Your brain is not losing its mind by accident. It has been compounding every decision you've made for the last thirty years.

Louisa Nicola is one of my closest friends, and one of the most brilliant neurophysiologists working today, an elite triathlete and PhD researcher who has dedicated her life to understanding how the brain ages and, more importantly, how to stop it from declining. In this episode, Louisa and I pull back the curtain on everything you thought you knew about Alzheimer's disease, starting with the truth about amyloid, the protein we've been blaming for decades that is actually your brain's own defense system, and we build you a real, science-backed brain insurance policy: the specific exercise protocols, sleep requirements, hormonal factors, and daily habits that determine whether your mind stays sharp and fully yours well into your eighties and beyond.

What we cover:

- How amyloid, long blamed as the villain of Alzheimer's disease, is actually your brain's own antimicrobial defense system.

- Why Alzheimer's begins silently in your thirties and forties, not your eighties, compounding over decades.

- What cognitive reserve means at the cellular level and how to build more of it starting now.

- The specific exercise protocols, including resistance training and zone five, that protect your brain most.

- How deep sleep triggers your brain's nightly cleaning system and why skipping it accelerates decline.

- Why doing hard things, and learning new skills across your lifespan, physically grows your brain. About Louisa Nicola:

Louisa Nicola is a neurophysiologist, Alzheimer's Disease scientist, and global authority on brain health. She is the founder of Neuro Athletics and the creator of BRAIN CODE, a science-driven program designed to help midlife women reduce their risk of Alzheimer's disease through measurable, preventative strategies.

Trained at the University of Sydney Medical School, Louisa relocated to New York to work alongside leading neurosurgeons, contributing to clinical research in cranioplasty and post-operative neurological outcomes. Her work sits at the intersection of neurophysiology and exercise science, decoding how targeted lifestyle interventions rewire neural resilience and reshape the trajectory of cognitive aging.

Through her research, keynote speaking, and top-ranked neuroscience podcast, Louisa challenges the fatalistic narrative around cognitive decline. Her mission is clear: Alzheimer's is a preventable disease, and women deserve the knowledge, tools, and measurable strategies to reduce their risk long before decline begins.
