This episode is brought to you by Athletic Greens and ButcherBox.   For so long, we’ve been told that memory loss and dementia are just normal parts of aging. We now know it doesn’t have to be that way, and that there are many measures we can proactively take to avoid cognitive decline as we age. Emerging research is helping us look at new ways to treat and even prevent devastating neurological diseases like Alzheimer’s and dementia, giving people a newfound sense of hope.   In today’s episode, I talk with Dr. Marwan Sabbagh, Dr. Richard Isaacson, and Dr. Jay Lombard about the role of genetics in brain disorders, lifestyle habits you can start right now to reduce your risk or reverse symptoms, and why we need to look at bacteria as a cause of neurodegenerative disease.    Dr. Marwan Sabbagh is a board-certified neurologist and considered one of the leading experts in Alzheimer’s and dementia. He is on the editorial board for the Journal of Alzheimer's Disease and BMC Neurology and is now Editor-in-Chief of Neurology and Therapy. Dr. Sabbagh is the author of The Alzheimer’s Answer: Reduce Your Risk and Keep Your Brain Healthy and The Alzheimer’s Prevention Cookbook: 100 Recipes to Boost Brain Health. His latest book, Fighting for My Life: How to Thrive in the Shadow of Alzheimer’s, is now available. Dr. Richard Isaacson serves as Director of the Center for Brain Health and Director of the Alzheimer’s Prevention Clinic (APC) at Florida Atlantic University’s Schmidt College of Medicine. He previously served as Director of the APC at the Weill Cornell Memory Disorders Program, Assistant Dean of Faculty Development, and Associate Professor of Neurology at Weill Cornell Medicine and New York-Presbyterian. He remains as Adjunct Associate Professor of Neurology in the Department of Neurology at Weill Cornell.  Dr. Jay Lombard is an internationally acclaimed neurologist, author, and keynote speaker specializing in neuroimmunological conditions and medical mysteries. Dr. Lombard integrates biological, psychological, and existential components in his holistic treatment approach. Dr. Lombard’s clinical experience revealed an interesting pattern: one patient with ALS also had small-intestine bacterial overgrowth, another had ulcerative colitis, yet another had Crohn’s, and so on. He started seeing the connections between these bacterial imbalances and Clostridium difficile, or C. diff, and the link to neurological symptoms.   This episode is brought to you by Athletic Greens and ButcherBox.
