307: What Causes Autism? - Inflammation, Immunity And Vaccines -with Dr. Theresa Lyons

Is autism purely genetic, or could environmental exposures, gut health, immune dysfunction and neuroinflammation play a much bigger role than we currently understand? In this fascinating conversation, Josh Dech sits down with Theresa Lyons, PhD, to explore the complex biological factors that may contribute to autism and why searching for one universal cause or treatment may be fundamentally misguided. With a PhD in computational chemistry from Yale and a background in pharmaceutical research and development, Theresa brings a scientific perspective to a deeply personal subject. After her daughter received an autism diagnosis, she began investigating the biological mechanisms, environmental risk factors and emerging research that could help parents better understand their children's health. Together, they explore the relationship between autism and the gut microbiome, including how antibiotics, environmental toxins, mold exposure, heavy metals and nutritional deficiencies may influence immune function and neurological development. They also examine maternal autoantibodies, cerebral folate deficiency and the potential relationship between dairy consumption and neurological inflammation. Theresa explains why some children may experience significant communication difficulties despite having far more cognitive ability than their outward behavior suggests. The conversation also tackles some of the most contentious questions surrounding autism, including vaccines, environmental exposures, genetic susceptibility and whether an autism diagnosis necessarily remains lifelong. Perhaps most importantly, this episode challenges parents to stop chasing someone else's success story. Autism is complex, and the factors influencing one child may be entirely different from those affecting another. Understanding the individual biology, investigating potential contributors and making informed decisions requires critical thinking rather than quick fixes. If you're interested in autism, gut health, the microbiome, inflammation, immune system function, environmental toxicity and root-cause approaches to chronic health challenges, this is an important conversation.
