The latest study, published on Sept. 16 in JAMA, identifies microplastics in the olfactory bulb—the region of the brain located above the nose and responsible for our sense of smell. This discovery raises new concerns that these tiny particles might be slipping past the brain’s protective barriers and enter deeper brain regions, potentially harming brain health and neurological function.
“Our analysis of olfactory bulbs from deceased patients in São Paulo confirmed the presence of microplastics,” physician and principal investigator Thais Mauad told The Epoch Times. This suggests a potential route for these particles to enter the brain.
Mauad also highlighted the uncertainty surrounding the health effects of these findings. “We still don’t know the consequences,” she said, noting that animal studies suggest potential neurotoxicity and links to neurodegenerative diseases.
While microplastics have been found in various body tissues, including the lungs, gut, liver, placenta, testicles, and bloodstream, research on their health risks is still in its early stages. More studies are needed to understand the potential health impacts.
