Neurotoxicity of microplastic particles in the human brain: a systematic review
AI summary Read the abstract
This systematic review examines how microplastic particles may affect the human brain and nervous system. The research found that microplastics can reach the brain and cause changes in behavior and thinking, though more studies are needed to understand the long-term effects. This is an early but important signal that plastic pollution could impact brain health.
MPs are a significant global health problem. With the widespread use and accumulation of plastic materials, MPs can reach the nervous system and exert neurotoxic effects manifesting in behavioral and cognitive changes. The current evidence is insufficient to delineate the possible long-term outcomes of MP exposure. Further clinical studies are warranted to elucidate the mechanisms underlying these neurotoxic effects.

Impact of micro- and nanoplastics exposure on human health: focus on neurological effects from ingestion
AI summary Read the abstract
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.
A systematic review of the potential neurotoxicity of micro-and nanoplastics: the known and unknown
AI summary Read the abstract
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.
Effects of microplastics and nanoplastics on the brain and behavior: Evidence from rodent and human studies
AI summary Read the abstract
Tiny plastic particles that have already made their way into our bodies may do more than harm the heart and lungs, this review pulls together research suggesting they could also affect the brain and behavior, based on studies in animals, human data, and lab-grown brain tissue. While scientists are still working out exactly how much risk this poses to people, the early evidence is concerning enough that researchers say understanding these effects on brain health should be a priority as plastic pollution keeps growing.
The neurotoxic threat of micro- and nanoplastics: evidence from In Vitro and In Vivo models
AI summary Read the abstract
This systematic review examined 26 studies showing that micro- and nanoplastics can cross into the brain, damage neurons, and trigger inflammation in lab and animal models. These findings raise concerns that long-term plastic exposure could contribute to neurological problems in humans, though more research is needed.
A systematic review of the potential neurotoxicity of micro-and nanoplastics: the known and unknown
AI summary Read the abstract
This systematic review summarizes 234 research studies on how micro- and nanoplastics may harm the brain and nervous system. Evidence from animal and lab studies suggests these particles can reach the brain, potentially through the nose or by crossing the blood-brain barrier, and may cause inflammation and damage to nerve cells.
