In this episode, I sit down with leading neuroscientist Louisa Nicola to break down what women actually need to understand about Alzheimer’s risk, cognitive decline, and how to protect long-term brain health starting now — not decades from now.
Louisa Nicola is a neuroscientist, human performance strategist, and educator specializing in brain optimization, cognitive longevity, and neurodegenerative disease prevention. She’s known for translating complex neuroscience into practical, evidence-based strategies that help people protect memory, improve focus, and build resilient brains across the lifespan. Her work bridges clinical research, performance science, and everyday health habits so listeners can apply neuroscience in real life.
This conversation goes far beyond surface-level wellness advice. We dive into genetics, advanced lab testing, metabolic health, exercise science, and sleep physiology to uncover what truly moves the needle when it comes to protecting your brain for life.
We unpack:
- What the APOE4 gene actually means for Alzheimer’s risk — and what it doesn’t
- New blood biomarkers that can detect amyloid and tau decades before symptoms
- Why muscle acts as a metabolic sink for glucose and how that protects the brain
- The science behind resistance training and high-intensity exercise for brain growth factors
- How sleep activates the glymphatic system to clear toxic proteins from the brain
- The connection between perimenopause, hormones, and cognitive changes
- Whether hormone therapy may influence dementia risk
Whether you’re in your 30s thinking preventatively or later in life optimizing your current health, this conversation gives you tools to think about brain longevity in a clear, strategic way.
