Summary

This scoping review protocol outlines a systematic approach to mapping scientific evidence on the presence of micro- and nanoplastics in the brain, their neurotoxic effects, and potential implications for human health. The review will chart findings from both human studies and experimental models to identify key mechanisms, affected brain regions, and knowledge gaps in this emerging field.

Body Systems

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.

Micro- and Nanoplastics in the Brain: A Scoping Review Protocol on Their Presence, Neurotoxic Effects, and Implications for Human Health

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.

Insights into the toxic effects of micro-nano-plastics on the human brain and their relationship with the onset of neurological diseases: A narrative review.

This review examined toxic effects of micro and nano-plastics (MNPs) on the human brain, linking MNP exposure to neuroinflammation, oxidative stress, disruption of the blood-brain barrier, and progression toward neurodegenerative diseases. The authors synthesized evidence from cell studies, animal models, and emerging human data.

Systematic Review Tier 1

A systematic review of the potential neurotoxicity of micro-and nanoplastics: the known and unknown

This critical review of 234 studies found that micro- and nanoplastics can reach the brain via olfactory translocation or by crossing the blood-brain barrier, where they may cause neuroinflammation, oxidative damage, and behavioral changes in animal models. The evidence raises significant concerns about potential neurotoxic effects of chronic microplastic exposure in humans, though major knowledge gaps remain.

The Urgent Need to Assess and Prevent the Deposits of Microplastics and Nanoplastics in Our Brain

This peer-reviewed commentary argues for urgent research into the deposition of microplastics and nanoplastics in the human brain, calling for standardized methods and more investigation into potential neurological consequences.

Impact of micro- and nanoplastics exposure on human health: focus on neurological effects from ingestion

This review compiles emerging evidence on how ingested microplastics and nanoplastics may affect the brain and nervous system. Researchers found that these particles can disrupt gut bacteria, cross the blood-brain barrier, and accumulate in neural tissue, potentially triggering inflammation, oxidative stress, and protein changes linked to cognitive problems. The study highlights an urgent need for more human research, as initial findings have associated elevated plastic particle levels in brain tissue with neurological concerns.
