About Re-Think Aging with Cynthia Libert, M.D.

Welcome to Re-Think Aging with Dr. Libert, where we challenge the status quo of aging and empower you to take control of your brain health, energy, and longevity. I’m Cynthia Libert M.D., a board-certified physician specializing in cognitive decline prevention and whole-person wellness. My mission is to help high-achieving, health-conscious individuals—especially those over 40—prevent chronic disease, optimize brain vitality, and live with energy, clarity, and purpose. Aging is often viewed as an inevitable decline, but it doesn’t have to be that way. Science now shows that cognitive decline and many age-related conditions are preventable—and even reversible—with the right strategies. The Re-Think Aging channel exists to bridge the gap between cutting-edge medical research and practical, real-world application. Let’s rewrite the narrative on aging together. Because your best years are ahead! Welcome to the Re-Think Aging community. Hosted on Acast. See acast.com/privacy (https://acast.com/privacy) for more information.

   E32: You Found Out You Have the Alzheimer's Gene. Here's What to Do Next.

   Free Strategy Session with Dr. Cindy (https://www.caringforthebody.org/free-strategy-session) In this episode, Dr. Cindy welcomes back Carol McCarthy, certified brain health coach and functional genomics specialist at Caring for the Body, PLLC Center for Functional Medicine (https://www.caringforthebody.org/), to tackle one of the most emotionally charged conversations in brain health: what it means to carry the APOE4 allele, commonly called the Alzheimer's gene. With compassion and clinical clarity, they walk through what this gene actually does in the body, why having it is not a diagnosis, and why so many people who carry it never develop Alzheimer's disease at all. Dr. Cindy and Carol explain that APOE is not, first and foremost, an Alzheimer's gene. Its primary job is transporting cholesterol and fats throughout the brain, supporting neuronal repair, clearing debris, and maintaining the brain's internal environment. The APOE4 variant simply does this job a little less efficiently, and when combined with a modern lifestyle full of chronic stress, poor sleep, ultra-processed foods, and environmental toxins, that reduced efficiency can accumulate over decades into meaningful risk. Carol shares her memorable garbage truck analogy to bring this science to life, and both she and Dr. Cindy emphasize that the very lifestyle factors driving that risk are largely within our control. The episode closes with a rapid-fire Q&A covering the questions APOE4 carriers ask most: coffee, alcohol, creatine, fish oil, saturated fat, fasting, sauna, hormone therapy for women, strength training versus cardio, sleep apnea, and whether there is a supplement stack worth following. Dr. Cindy answers each one with her characteristic mix of nuance and practicality, always returning to the same core message: the goal is not a perfect protocol, it is a personalized, sustainable approach to building the healthiest brain possible. You'll learn: What the APOE Gene Actually Does in the Brain and Why APOE4 Affects Alzheimer's Risk Why Carrying APOE4 Is Not a Diagnosis and Does Not Determine Your Destiny The Evolutionary Reason APOE4 Survived and Why It Clashes with the Modern World What the Science Says About Coffee, Alcohol, Creatine, Fasting, and Hormone Therapy for APOE4 Carriers The First Steps to Take If You Just Found Out You Carry the APOE4 Allele You are invited to join the Re-Think Aging Community (https://www.caringforthebody.org/) to access resources for your journey Resources Mentioned In This Episode: Dr. Stacy Sims (https://www.drstacysims.com/) Dr. Dale Bredesen and the Pacific Neuroscience Institute (https://www.pacificneuroscienceinstitute.org/people/dale-bredesen/) The Re-Think Aging Community (https://www.caringforthebody.org/services/the-rethink-aging-community) Free Strategy Session with Dr. Cindy (https://www.caringforthebody.org/free-strategy-session) CaringForTheBody.org (http://caringforthebody.org) Subscribe now for new episodes on the first and third Mondays of each month, and receive inspiration to help you live with more clarity, peace, and purpose, from the inside out.

   E31: Is There a Blood Test for Alzheimer's? What New Biomarkers Reveal Before Symptoms Appear

   Free Strategy Session with Dr. Cindy (https://www.caringforthebody.org/free-strategy-session) In this episode, Dr. Cindy is joined by co-host Carol McCarthy, functional genomics specialist and brain health coach at Caring for the Body, PLLC Center for Functional Medicine (https://www.caringforthebody.org/), for a conversation that is changing what is possible in Alzheimer's prevention. Together they unpack three emerging blood biomarkers, p-tau217, neurofilament light (NfL), and GFAP, that can reveal biological changes in the brain before significant cognitive symptoms ever appear. For the first time, a conversation that once had to wait until memory loss was obvious can now begin years, even decades, earlier. Dr. Cindy walks through what each biomarker measures and what it can and cannot tell us. P-tau217 looks for Alzheimer's-related pathology developing in the brain. NfL signals active neuronal injury, though from any cause. GFAP reflects whether the brain's support cells are responding to stress or damage. No single marker tells the whole story, and none of them delivers a diagnosis, but together and placed in the context of a patient's full history, genetics, lifestyle, and cognitive testing, they open a powerful window for proactive action. Carol brings the coaching perspective, addressing the fear, hypervigilance, and overwhelm that can follow an abnormal result. She shares how she helps patients shift from "Am I going to get Alzheimer's?" to "What can I do to build the healthiest brain possible?" and how sustainable change comes not from overhauling everything at once, but from finding the next best step, building a small win, and letting momentum carry the journey forward. You'll learn: ➡️ What p-tau217, NfL, and GFAP Each Measure and What They Cannot Tell You ➡️ Why These Biomarkers Open a Window for Prevention Before Symptoms Appear ➡️ How to Hold Abnormal Results Without Fear, Catastrophizing, or Hypervigilance ➡️ How Genetic Factors Like APOE4 Interact with Lifestyle to Shape Alzheimer's Risk ➡️ Why Sustainable Brain Health Is Built on Small Consistent Steps, Not Overnight Overhauls You are invited to join the Re-Think Aging Community (https://www.caringforthebody.org/) to access resources for your journey Resources Mentioned In This Episode: NeuroCode (https://www.neurocode.com/) The Re-Think Aging Community (https://www.caringforthebody.org/services/the-rethink-aging-community) Free Strategy Session with Dr. Cindy (https://www.caringforthebody.org/free-strategy-session) CaringForTheBody.org (http://caringforthebody.org) Subscribe now for new episodes on the first and third Mondays of each month, and receive inspiration to help you live with more clarity, peace, and purpose, from the inside out.

   E30: Why Is My Brain So Foggy? 5 Root Causes and How to Clear Them

   Free Strategy Session with Dr. Cindy (https://www.caringforthebody.org/free-strategy-session) Brain fog is one of the most common complaints Dr. Cindy hears in her clinical practice, and one of the most misunderstood. In this focused, practical episode of Re-Think Aging (https://www.caringforthebody.org/rethink-aging), she draws on more than two decades of functional medicine experience to walk through the five most common root causes of brain fog, and why so many of them are reversible with the right approach. Dr. Cindy reframes brain fog not as an inevitable part of aging, but as a meaningful signal worth investigating. She walks through each of the five root causes with clinical clarity, explaining how poor sleep, blood sugar swings, hormonal shifts, missing nutrients, and hidden inflammation can quietly rob the brain of its sharpness. Drawing on her own experience with brain fog during a season of chronic stress and sleep deprivation, she brings both the perspective of a physician and the honesty of someone who has lived it. Rather than offering quick fixes, Dr. Cindy presents a root-cause roadmap that empowers listeners to ask better questions, work with their healthcare providers, and take meaningful action. The message throughout is one of hope: brain fog is often a signal, not a sentence, and understanding what your body is communicating is the first step toward getting your clarity back. You'll learn: Why Sleep Quality Matters More Than Sleep Quantity for Brain Function How Blood Sugar Instability and Insulin Resistance Cloud Mental Clarity The Role of Thyroid and Sex Hormone Decline in Midlife Brain Fog Which Key Nutrients the Brain Needs to Function at Its Best How Chronic Inflammation and Medications Can Quietly Impair Cognition Viewers are invited to join the Re-Think Aging Community (https://www.caringforthebody.org/) to access resources for their journey Resources Mentioned In This Episode: Free Strategy Session with Dr. Cindy (https://www.caringforthebody.org/free-strategy-session) The Re-Think Aging Community (https://www.caringforthebody.org/services/the-rethink-aging-community) CaringForTheBody.org (http://caringforthebody.org) Subscribe now for new episodes on the first and third Mondays of each month, and receive inspiration to help you live with more clarity, peace, and purpose, from the inside out.
