Your brain is your most powerful asset—so why do so many of us let it decline without a fight? Cognitive decline, brain fog, and even Alzheimer's don't just "happen." They're the result of decades of small decisions, stress, and overlooked habits. The good news? You have the ability to take control.

In this episode of Extend, I sit down with Louisa Nicola, neurophysiologist and human performance coach, to uncover the science behind optimal brain health and the simple habits that can keep your mind sharp and resilient.

We talk about the role of exercise (and why your muscles are key to brain health), how sleep works like a "cleaning system" for your brain, and why inflammation is the root of so many cognitive issues.

Louisa Nicola is a neurophysiologist and founder of NeuroAthletics, specializing in brain optimization and cognitive performance. With a background as an elite triathlete, she focuses on using exercise and science-backed protocols to prevent neurodegenerative diseases. Louisa works with top executives, athletes, and high achievers worldwide.
