In this eye-opening episode, we dive into one of the most alarming environmental health discoveries of our time: microplastics are infiltrating our brains—and the implications for cognitive health may be profound. 

Our conversation with Dr. Matt Campen, a distinguished professor and toxicologist, and Dr. Eliane El Hayek, an assistant professor at the forefront of microplastic research helps us unravel the science behind how these tiny plastic particles enter our bodies, cross the blood-brain barrier, and potentially contribute to neurological decline. 

From the water we drink to the air we breathe, microplastics are everywhere—and emerging research suggests they may be accumulating in brain tissue at concerning levels. Our guests explain the latest findings, the potential mechanisms of harm, and what this means for dementia risk and brain health across the lifespan.
