How to Catch Alzheimer’s Before It Starts, with Dr. Eric Topol
On this episode of The Doctor Hyman Show, I sit down with Dr. Eric Topol—renowned cardiologist, geneticist, and founder of the Scripps Research Translational Institute—to talk about the future of disease prevention. From AI diagnostics to genetic risk scoring, we explore the tools that could help stop Alzheimer’s and other chronic diseases before they start.
This is one of the most hopeful conversations I’ve had about what’s ahead. Watch it on YouTube here.
We discuss:
• How new diagnostics and AI tools could help detect Alzheimer’s early
• The key lab tests and biomarkers to know—and how to talk to your doctor about them
• Why tracking your health data over time matters more than you think
• What you can do to strengthen your immune system and lower disease risk
We have more power than ever to take control of our health. This episode shows you where to start.

Psychedelics, Depression, and the Brain: A Breakthrough Framework for Mental Health
What if the key to healing depression isn’t another pill but a profound shift in consciousness?
On this episode of The Dr. Hyman Show, I talk with Dr. Robin Carhart-Harris, one of the world’s leading psychedelic researchers, about how these compounds unlock plasticity in the brain and offer new hope for people with treatment-resistant mental health challenges.
From trauma recovery to the entropic brain principle, this is a conversation that challenges everything we think we know about the mind. You can watch the full episode on YouTube - https://youtu.be/P0EDsfPwbUQ
In this episode, you’ll learn:
• What happens in the brain during a psychedelic experience and why it matters
• How the right set, setting, and support can shape the outcome of your healing journey
• Why some people improve after one session, while others need a longer path
• The risks of self-medicating and how to explore psychedelics safely
• How emerging tools, including AI, could help personalize treatment and improve recovery
If you’re curious about the healing potential of psychedelics, this is an honest, research-backed conversation worth tuning into.

What If We Got Sunlight All Wrong? The Truth About Vitamin D & Chronic Disease
Sunlight has long been vilified for its link to skin cancer, yet hiding from it entirely may be costing us far more. Vitamin D, made primarily through sun exposure, plays a pivotal role in everything from bone strength and immune defense to mood regulation, cancer prevention, and even longevity. Shockingly, over 80% of people have levels too low to unlock its protective powers—putting them at greater risk for chronic illness, and even premature death. Research shows that raising vitamin D to optimal levels could prevent hundreds of thousands of deaths each year, rivaling or surpassing the impact of many medical interventions. With a few minutes of daily sun, the right kind of supplementation, and awareness of how our lifestyles block this essential nutrient, reclaiming our health may be simpler than we think.
In this episode, I discuss, along with Dr. Cindy Geyer, the critical role of vitamin D in preventing chronic disease, boosting immunity, and promoting overall health.
Dr. Cindy Geyer received her bachelor of science and her doctor of medicine degrees, with honors, from the Ohio State University. She completed residency in internal medicine at Strong Memorial Hospital in Rochester, N.Y. and is triple board certified in internal medicine, integrative medicine and lifestyle medicine.

Bonus Episode: Treating High Blood Pressure at the UltraWellness Center
This special bonus episode features Dr. Cindy Geyer from the UltraWellness Center, diving into how functional medicine approaches high blood pressure — and why treating the root cause means looking far beyond salt and stress.
In this conversation, Dr. Geyer walks through the case of a woman with longstanding “white coat” hypertension, family history of cognitive decline, and no clear answers from conventional care. By investigating deeper factors like sleep quality, metabolic health, stress hormones, genetics, and gut function, Dr. Geyer shows how a systems-based approach can improve blood pressure, energy, and long-term brain health — often without medication.
You’ll learn:
• Why blood pressure medications don’t address the real problem
• How stress, sleep apnea, and insulin resistance all contribute to hypertension
• Why women are often misdiagnosed or overlooked when it comes to vascular risk
• How gut health and food sensitivities can directly affect blood pressure
• What functional medicine labs reveal that standard workups miss
This is part of a limited bonus series spotlighting the work of the UltraWellness Center team, with new episodes dropping monthly on select Fridays.

Why Chronic Disease is Exploding w/ Daniel Schmachtenberger
I recently sat down with Daniel Schmachtenberger, a strategist and founding voice behind The Consilience Project, to explore the deeper systems fueling today’s chronic disease epidemic.
On this episode of The Dr. Hyman Show, Daniel shares a powerful perspective on how modern life impacts our health and what it will take to create lasting change.
Here’s what we cover:
• Why chronic disease today is largely “man-made” and what that actually means
• How pollution, industrial systems, and healthcare itself are quietly driving illness
• Why medical stats can be misleading and how to think beyond symptom management
• What it will take to build a system that prioritizes prevention and real well-being
This episode offers a rare lens on the systems shaping our well-being. I hope it sparks new insights and inspires action.
