The recent approval of leucovorin by the FDA as a treatment for autism symptoms has sparked significant debate. Many families, including those in New England, express hope after trying the drug, which was previously used for other medical conditions. However, scientists and autism advocates are skeptical about its efficacy, questioning the scientific basis of its promotion by public figures like Trump and RFK Jr. The drug, rebranded as an autism treatment, faces criticism for its unproven status, with calls for more data supporting its use. Concerns also arise regarding potential stigma tied to the federal claims surrounding the drug, further complicating discussions on autism treatment options.
