Aug 31, 2026 · 47m

Summary

Dr. Hyman and producer Emma explore the functional medicine perspective on ADHD, arguing it is a systemic issue rather than just a brain disorder. They discuss how gut health, microbiome dysbiosis, and inflammation directly impact cognitive function and behavior. The episode covers the gut-brain axis, the role of nutrient deficiencies, and how modern diets exacerbate symptoms. Dr. Hyman shares case studies showing that addressing root causes like gut overgrowth and food sensitivities can significantly improve or resolve ADHD symptoms.
