Right now, while Brain Defenders is still fresh, you have a limited window to join the Brain Defenders Immersion Course at a special rate reserved exclusively for book readers. When the timer runs out, the price returns to normal and this offer closes permanently.
What's Inside the Immersion Course?
The Immersion Course is structured around three core components, each designed to take readers from understanding the science to living it. Together, they form the most direct path from reading Brain Defenders to actually changing outcomes.
01
Chapter-by-chapter guiding videos
Dr. Perlmutter personally walks through Brain Defenders section by section, breaking down what to focus on, what the science actually means, and what matters most in each chapter. Readers never go through the material alone.
02
A complete FAQ video library
The real questions don't surface until someone starts applying this to their own life. What should someone do right now if Alzheimer's starts decades before symptoms? What does insulin resistance have to do with memory? The answers are already waiting.
03
A live group Q&A with Dr. Perlmutter
Not pre-recorded. A real conversation. Participants submit their questions, the team curates them, and Dr. Perlmutter answers them live for the group. He hosts very few of these each year.
From the desk of Dr. David Perlmutter
I'm genuinely delighted you're here.Â
I know what's at stake. I've lived it. I know what this information can do for a person, for a family, when it's engaged with and acted upon. I've spent my career trying to reach people before they're sitting across from a neurologist, hearing words they were never prepared for. I've talked with families who said, "I just wish we had known sooner." That's what drives me. That's what drove every page of this book.
But a roadmap only works if you get on the road. So I did something I've never done before. I went chapter by chapter through Brain Defenders and filmed dedicated guiding videos for every single section. This is me, personally, walking alongside readers through the material, showing them what to focus on, explaining the science in a way that clicks, and telling them what matters most, and why.
This book is the most important work of my career. And I want to be very clear: it is not the destination. It is the gateway. I built the Immersion Course to walk you through it, one chapter, one decision, one day at a time. The readers who go through this course don't just understand the science. They use it.
