Release Date: 11/20/2024

Your Brain On

Behind the staggering statistics on global diabetes prevalence are millions of individuals with different stories, struggles, and solutions. In this episode, we explore how diabetes affects your brain, body, and cognition, and how it can be prevented, managed, and (in many cases) reversed. We share some powerful personal stories from the clinic, bust some persistent food myths, and learn why diabetes is as much a neurological emergency as a metabolic one. Plus, we speak to three leading experts who are changing the way we treat diabetes: BRENDA DAVIS, RD: renowned dietitian and global...

Your Brain On... Alzheimer’s (Mythbusting Special)

Your Brain On

Alzheimer’s disease is constantly surrounded by myths and misinformation. Let’s set the record straight. In this episode, we bust through the most persistent Alzheimer’s myths, with facts based on decades of clinical experience and cutting-edge research. Myths include: • “Alzheimer’s is inevitable in old age” • “It’s all genetic, and there’s nothing you can do” • “There’s no cure, so diagnosis is useless” • “Supplements and vitamins can prevent or cure Alzheimer’s” • “Statins and vaccines cause Alzheimer’s” Plus many others. We also share our...

Your Brain On... Purpose (Sherzai Family Special)

Your Brain On

With big changes happening in the Sherzai family household, we sat down for a roundtable discussion about the concept that will shape what we’re all doing next: our purpose. In this ‘unplugged’ mid-season chat, we’re joined by our kids — Sophia and Alex! — for a wide-ranging conversation about our values and goals. How they form, how they falter, and how they evolve, in an increasingly noisy world. Together, we discuss: • The neurological and evolutionary importance of purpose • How a firm sense of purpose can help us develop better habits • The difference between...

Your Brain On... Creatine

Your Brain On

Creatine for Alzheimer’s — let’s separate the hype from the hope. A new study has caused a stir in June 2025, but lead researcher Matthew K. Taylor told us: “ I don’t think I can recommend it to a patient that this is going to ultimately have some sort of cognitive influence.” We speak to Dr. Taylor and Dr. Russell Swerdlow in this episode, discussing: • Role of creatine in your brain, and why it matters for energy metabolism • What the 2025 study found (and why it wasn’t designed to prove effectiveness) • How scientific nuance gets lost in supplement hype • Why even...

Your Brain On... Stress

Your Brain On

Stress isn’t just a threat to your brain. It’s also one of its best tools for growth. We often hear that stress is bad for your brain. And it can be. Chronic, unpredictable, and uncontrollable stress can damage cognition, harm memory, and accelerate aging. But we don’t talk enough about how the right kind of stress can actually improve brain function, grow your hippocampus, and help you feel happier and more purposeful. In this episode of Your Brain On..., we explore the science of stress with two brilliant guests: Dr. Sharon Bergquist, Yale- and Harvard-trained internal medicine...

Your Brain On... Stroke

Your Brain On

Stroke is one of the biggest causes of death in the world — but also one of the most preventable. Up to 80–90% of strokes could be avoided with more awareness, resources, and a firmer focus on prevention over intervention. In this episode, we’re joined by renowned stroke neurologist and public health pioneer Dr. Olajide Williams, MD, MS, whose ‘Hip-Hop Stroke’ movement is a shining example of enacting culturally-sensitive community-wide healthcare change. In this episode, we discuss: • What actually causes a stroke (and how to spot one in seconds using the ‘act FAST’ acronym)...

Your Brain On... The Food Industry

Your Brain On

How can we eat better when we’re constantly marketed to in a way that hijacks our attention and habits? To complement the incredible discussions we regularly have about brain-healthy nutrition, in this episode, we’ve having a very important conversation about how the food industry works against our best intentions, and how we can break through the psychological barriers they use to hold us back. We’re joined by Marion Nestle, Professor of Nutrition, Food Studies, and Public Health, Emerita, at New York University, whose name is practically synonymous with food policy: a pioneering...

Your Brain On... Lyme Disease

Your Brain On

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...

Your Brain On... Brain-Computer Interfaces

Your Brain On

Restoring a person’s ability to speak, enabling individuals with paralysis to regain movement, and detecting neurodegenerative diseases earlier than ever — these are just some of the breakthroughs brain-computer interfaces are making possible. In this episode, we explore the astonishing world of BCIs: technologies that are giving autonomy and independence back to people with diseases like ALS. We discuss: • How BCIs are helping people with neurodegenerative diseases and spinal cord injuries communicate using decoded brain signals • How brain-computer interfaces actually work (and...

Your Brain On... Gluten

Your Brain On

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...

More Episodes

From the first spark of attraction, all the way to climax, sex sets off chemical fireworks in your brain.

And yet, this beautiful, powerful act has become mired in shame and stigma. But through open conversation and deeper scientific understanding, we can cast off those shackles, and even embrace sex as a marker for cognitive and overall health.

In this episode of ‘Your Brain On...’ — our Season 4 debut! — we discuss:

• The neurological processes involved with sex, arousal, attraction, and desire
• Why studying the cognitive effects of sexual stimuli can be so complicated
• How our relationship with sex is altered as we age, and is affected by periods of change like menopause
• The neuroscientific differences between masturbation and sex with a partner
• The complex debate about pornography consumption, and the need for better sex education
• The links between brain health, heart health, mental health, and sexual health
• The benefits of good nutrition, exercise, and stress management for sexual health
• Motivations and methods for freeing conversations about sex from stigmas and taboos — especially for women

Joining us for this immensely important conversation are two fantastic guests: sexual behaviour expert and data scientist Dr. Nicole Prause, and sexual medicine expert and urogynecologist Rena Malik.

This is... Your Brain On Sex.

‘Your Brain On’ is hosted by neurologists, scientists and public health advocates Ayesha and Dean Sherzai.
