The Principal Cause of Atopic Dermatitis
The Common Factor in All Patients—Including Those with ASD, ADHD, LD, or Sensory Traits

What if everything you've been told about atopic dermatitis (AD) is only part of the truth?

For decades, patients have been told that AD is caused by allergens, diet, stress, or environment. Yet countless people continue to suffer—despite eliminating triggers, trying every cream, and even relocating to new climates.

This groundbreaking book offers a radically different perspective.

Drawing on scientific research, case studies, and the author’s own journey as a patient, this book:
✅ Identifies the one factor that all AD patients appear to share
✅ Connects AD to neurodevelopmental traits such as sensory hypersensitivity, ADHD, ASD, and LD
✅ Explains why many treatments fail—and what we may need to focus on instead
✅ Offers a hopeful framework for understanding why recovery is possible

It’s also highly recommended for anyone who wants to understand—and come to peace with—the role of medication in treating AD. If you've ever felt conflicted about relying on steroids or immunosuppressants, this book may offer the clarity you’ve been searching for.

Whether you’re a patient, parent, or medical professional, this book will challenge assumptions and help you see atopic dermatitis in a completely new light.

★★★ Reader Comments ★★★

“The title is true. There is absolutely no room for objection. You may need to read this book with a certain amount of preparation, but if you do, you'll find it to be a book of true hope for us patients. I sincerely hope that professionals will recognize the importance of this book and not dismiss it.”

“The content is on a different level than other atopic dermatitis books in the bookstore. It may be a little difficult, but if you read it slowly, even a layperson can understand the contents. It has to be this serious to be credible. This might be a great book.”

“I devoured this book, thinking ‘so very true.’ It is a rich and authentic account based on your own experience, written over five years! I have been caring for patients with atopic dermatitis for 40 years and have recommended diet, exercises, and supplements without forcing them. I have also wondered about the recent trends in gut health and detoxification—‘How effective are they?’ I have learned a lot. Thank you very much.”
