Microplastics may be quietly damaging your brain and fueling Alzheimer’s and Parkinson’s (opens in new tab)

Tiny plastic particles may be quietly threatening brain health. New research suggests microplastics—now widely found in food, water, and even household dust—could trigger inflammation and damage in the brain through multiple biological pathways. Scientists estimate adults may consume about 250 grams of these particles each year, and some can accumulate in organs including the brain.
