Episodes
What if the clearest signal about your brain’s future isn’t hidden inside an MRI, but floating in your blood right now? We dig into Neurofilament Light Chain (NFL), a nervous system biomarker that behaves like a smoke alarm for ongoing nerve damage and could help shift brain health from reactive to proactive.
We anchor the story in a remarkable study of 495 Japanese centenarians followed for up to...
You’ve heard the standard dementia prevention script: eat well, sleep more, do the puzzles, and hope for good genes. Then a result lands that doesn’t fit the script at all, a routine shingles vaccine associated with a 33% lower risk of dementia in a real-world study of 1.5 million Medicare patients. We dig into what that finding does and does not mean, why it’s so hard to dismiss, and how it compar...
Alzheimer’s has been sold to all of us as a neuron story: plaques, tangles, and brain cells fading away. But the data we walk through here points to a more unsettling possibility that the real tipping point is structural. When the brain’s blood vessels fail, memory can fall apart even faster, and what looks like “classic Alzheimer’s dementia” may actually be a vascular collapse hiding i...
A medical breakthrough can still fail at the pharmacy counter. We finally have amyloid-targeting drugs for early-stage Alzheimer’s disease, and they are already on the market, but several major health systems have looked at the same evidence and refused to pay. That contradiction is the mystery we unpack, using the explosive Glasgow IPCAD meeting as our guide to what’s really blocking access.
We d...
A camera watches you walk across a room and can estimate your biological age. That sounds like science fiction until you see the data and the logic behind it. We break down a 2026 multidimensional modeling study that replaces the idea of “age as a number” with age as measurable wear and tear across your body and brain, using tools that are surprisingly practical: a marker-free 3D gait camera, a VR eye-tr...
Depression and dementia get talked about like two separate problems, until you ask the uncomfortable question: which one comes first? We dig into a huge 22-year longitudinal study (over 13,000 Americans in the Health and Retirement Study) to figure out whether depressive symptoms are a modifiable dementia risk factor or an early clinical warning sign of Alzheimer’s disease and related neurodegenerative patholo...
Think your daily health choices only matter for your heart and waistline? The research we’re unpacking challenges that assumption and makes a sharper, more urgent claim: the same habits may interact with silent Alzheimer’s pathology in your brain years before any symptom shows up. We walk through a major analysis combining the A4 and LEARN cohorts (1,707 cognitively unimpaired adults ages 65 to 85) and e...
Fish oil has a near-halo status in nutrition culture: a simple, golden capsule that promises better memory, sharper thinking, and protection from cognitive decline. But a landmark longitudinal analysis using ADNI data and published in the Journal of Prevention of Alzheimer’s Disease forces a rethink, suggesting omega-3 supplement use in older adults may be linked to accelerated decline on major cognitive and f...
The data point that stops us cold: at the same level of Alzheimer’s pathology, people living alone can score higher on cognitive testing than people living with others. We walk through a mind-bending April 2026 study that pulls from more than 11,000 participants and asks two deceptively simple questions with enormous stakes for brain health and aging: are you partnered, and do you live alone?
We break d...
Alzheimer’s is coming at the world like a demographic tidal wave and the hardest part is admitting what we still can’t do: there’s no cure. But what we can do is changing quickly, and the most surprising shift is where the real cognitive gains might come from. We dig into a major 2026 Bayesian network meta-analysis spanning 57 randomized controlled trials and 6,737 people, asking one high-stakes qu...
Your most emotionally brutal year might not just be a memory. It may have left a measurable biological footprint on your brain that can shape cognitive health 30 or 40 years from now. We dig into a groundbreaking 2026 paper in the Journal of Prevention of Alzheimer’s Disease that puts real math behind a question people usually treat as “just mental”: how clinical depression and bipolar disorder cha...

What if the biggest lever for preventing dementia isn’t hidden in your DNA, but sitting in your calendar, your sleep, your diet, and even your hearing? We dig into a 2026 German study published in the Journal of Prevention of Alzheimer’s Disease that argues up to 45% of dementia risk is modifiable and then shows what “modifiable” actually looks like when you measure it person by person. ...
Alzheimer’s doesn’t wait for a diagnosis to begin. The brain changes can start quietly for years, even a decade, while someone looks totally fine, passes cognitive tests, drives, works, and pays the same routine healthcare bills as their peers. That raises a tough question with massive public health stakes: if the disease is already active, when does it start costing Medicare real money?
We dig in...
A tiny smudge in a century-old medical paper might be one of the most useful clues we have for Alzheimer’s disease prevention today. We trace that smudge back to 1907, when Alois Alzheimer documented not only plaques and tangles, but also lipid accumulation inside glial cells, a finding the field largely shrugged off for decades. Once you add modern genetics, especially ApoE4 and its role in lipid transport, t...
Your medicine cabinet feels organized for a reason: we like to believe each pill has a single target and stays in its lane. Then we hit a finding that blows up that mental map. Millions of people take statins and other cholesterol drugs to manage LDL and cardiovascular risk, but a massive new dataset suggests those same lipid-lowering regimens may also slow Alzheimer’s disease decline, especially in the years ...
A clean diagnosis feels like an X-ray: obvious problem, obvious fix. Alzheimer’s disease is the opposite, and the arrival of disease-modifying anti-amyloid therapies like lecanemab and donanemab makes that gap impossible to ignore. We dig into why real-world patients do not look like “pristine” clinical trial participants, and why a simple amyloid positive label can hide wildly different biology, r...
Your brain is an energy hog running on an ATP battery that lasts only seconds, and that one fact changes how you should think about “brain supplements.” We dig into why creatine is more than a weightlifting staple, how phosphocreatine works like a built-in power bank, and why the blood brain barrier makes brain saturation slow, picky, and easy to study the wrong way. If you’ve ever tried to boost f...
Sleep turns on a hidden plumbing system that pressure-washes the brain, clearing toxic waste that builds up during wakefulness. We connect brand-new human imaging with practical sleep habits so you can protect deep sleep, memory, and long-term cognitive health.
• why the brain accumulates metabolic waste while awake
• how the glymphatic system works and why science missed it for decades

A probiotic is supposed to help you recover after antibiotics. But what if the wrong probiotic acts like an invasive weed, moves into the empty real estate in your gut, and blocks your native microbiome from growing back? We unpack the science behind that unsettling possibility and use a comprehensive medical review by Dr. Kristen Glorioso to separate real microbiome research from gut health marketing that promises ...
