78.3% Alzheimer's Patients Are Women: Here’s How to Fix It. (Yes really)
About this episode
This episode discusses the neurological implications of menopause on Alzheimer's disease, particularly in women, and offers evidence-based protections.
Two out of three Alzheimer's patients are women, and for decades that gap was written off as a side effect of living longer. The newer neuroscience tells a more specific story: menopause is not a reproductive event, it's a neurological one, and the pathology begins 20 to 30 years before the first symptom. In this episode, Louisa breaks down why the female brain loses its primary protection around 40, what actually drives the disease, and the seven evidence-based protections that can change the trajectory. She starts with the estrogen shield, the four things estrogen does in the female brain that nothing else replicates: it drives mitochondrial biogenesis, suppresses amyloid plaque formation, upregulates antioxidant enzymes, and maintains white matter integrity. You'll hear why estrogen doesn't decline smoothly but swings wildly through perimenopause before dropping roughly 80% by postmenopause, what PET scans already show in women in midlife, and why a 2021 paper by Mosconi and colleagues named menopause the single strongest predictor of Alzheimer's brain changes, stronger than age, stronger than family history. Then she turns to what you can do about it. You'll learn why…
