36. Why Dementia Prevention Beats Treatment: APOE Testing, Women's Brain Health, and the Levers You Control

If you live into your mid-eighties, your odds of dementia are roughly one in three. Most people spend zero minutes of midlife thinking about it — and Dr. Vikas Patel and Dr. Nisha Patel make the case that's backwards, because nearly half of dementia risk traces to things you can actually change.We get into APOE — the gene everyone's testing for and half the time misreading, and what one copy versus two really means. The badly under-told story of women's brain health: two-thirds of Alzheimer's is in women, the APOE4 gene hits them far harder than men, and menopause looks less like a reproductive event than a brain inflection point. The randomized-trial evidence that lifestyle protects cognition, even in gene carriers. And an honest look at the new Alzheimer's drugs, and why "slows decline by 27%" means far less than the headline suggests.The brain you have at eighty-five is being built — or eroded — by the choices you're making at fifty.

It's the most empowering sentence in medicine.🎧 Listen on Apple Podcasts, Spotify, and YouTube📝 Subscribe: mdlongevitylab.substack.com📞 Book a 3-hour appointment: 224-208-3720📖 Book coming soon — by Dr. Vikas Patel.
