Abstract

Microplastics and nano-plastics (MNPs) have become a pervasive environmental pollutant, raising concerns about their potential health effects. This review examines the bioaccumulation of MNPs in human brain tissues and their possible implications for neurodegenerative diseases. The study highlights that brain tissue accumulates higher concentrations of MNPs compared to the liver and kidney, with polyethylene being the most dominant polymer. Additionally, dementia patients exhibit significantly higher MNP levels, suggesting a potential link to neuroinflammation and cerebrovascular pathology. The mechanisms by which MNPs infiltrate the brain, such as blood-brain barrier penetration, are discussed alongside their associated health risks. The article calls for urgent research on MNP exposure routes, long-term health effects, and regulatory actions to mitigate plastic pollution.
