Alzheimer’s Is 95% Preventable — Here’s the Science

For decades, we’ve been told Alzheimer’s strikes in our 70s or 80s — but that’s not the full story. The truth is, it begins silently, building for years—sometimes decades—before symptoms ever appear. And by the time you notice it, the damage has already been done. In this solo episode, I break down what I’ve learned after a decade studying brain health — especially the unique risks women face in midlife. Two out of three cases of Alzheimer’s are female. Why? It’s not just about age — it’s about hormones, metabolism, and lifestyle choices that start changing in our 30s, 40s, and 50s. I’ll also share why I created Brain Code™ — my new digital course for women 40+ who want a science-backed plan to lower their risk of cognitive decline and live sharper, longer, and stronger lives. This isn’t optional self-care — it’s your cognitive Olympics. *** Subscribe to The Neuro Experience for more conversations at the intersection of brain science and performance.
