Autism Diagnoses Surge in U.S., Experts Highlight Concerns

There has been a significant increase in autism diagnoses in recent years, attributed by experts to expanded diagnostic criteria, greater awareness, and improved screening tools, rather than a sudden rise in actual cases. Some officials, such as U.S. Health Secretary Robert F. Kennedy Jr., have linked this increase to environmental toxins or vaccines, but these claims are widely rejected by the scientific community and advocacy organizations, who emphasize that autism is a complex, largely genetic condition. Critics warn that labeling the rise as an 'epidemic' and pursuing controversial theories can be harmful, misleading, and stigmatizing for autistic individuals. Additionally, some commentators and researchers caution that overdiagnosis, especially at the milder end of the spectrum, may have unintended negative consequences and question the overall societal benefit of such broad labeling. Despite ongoing debates, many agree that improved recognition of autism, particularly in teens and adults who were previously overlooked, is helping individuals access support and fostering greater understanding and inclusion. Advocacy groups continue to promote acceptance and warn against fear-driven narratives that misrepresent the nature of autism.
