Deciphering the Neurotoxic Burden of Micro- and Nanoplastics: From Multi-model Experimental Evidence to Therapeutic Innovation
This review summarizes research on how micro- and nanoplastics damage the brain and nervous system, covering evidence from cell studies, animal experiments, and clinical observations. Plastic particles can cross the blood-brain barrier, disrupt the gut-brain connection, cause oxidative stress, and trigger inflammation that leads to memory problems and cognitive decline. The review also discusses potential treatment strategies, making it a useful resource for understanding the brain health risks of plastic exposure.
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.
Microplastics and the gut-brain axis: Unraveling neurotoxic mechanisms and health implications
This review examines how microplastics interact with the gut-brain axis, a communication network linking the digestive system to the central nervous system. Researchers found that microplastics can disrupt intestinal barrier integrity, alter gut microbiota composition, and trigger systemic inflammation that may affect neurotransmitter balance and brain function. The study suggests that chronic microplastic exposure through the diet could contribute to neurological effects through inflammatory and oxidative stress pathways.
Microplastics/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.
An overview of research on the association between microplastics and central nervous system disorders
This review explores the growing body of evidence linking microplastic exposure to central nervous system disorders. Researchers found that microplastics can enter the body through ingestion, inhalation, and skin absorption, then accumulate in neural tissues where they trigger inflammation, oxidative stress, and neuronal damage. The study aims to provide a scientific foundation for assessing the public health risks of microplastic exposure on brain health.
Neurotoxicities induced by micro/nanoplastics: A review focusing on the risks of neurological diseases
This review summarizes evidence that micro- and nanoplastics can reach the brain through the bloodstream and nerve pathways, where they trigger oxidative stress, inflammation, and cell damage that may contribute to neurodegenerative diseases. The particles are found in air, water, soil, and food, meaning humans are constantly exposed through breathing, eating, and skin contact, making brain effects a serious long-term concern.
From exposure to neurotoxicity induced by micro-nanoplastics with brain accumulation and cognitive decline
This review synthesizes evidence that micro- and nanoplastics can reach the brain by crossing the blood-brain barrier or traveling along nerve pathways, accumulating in regions critical for memory and thinking. Animal studies show that chronic exposure leads to cognitive problems, behavioral changes, and brain changes resembling neurodegenerative diseases, driven by oxidative stress, inflammation, and disruption of the gut-brain connection. The findings raise concern that long-term human exposure to nanoplastics through food and air could contribute to cognitive decline and neurological disease.
Brain under siege: the role of micro and nanoplastics in neuroinflammation and oxidative stress
This review examines emerging evidence that micro- and nanoplastics can cross the blood-brain barrier and accumulate in nervous tissue, potentially triggering neuroinflammation and oxidative stress. Researchers summarized findings showing these particles may act as neurotoxicants that contribute to synaptic dysfunction and pathological changes in brain cells. The study highlights the need for further research into how chronic plastic particle exposure may affect central nervous system health over time.

This review examines how nanoplastics can cross the blood-brain barrier and potentially contribute to brain damage and neurodegenerative diseases like Alzheimer's and Parkinson's. Nanoplastics have been found in food, water, and air, and once they reach the brain they can trigger inflammation, oxidative stress, and protein misfolding. The review calls for more realistic lab studies and better detection methods to understand the true scope of nanoplastic effects on brain health.

Neurotoxicity Following Exposure to Micro and Nanoplastics
This review explores how micro and nanoplastics can reach the brain after being swallowed or inhaled, and what neurotoxic effects they may cause.

This review examines evidence that micro- and nanoplastics can cross the blood-brain barrier and cause neurotoxicity through oxidative stress, neuroinflammation, and disruption of neurotransmitter signaling.

Nanoplastic Impact on the Gut-Brain Axis: Current Knowledge and Future Directions
Researchers reviewed the emerging evidence on how nanoplastics may affect the gut-brain axis, the communication pathway between the digestive and nervous systems. Studies indicate that nanoplastic exposure can alter gut microbiota, increase intestinal permeability, trigger oxidative stress and inflammation, and produce neurotoxic and behavioral effects. The review calls for more research given the ubiquitous presence of plastics in the human environment and the potential for nanoplastics to disrupt this critical biological communication pathway.
