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.

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.

Nano- and Microplastics in the Brain: An Emerging Threat to Neural Health

This review summarizes evidence that nano- and microplastics can cross the blood-brain barrier and accumulate in brain tissue, where they trigger oxidative stress, inflammation, and protein clumping linked to diseases like Alzheimer's and Parkinson's. The findings suggest that plastic particles may also interfere with the brain's ability to heal from injury, though long-term human studies are still lacking.

From the Environment to Molecular Interactions of Nanoplastics: Unraveling the Neurotoxic Impacts and the Implications in Neurodegenerative Processes

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. Research shows these tiny particles can cross the blood-brain barrier, similar to metal nanoparticles, and potentially damage brain cells. While the full extent of brain harm from plastic particles is still being studied, early findings raise concerns about long-term neurological effects from everyday exposure.

Micro-nanoplastics in the central nervous system: Evidence, mechanisms and perspectives

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. While clinical studies have confirmed the presence of plastic particles in human brain tissue and cerebrospinal fluid, the authors note that methodological limitations and inconsistent quality controls currently prevent establishing a definitive causal link to neurological conditions.

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.
