Trump to Announce Autism Finding; HHS Studies Prenatal Tylenol

The administration says a significant medical announcement on childhood autism is imminent, with President Trump indicating researchers may have 'found an answer.'

Officials describe a broad research initiative launched earlier this year to probe autism etiology and plan to present new findings publicly. White House spokespeople framed the move as addressing root causes, increasing transparency and applying rigorous science to a growing public health concern.

Separately, Health and Human Services officials are evaluating whether prenatal acetaminophen exposure could be associated with autism risk and are expected to advise against routine Tylenol use during pregnancy except for treating fever. Manufacturer statements counter that acetaminophen remains the safest analgesic option for expectant mothers, noting alternatives carry their own risks.

Public health agencies note autism prevalence estimates have risen over decades, a trend partly attributed to changes in diagnostic practices and service availability rather than a single causal factor. Some officials emphasize environmental contributors as potential drivers and say the forthcoming announcement will clarify next steps for research and clinical guidance.
