ClearMicroplastics/nanoplastics and neurological health: An overview of neurological defects and mechanisms
This review summarizes evidence that micro and nanoplastics can harm the nervous system, causing developmental abnormalities, brain cell death, neurological inflammation, and potentially contributing to neurodegenerative diseases. Animal studies show that these tiny plastics can cross the blood-brain barrier and accumulate in brain tissue, where they trigger oxidative stress and disrupt normal brain function. While direct evidence in humans is still limited, the findings suggest that chronic microplastic exposure could be a risk factor for neurological health problems.
