Summary

This scoping review protocol maps scientific evidence on the presence of micro- and nanoplastics in the brain, their neurotoxic effects, and implications for human health, drawing from both human studies and experimental models. The protocol follows JBI methodology to systematically chart available evidence.

This scoping review protocol aims to map the scientific evidence on the presence of micro- and nanoplastics in the brain, their neurotoxic effects, and potential implications for human health. Evidence from human studies and experimental models will be systematically charted following JBI methodology and PRISMA-ScR guidelines to identify key mechanisms, affected brain regions, and knowledge gaps.
