This book is dedicated to all the courageous children and to all who love and serve them. We are humbled in your presence.

With gratitude, we also dedicate this edition to our distinguished colleagues in functional medicine and nutrition whose contributions have helped advance treatments and improve recovery rates for children with ADHD and autism.

With special appreciation, we also recognize the Autism Research Institute for its unwavering commitment to supporting research, educating professionals, families and patients, and providing opportunities for practitioners from diverse fields to convene and share their knowledge and expertise.

Our hope is to continue to educate ourselves, our patients, and their families as we share their journeys. Our goal is to help those with ADHD and autism achieve their best individual potential.

And finally, we honor the three pioneers whose foresight and brilliance changed the trajectory of evaluation, research, and treatment, achieving a far-reaching paradigm shift: Bernard Rimland, Sidney MacDonald Baker, and Jon Pangborn.
