Send us Fan Mail How does toxic Tau leave the brain? In this editorial, Vincent Prévot and colleagues spotlight tanycytes—specialized cells lining the third ventricle that shuttle Tau from cerebrospinal fluid into the blood. In Alzheimer's disease these cells are fragmented and their transport genes look dysregulated, which may worsen Tau buildup and open a new therapeutic angle. Source: Prév...

Send us Fan Mail Should doctors check brain health the way they check blood pressure? In this editorial, neurologist Gregory Cooper looks at the Brain Health Vital Signs project, which scores patients on 15 lifestyle risk factors for dementia. He explains how the FINGER, US POINTER, and LatAm-FINGERS trials showed that exercise, diet, mental challenge, social connection, and heart health can prote...

Send us Fan Mail Even patients chasing new Alzheimer's antibody drugs often skip the lifestyle basics that protect the brain. A Brain Health Vital Signs study of 150 people with early Alzheimer's found fewer than 3% met all 15 consensus recommendations, with the biggest gaps in exercise, mood and stress, blood sugar, blood pressure, and weight. Those pursuing anti-amyloid therapy looked...

Send us Fan Mail Most brain-healthy diet advice, like the Mediterranean and MIND diets, comes from studies of Western populations. In this editorial, Lei Feng of the National University of Singapore responds to a new review of diet and Alzheimer's risk across East and West. He highlights the Shanghai Cognitive Diet Pattern, which is built around what Chinese adults actually eat, and explains...

Send us Fan Mail Does what you eat shape your risk of Alzheimer's disease, and does the answer change between Eastern and Western diets? This episode digs into a 2026 review in the Journal of Prevention of Alzheimer's Disease that compares dietary patterns across East and West, including the Mediterranean and MIND diets and traditional Asian eating patterns, and what the evidence says ab...

Send us Fan Mail People with atrial fibrillation (AFib), a common irregular heart rhythm, face a higher risk of developing dementia. This study followed 91,795 UK Biobank participants who wore activity trackers. It found that people with AFib who got at least 150 minutes a week of moderate-to-vigorous activity had a lower AFib-related dementia risk. Interestingly, the activity people reported them...

Send us Fan Mail Your brain’s future might be readable from your cardiovascular risk score right now. We walk through a dense but deeply practical research paper from the Journal of Prevention of Alzheimer’s Disease that links 10-year ASCVD risk to the pace of cognitive decline, without needing a brain scan to spot the warning signs. The big idea is simple: cognitive preservation is not just a neu...

Send us Fan Mail You know that moment when you open the refrigerator and forget what you came for, or you recognize an actor’s face but their name is gone? Most of us laugh it off, but the fear behind it is real: what if it’s not stress or sleep, but the earliest sign of Alzheimer’s disease? We break down a landmark 2026 study that asks a surprisingly uncomfortable question: who is the more reliab...

Send us Fan Mail You can “pass” a memory test and still reveal something chilling: your brain can confidently invent a word that was never said. We start there because that tiny intrusion error, caught by the right kind of neuropsychological scoring, may be one of the earliest objective signals of Alzheimer’s disease long before you lose your keys or miss an appointment. We unpack a 2026 narrative...

Send us Fan Mail Imagine learning that your brain is on a specific trajectory toward memory loss and you find out from a routine blood draw, not a spinal tap, not a hard-to-access PET scan. That future is arriving fast, and it’s creating a new challenge: we don’t have one “Alzheimer’s blood test” anymore. We have a growing menu of brain biomarkers, each reporting on a different kind of cellular cr...

Send us Fan Mail Alzheimer’s has been treated like a neuron problem for decades, but what if the real lever sits in the brain’s support system, quietly failing long before symptoms show up? We dig into a 2026 Journal of Prevention of Alzheimer’s Disease paper that uses a massive transcriptomic dragnet across multiple human datasets to spotlight one surprising hub: CD44, a receptor best known outsi...

Send us Fan Mail In the European Union, the Alzheimer's drug donanemab is approved for a narrower group of people with early symptomatic Alzheimer's disease. They must carry no copies or one copy of the APOE ε4 gene variant, and they can't have certain signs of brain bleeding, uncontrolled high blood pressure, or be taking blood thinners. This analysis of the TRAILBLAZER-ALZ 2 trial...

Send us Fan Mail Your shoulders creep toward your ears during a brutal month. Your chest tightens during panic. Your body feels heavy during depression. We usually call those downstream symptoms, but the research we’re unpacking argues for something far more disruptive: fascia may help generate the very emotional states we blame on the brain alone. We walk through a major 2026 review that reframes...

Send us Fan Mail 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 f...

Send us Fan Mail 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,...

Send us Fan Mail 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 hi...

Send us Fan Mail 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 bloc...

Send us Fan Mail 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...

Send us Fan Mail 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 rel...

Send us Fan Mail 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 adu...

Send us Fan Mail 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 de...

Send us Fan Mail 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...

Send us Fan Mail 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...

Send us Fan Mail 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 bi...
