Better Brain Fitness with Drs. Josh Turknett and Tommy Wood

Henry Mahncke is the CEO of Posit Science and the creator of BrainHQ , the most researched brain training platform in the world. A neuroscientist who did his PhD with Michael Merzenich, considered the father of adult brain plasticity, Henry has spent two decades translating brain plasticity science into tools that actually improve brain health. In this conversation, we dig into why most brain trai...

Can a shingles vaccine cut your dementia risk by 20%? A series of landmark studies — published in Nature, Cell, and JAMA — say yes. In this episode, Tommy unpacks the research: how natural experiments in four countries produced one of the most compelling signals in dementia prevention, what might explain the effect beyond infection prevention, and what it means for your own vaccination decisions....

A recent study published in Nature Medicine claims a blood test can predict when you'll develop Alzheimer's disease, and it got a lot of attention. But how well does it actually work, and should you rush out and get tested? In this episode, we break down the study behind the headlines to understand what it really shows, where the major limitations lie, and what it means for anyone thinking about g...

In this episode, we discuss a study published in PLOS One that compared living brain tissue to post-mortem brain tissue and found dramatic molecular differences between the two. The findings raise serious questions about decades of Alzheimer's research built on post-mortem analysis and may help explain why pharmaceutical treatments for the disease have been so disappointing Study: A Study of RNA S...

In this episode, we dig into a recent McGill University study on computerized cognitive training and its effects on brain chemistry in older adults. What you'll learn: Why certain brain training games reversed a decade of age-related cognitive decline in just 10 weeks—and how researchers finally measured actual biological changes in the brain The critical difference between activities that genuine...

In this episode, we dive into guidelines to figure out what all the fuss is about, whether that fuss is warranted, and whether we should even be issuing dietary guidelines to begin with! Topics and Questions Covered The updates : A breakdown of the specific shifts regarding protein prioritization, full-fat dairy, and whole grain recommendations. The visual shift in nutrition : The transition from...

Much of what we talk about on Better Brain Fitness resolves around the demand-driven decline model we published. Well...a new study just published in Nature Communications gave that model the best test to date, and the results are pretty darn exciting. So of course we had to do an episode about it! The study looks at the relationship between brain aging and creative activities like music, dance, a...

In this episode, we tackle a question from listener Carolyn in Michigan about the potential cognitive impacts of long-term hearing loss. What You'll Learn: The research linking hearing loss to increased dementia risk and what the evidence actually shows How hearing aids impact the risk of cognitive decline The mechanisms behind why hearing loss might affect brain health Practical strategies for ma...

You may have heard the alarming headline about a recent study that showed the typical brain had about a teaspoon of microplastics inside of it. And that amount appears to be increasing each year. In equally alarming fashion, that same study also revealed that those with dementia had over 5 times the amount of plastic in their brains as those without. Needless to say, it's an issue worth paying att...
