#88: Are Microplastics Causing Dementia?

38 min4 november 2025

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!
