What if autism research has been asking too narrow a question?

Autism now affects an estimated 1 in 31 children in the United States, and families deserve honest answers about what may be driving that rise.
In this episode of the IMA Weekly Show, Dr. Joseph Varon sits down with Dr. Peter McCullough and Nicolas Hulscher for a discussion about a new review in the Journal of Independent Medicine examining the many factors that may contribute to autism spectrum disorder.
The paper, “Determinants of Autism Spectrum Disorder,” looks beyond any single proposed cause and reviews potential contributors through a broad, multifactorial framework, including genetics, parental age, prematurity, maternal immune activation, environmental toxicants, gut-brain disruption, in utero drug exposures, developmental regression, and the cumulative pediatric vaccine schedule.
The conversation covers:
• Why autism research must account for timing, cumulative exposure, and biologic vulnerability
• Why developmental regression is an important area for further study
• What limitations the authors see in existing autism and vaccine-related research
• Why the authors argue the full pediatric vaccine schedule has not been adequately studied
• What a more rigorous future study would need to include
• How physicians, parents, and policymakers can think more clearly about modifiable risk factors
Dr. Joseph Varon is President and Chief Medical Officer of the Independent Medical Alliance. Dr. Peter McCullough is President of the McCullough Foundation. Nicolas Hulscher is an epidemiologist and administrator at the McCullough Foundation.
This is a complex and emotional topic, but families deserve honest discussion, better data, and serious research.
Watch now to hear the full discussion.
