Research increasingly links social isolation to cognitive decline, depression, cardiovascular disease, and shortened lifespan. Yet despite these findings, we rarely explore how to build and sustain meaningful connection in a modern world designed for distraction. That’s why I invited Barnet Bain to join me on The Empowering Neurologist podcast. Barnet is a filmmaker, author, and educator whose work bridges psychology, spirituality, and lived human experience. You may recognize his work from films such as What Dreams May Come or Milton’s Secret, but his newest contribution may be his most relevant yet. His book, How to Be a Friend (In an Unfriendly World), is not about social performance or personality traits. It’s about safety, presence, listening, and emotional responsibility, qualities that directly influence nervous-system regulation and mental health. What makes this work especially important is that it reframes friendship as a skill set rather than a personality trait. Bain shows how fear, shame, unresolved trauma, and cultural conditioning quietly erode our relationships, and how conscious awareness can restore them. From a neurological perspective, this matters deeply. The brain is a social organ. Connection shapes stress responses, inflammation, cognition, and emotional regulation. Friendship isn’t a luxury, it’s foundational. This conversation isn’t about having more friends. It’s about being a better one. To others. And to yourself. In a world that feels increasingly fast, cold, and fragmented, this is a conversation worth having. ==== 00:00 Intro 02:58 Why Friendship Matters for Health and Resilience 06:24 From Columbia to the Practice of Presence 10:41 Friendship as Non-Transactional Love 14:20 The Childhood Stories That Shape the Self 21:39 Ad: Optoceutics 23:39 Projection, Parenting, and Conditional Love 30:08 Friendship as a Crucible for Self-Awareness 35:42 Why Connection Feels Harder in Modern Life 39:03 Safety, Self-Knowledge, and the Ground of Friendship 41:34 Ad: 3X4 Genetics 44:34 Boundaries, Values, and the Meaning of Honor 49:16 Friendship, Self-Forgiveness, and Inner Change 56:25 Presence as the Greatest Gift 58:34 Why Feeling Is Harder Than Doing ==== Barnet Bain is a Canadian filmmaker, author, and educator. His film credits include “Milton’s Secret” (director, writer), Oscar winner “What Dreams May Come” (producer), Emmy Award nominee for Outstanding TV Movie “Homeless to Harvard” (executive producer), “The Celestine Prophecy” (writer, producer), and “Jesus,” translated into more than 2,245 languages and often cited as the most widely seen film in history by The New York Times. ___________________________ Instagram: https://www.instagram.com/davidperlmutter/ Website: https://www.drperlmutter.com/ Subscribe to our channel: https://www.youtube.com/channel/UCDRl_UAXxbHyOOjklnA0dxQ/?sub_confirmation=1

You’ve Been Pooping All Wrong (And It’s Affecting Your Brain) with Dr. Trischa Pasricha | E213

Discover how to protect your brain and future health - reserve your copy today at https://www.braindefenders.com. ==== On this episode of The Empowering Neurologist, I spend time with Dr. Trisha Pasricha, gastroenterologist and author of the provocative and important new book, You’ve Been Pooping All Wrong. Yes, the title makes you smile, but the science inside should make all of us pay attention. Dr. Pasricha is part of a new generation of neurogastroenterologists exploring one of the most fascinating frontiers in medicine: the deep, bidirectional communication between the brain and the gut. Raised as the daughter of renowned gastroenterologist Dr. Pankaj “Jay” Pasricha and trained at Johns Hopkins, she brings both personal insight and rigorous science to a topic that too often lives in the shadows. What makes this book so important is that it dismantles myths we’ve carried since childhood. For example, at one point in the book she describes how students taking an oral exam nearly doubled their intestinal permeability, simply from psychological stress. That single experiment powerfully illustrates how the brain can alter gut biology in real time. And in another unforgettable section, she shares her early research showing that when subjects lied, their stomach’s electrical rhythm shifted into chaos, an arrhythmic pattern detectable on electrogastrogram. The stomach as a lie detector! That’s not just fascinating, it underscores how emotionally and neurologically integrated our digestive system truly is. ==== 00:00 Intro 03:05 Why We Need to Talk About Pooping 07:17 The Stigma Around Bowel Symptoms 09:31 Why Early-Onset Colorectal Cancer Is Rising 12:11 Should Screening Start Earlier? 14:59 Colonoscopy vs. Stool and Blood Tests 18:34 Ad: Optoceutics 20:35 Why Colonoscopy Still Matters Most 31:00 What “Leaky Gut” Really Means 34:42 What Worsens Intestinal Permeability 36:10 Ad: 3X4 Genetics 38:09 Gut Permeability, Inflammation, and Brain Disease 48:45 Could Fecal Transplants Help Parkinson’s? 56:52 The Different Causes of Constipation 1:02:23 The Myth of One Bowel Movement a Day 1:05:42 Final Takeaways on Gut and Brain Health ===== Trisha Pasricha, MD, MPH is an instructor of medicine at Harvard Medical School and the “Ask A Doctor” columnist for The Washington Post where she translates complex medical topics into must-read insights—with a touch of humor—for millions each week. A graduate of Harvard College, Dr. Pasricha earned her medical degree from Vanderbilt University School of Medicine and a Master of Public Health from the Harvard T.H. Chan School of Public Health. Her training includes an internal medicine residency at The Johns Hopkins Hospital and gastroenterology and motility fellowships at Massachusetts General Hospital. Currently, Dr. Pasricha serves as director of the Institute for Gut-Brain Research at Beth Israel Deaconess Medical Center, leading an NIH-funded research laboratory at the forefront of gut-brain science. Her work has been published in The New England Journal of Medicine, JAMA Network Open, and Nature Reviews. ___________________________ Instagram: https://www.instagram.com/davidperlmutter/ Website: https://www.drperlmutter.com/ Subscribe to our channel: https://www.youtube.com/channel/UCDRl_UAXxbHyOOjklnA0dxQ/?sub_confirmation=1

Discover how to protect your brain and future health - reserve your copy today at https://www.braindefenders.com. ==== If you’ve followed my work for any length of time, you know that one of the central themes we return to on The Empowering Neurologist is this: your brain is far more adaptable, resilient, and improvable than conventional wisdom ever allowed us to believe. This week, I’m thrilled to share a conversation with someone who has spent more than three decades proving exactly that. Dr. Majid Fotuhi, neurologist, neuroscientist, Harvard- and Johns Hopkins-trained physician, and now author of the new book The Invincible Brain, has dedicated his career to helping people reclaim their cognitive potential. His message aligns powerfully with the philosophy behind my upcoming book, Brain Defenders: that the trajectory of your brain is not predetermined, and that meaningful change is possible at any age. In our interview, we explore the groundbreaking ideas that shaped The Invincible Brain. Dr. Fotuhi lays out why intelligence is not fixed, how memory can be strengthened through surprisingly simple practices, and why Alzheimer’s disease is not the single, linear condition we once imagined, but rather a complex “soup” of abnormalities with multiple entry points for intervention. ==== 00:00 Intro 01:44 Choices influencing brain trajectory and resilience 04:25 Redefining intelligence beyond IQ 08:20 Synergy of memory and habit change 13:09 Challenging genetic determinism with epigenetics 18:00 Ad Break: Optoceutics 20:23 Alzheimer's as a metabolic and inflammatory soup 29:45 Ad Break: Fresh Pressed Olive Oil 38:04 Exercise and metabolism in brain health 43:45 Ad Break: 3x4 Genetics 49:38 Brain training and five pillars of brain health 54:55 Mindset as key to becoming a superager ==== Dr. Majid Fotuhi earned his PhD in Neuroscience from Johns Hopkins University in 1992 and his Medical Degree from Harvard Medical School in 1997. Currently, he serves as an adjunct professor at the Mind/Brain Institute at Johns Hopkins University, while also teaching at George Washington University and Harvard Medical School. With 37 years of experience in teaching, clinical practice, and neuroscience research, Dr. Fotuhi has pioneered a multidisciplinary approach to enhancing brain vitality and cognitive performance at any age. His groundbreaking “Brain Fitness Program” combines a comprehensive baseline “Brain Portfolio” assessment with 12 bi-weekly brain training sessions. This program targets lifestyle optimization and cognitive stimulation to improve memory, focus, and overall brain health. Dr. Fotuhi’s program has delivered measurable success for patients dealing with memory loss due to aging, concussions, and ADHD, as documented in several peer-reviewed journals. ___________________________ Instagram: https://www.instagram.com/davidperlmutter/ Website: https://www.drperlmutter.com/ Subscribe to our channel: https://www.youtube.com/channel/UCDRl_UAXxbHyOOjklnA0dxQ/?sub_confirmation=1
