What if Alzheimer’s disease isn’t inevitable? In this powerful episode of The Science of Sound, Dr. Paul Harris breaks down what you don’t know about Alzheimer’s, why millions are at risk earlier than they realize, and the science showing that Alzheimer’s may one day be an optional disease. Nearly 7 million Americans are affected today—and that number will double by 2060—yet most people still believe outdated theories about beta-amyloid plaque being the main cause. Dr. Harris reveals what modern research actually shows: insulin resistance, chronic inflammation, toxins, mold exposure, vascular dysfunction, mitochondrial decline, leaky gut, poor sleep, and genetic factors all play major roles.

You’ll learn why Alzheimer’s can begin in your 20s, how glucose hypometabolism starves the brain, the link between insulin and plaque buildup, why gut health predicts cognitive health, and what labs can identify risk decades early. Dr. Harris also explains how fasting, ketogenic strategies, ketone supplements, exercise, and mitochondrial repair can support brain function—plus the surprising tests that reveal inflammation, toxins, heavy metals, and APOE status. If you’re searching for Alzheimer’s prevention, reversal protocols, brain optimization, dementia warning signs, ketogenic brain health, or what REALLY causes Alzheimer’s, this episode is an essential guide.
