New research reveals a striking pattern: microplastics accumulate in the human brain at 7–30× higher concentrations than in the liver or kidneys raising concerns about long‑term neurological health.
The inaugural issue of Brain Health synthesizes global evidence showing that brain accumulation has risen nearly 50% in eight years, with the highest loads found in individuals diagnosed with dementia. #Polyethylene—mostly nanometer‑scale fragments—dominates these deposits.
The review connects these findings to broader #cardiovascular risks. A landmark Italian study detected microplastics in carotid artery #plaque, where affected patients faced a fourfold increase in #heart attack, #stroke, or mortality over 34 months. Animal studies reinforce the concern: #polystyrene nanoparticles can cross the blood–brain barrier within two hours, demonstrating how rapidly these particles infiltrate neural tissue.
Researchers identify ultra‑processed foods as a major exposure route, with plastics leaching from packaging and abrasion during manufacturing. Promising early work from Dresden and King’s College London shows that therapeutic apheresis can remove microplastic‑like particles from blood plasma, though clinical application remains distant.
For now, experts recommend a simple, actionable step: reduce ultra‑processed food consumption to limit microplastic exposure.
