This course walks the reader through every chapter of Brain Defenders by David Perlmutter, MD — from the immunometabolic framing in Part I, through the friends and foes of brain health in Parts II and III, to the breakthrough therapies on the horizon in Part IV. Each chapter is taught four ways: read, listened, watched, and tested. Lumina, your AI study companion, is one click away.
Each chapter is a single body of material taught four ways. The repetition is the point — different formats reinforce different memory traces. We recommend you work through them in this order:
Open the Lesson tab and play the audio while you read. Reading and listening together engage two channels and lock in the material faster than either alone.
The Podcast tab is a conversational walkthrough of the same material — same concepts, different angle. Listen on a walk, in the car, or while you cook.
The Animation tab is a visual recap. Diagrams, timelines, and motion fix the spatial relationships that paragraphs can't.
Aim for the 75% pass threshold. If you don't pass, return to step 1 — the gaps the quiz reveals are exactly what the next pass should target. If you pass, move on.
There's no time limit and no penalty for retaking quizzes — your best score counts. Each chapter is sized for about an hour of focused work.
The book moves through four movements: the framework, the foes, the defenses, and the horizon. You can study out of order if you have a focus area, but each later chapter assumes the earlier framing.
