Your Brain On... Lyme Disease
A tiny bite from a tiny tick can trigger a complex disease which speaks to some huge problems with our healthcare system. In this episode, we explain the biology, controversy, and cultural blind spots around Lyme disease, a condition that reflects much more than just a bacterial infection. It’s also a mirror for our most urgent public health issues: inequality, misinformation, climate change, and the growing mistrust of science. We speak with two world-class experts: • Dr. John Aucott: Director of the Johns Hopkins Lyme Disease Clinical Research Center and leading voice on post-treatment Lyme disease syndrome (PTLDS) • Dr. Richard Marconi: Professor of microbiology and immunology at Virginia Commonwealth University, and a pioneering scientist behind next-generation Lyme vaccines Together, we explore: • Why Lyme disease symptoms can linger long after treatment • What makes Lyme so neurologically disruptive (and so hard to diagnose) • How climate change, suburban development, and racial disparities intersect with the rise of tick-borne illness • The dangers of alternative medicine grifters preying on desperate patients • The truth about the original Lyme vaccine, and what’s coming next... We also share practical prevention tips and discuss how Lyme disease is shaping the future of infectious disease research, diagnostics, and brain health. This is... Your Brain On Lyme Disease. ‘Your Brain On’ is hosted by neurologists, scientists, and public health advocates Ayesha and Dean Sherzai. SUPPORTED BY: NEURO World.

Your Brain On... Gluten
Gluten has become one of the most misunderstood aspects of modern nutrition. Let’s set the record straight. In this episode, we untangle the medical, neurological, and cultural narratives surrounding gluten, from celiac disease and non-celiac gluten sensitivity to real (and rare) cases of gluten-induced brain dysfunction. We discuss: • The differences between celiac disease, gluten sensitivity, and wheat allergy • How gluten affects the gut, and what ‘leaky gut’ really means • Whether gluten can trigger neurological symptoms like ataxia and brain fog • Why cutting out gluten without a diagnosis may do more harm than good • How wheat contributes to a healthy microbiome (and why fiber matters) • What role zonulin plays in gut permeability and immune activation • Why brain fog isn’t yet well understood (and the theories behind it) To help us decode the science (and bust the myths) of gluten, nutrition, and the brain, we’re joined by two world-renowned experts: DR. ALESSIO FASANO: pediatric gastroenterologist, research scientist, and chief of Pediatric Gastroenterology and Nutrition at Mass General for Children (MGfC), and director of the Center for Celiac Research. DR. FRANK CUSIMANO: gastroenterologist, physician-scientist, and gut-brain health communicator with a PhD in Nutritional and Metabolic Biology from Columbia University Institute of Human Nutrition. This is... Your Brain On Gluten. ‘Your Brain On’ is hosted by neurologists, scientists and public health advocates Ayesha and Dean Sherzai. ‘Your Brain On...

Two-thirds of those diagnosed with Alzheimer’s disease are women — but why? In this episode, we unpack the neurological, hormonal, and social drivers that uniquely affect women's brain health during the menopausal transition — from estrogen’s protective role in the brain to the misunderstood history of hormone replacement therapy. We discuss: • Why women face a higher risk of Alzheimer’s than men • How menopause accelerates brain aging (and how it starts earlier than is often expected) • The role of estrogen in brain metabolism and neuroprotection • The real story behind hormone replacement therapy (HRT) • The impact of genes like APOE4 on women’s brain health • How lifestyle factors like stress, sleep, and cognitive activity can help reduce the impact of neurological changes onset by menopause ——— Get our free curation of women’s brain health resources in our Brain Box: http://thebraindocs.com/brainbox ——— To help us tell this story, we welcome three world-renowned women’s health experts to the podcast: DR.
