factor.
• Leucovorin, a form of folate, is expected to be highlighted as a possible therapy to reduce symptoms in some people with autism.
• Tylenol maker Kenvue and major medical organizations dispute a causal link and maintain that acetaminophen remains an appropriate option in pregnancy when used as directed.
• Researchers describe mixed evidence, with observational reviews noting associations, while a large 2024 sibling‑controlled JAMA study from Sweden found no increased autism risk.
