Better Brain Fitness with Drs. Josh Turknett and Tommy Wood

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, art, and video gaming. Tommy walks through the study and explains why this matters for anyone thinking about their long-term cognitive health.

• A more sensitive way to measure brain aging than structural scans

• The connection between music, dance, art, and video gaming on brain aging

• The effect of 30 hours of video gaming on brain aging, the kinds of video games that have the greatest impact (and why traditional "brain games" haven't been as successful)

• What this research tells us about whether cognitive decline is reversible

• The dose-response relationship between complex activities and brain health

In this episode, we tackle a question from listener Carolyn in Michigan about the potential cognitive impacts of long-term hearing loss.

• 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 maintaining cognitive health when dealing with hearing loss

• Innovative technologies for hearing loss that could provide new forms of cognitive stimulation

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 attention to. So, in this episode, we break down what is known about microplastics and their impact on brain health, and we discuss the specific measures we're both taking to reduce our own exposure to microplastics and enhance their clearance.

Because brain plasticity is a great thing, but a plastic brain is not!
