Microplastics can block blood vessels in mice brains, researchers find
Summary
A new study shows that microplastics can travel through the brains of mice and block blood vessels, mimicking blood clots and reducing motor function. Researchers used real-time imaging to track fluorescent-coated polystyrene particles, which accumulated in brain vessels like a “car crash.” The study found that these blockages persisted for weeks and led to impaired movement and memory. While the findings suggest serious risks to brain health, scientists caution that human effects remain uncertain due to differences in blood flow and vessel size. Microplastics, known to cross the blood-brain barrier, are linked to neurotoxicity and diseases like Parkinson’s. Researchers call for urgent studies on microplastics' impact on human health.
