Summary

This paper discusses evidence that micro- and nanoplastics may be able to cross the blood-brain barrier, the protective layer that normally keeps harmful substances out of the brain. If confirmed in humans, this could mean plastic particles contribute to neurodegenerative diseases, though more research is needed to understand the extent of this risk.
