Alzheimer’s Starts Decades Before Symptoms

Stop Blaming Your Teen: The Science Behind the Teenage Brain

Why do teenagers act the way they do? Is it just defiance, or is there a biological "system update" happening under the hood? In this final episode of our three-part series, we sit down with neuroscientist and bestselling author Dr. Dean Burnett to demystify the teenage brain. We move past the "25-year-old cutoff" myth and explore why adolescence is a period of massive neurological "decluttering" and architectural upgrades. Dr. Burnett explains why the teenage brain is physically wired to prioritize peer approval, why emotions feel so much more intense during these years, and how childhood experiences, especially those around age four, lay the foundational identity that we carry into adulthood. If you’ve ever felt confused by your own teenage years or are currently navigating them, this episode provides a clear, empathetic, and scientifically grounded look at how we become who we are.

Why Habits Feel Impossible to Break

Why is it so easy to pick up a bad habit and so grueling to break one? And why does willpower always seem to fail us when we need it most? In this episode, I’m joined once again by neuroscientist and bestselling author Dr. Dean Burnett to break down the mechanics of habits, cravings, and addiction. We explore why habits become "automated" like riding a bike, how addiction creates a biological "arms race" in your reward system, and the truth behind our relationship with social media and smartphones. Dr. Burnett explains why passive scrolling feels so "brain-numbing" and provides actionable, science-backed strategies to help you reprogram your routines by working with your biology instead of against it.

The Truth About Sleep

What if your brain is still working almost as hard during sleep as when you are awake? And what actually happens when you do not get enough sleep? In this episode, I’m joined by Dr. Dean Burnett, neuroscientist and bestselling author of The Idiot Brain and The Happy Brain, to break down the science of sleep, stress, and burnout. We explore what sleep is actually doing for the brain, why sleep deprivation leads to cognitive breakdown, and how stress builds up into burnout over time. Dr. Burnett explains why sleep is essential for memory, why “sleep debt” is not easily fixed, and how chronic stress physically affects the brain. This episode offers a clear understanding of how your brain handles sleep, stress, and performance, and what happens when those systems are pushed too far. Hosted by Avanish Srinivasan.

Alzheimer’s Starts Decades Before Symptoms

What if Alzheimer’s disease begins decades before symptoms and you wouldn’t even know? In this episode, I’m joined by Dr. Adam Brickman, Professor of Neuropsychology at Columbia University, to break down how the brain actually ages and what’s really happening in Alzheimer’s disease. We explore the difference between normal cognitive aging and neurodegeneration, why dementia and Alzheimer’s are not the same, and how biological changes like amyloid plaques can exist long before symptoms appear. Dr. Brickman also explains why removing these plaques doesn’t necessarily cure the disease, and how factors like vascular health, lifestyle, and socioeconomic conditions shape cognitive decline. This episode offers a clearer, more accurate understanding of brain aging and what it means for prevention, treatment, and the future of neuroscience. Hosted by Avanish Srinivasan.

Reality Is a Prediction

Have you ever realized that you and someone else can look at the exact same thing and see completely different realities? From the viral dress illusion to the subtle psychology behind blue vs. green text bubbles, perception isn’t objective. It’s constructed. In this episode, I’m joined by Dr. Elizabeth (Zab) Johnson, Executive Director of the Wharton Neuroscience Initiative at the University of Pennsylvania, to break down how visual perception actually works and how it quietly shapes the decisions we make every day. We explore why perception is inherently subjective, how your past experiences bias what you see, and why optical illusions aren’t tricks but windows into how the brain resolves uncertainty. We unpack why color can change emotions, decisions, and even financial risk-taking, how celebrities influence choices without us realizing it, and why two people can genuinely disagree about what they’re seeing—without either being wrong. This episode will fundamentally change how you think about vision, choice, and reality itself. Hosted by Avanish Srinivasan. Learn more at youngaxons.com [http://youngaxons.com].
