Therapeutic Strategies to Ameliorate Neuronal Damage in Epilepsy by Regulating Oxidative Stress, Mitochondrial Dysfunction, and Neuroinflammation
Summary
This review explores new treatment approaches for epilepsy that target oxidative stress, mitochondrial problems, and brain inflammation. While not directly about microplastics, these same biological pathways (oxidative stress and inflammation) are triggered by microplastic exposure in the brain. The findings are relevant because they help explain how environmental pollutants like microplastics could worsen neurological conditions.
Epilepsy is a central nervous system disorder involving spontaneous and recurring seizures that affects 50 million individuals globally. Because approximately one-third of patients with epilepsy do not respond to drug therapy, the development of new therapeutic strategies against epilepsy could be beneficial. Oxidative stress and mitochondrial dysfunction are frequently observed in epilepsy. Additionally, neuroinflammation is increasingly understood to contribute to the pathogenesis of epilepsy. Mitochondrial dysfunction is also recognized for its contributions to neuronal excitability and apoptosis, which can lead to neuronal loss in epilepsy. This review focuses on the roles of oxidative damage, mitochondrial dysfunction, NAPDH oxidase, the blood-brain barrier, excitotoxicity, and neuroinflammation in the development of epilepsy. We also review the therapies used to treat epilepsy and prevent seizures, including anti-seizure medications, anti-epileptic drugs, anti-inflammatory therapies, and antioxidant therapies. In addition, we review the use of neuromodulation and surgery in the treatment of epilepsy. Finally, we present the role of dietary and nutritional strategies in the management of epilepsy, including the ketogenic diet and the intake of vitamins, polyphenols, and flavonoids. By reviewing available interventions and research on the pathophysiology of epilepsy, this review points to areas of further development for therapies that can manage epilepsy.

Elucidating the Neurotoxicopathological Impact of Micro and Nanoplastics: Mechanistic Insights Into Oxidative Stress-mediated Neurodegeneration and Implications for Public Health in a Plastic Pervasive Era
Researchers reviewed the growing evidence linking micro- and nanoplastic exposure to neurodegenerative diseases, identifying oxidative stress, neuroinflammation, DNA damage, and protein misfolding as key mechanisms of harm to the brain. The review highlights critical knowledge gaps — especially around chronic low-dose exposure — and calls for better detection tools and public health policies to address the emerging neurological threat from plastic pollution.
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.
Pathways, Mechanisms, and Therapeutic Strategies of Neurotoxicity Induced by Micro- and Nanoplastics
This review examined the pathways by which micro- and nanoplastics reach the brain—via the gut-brain axis, respiratory tract, and circulatory system—and the mechanisms by which they induce neurotoxicity, including neuroinflammation, oxidative stress, and disruption of neurotransmitter systems. The authors surveyed emerging therapeutic strategies, highlighting antioxidant supplementation and anti-inflammatory interventions as the most promising current approaches.
Uncovering the impact of nano- and microplastics on neurodegenerative diseases and strategies to mitigate their damage
Researchers reviewed evidence that micro- and nanoplastics may contribute to the progression of Alzheimer's and Parkinson's diseases by triggering brain inflammation, disrupting mitochondria (the cell's power source), and damaging the blood-brain barrier. The review also found that natural compounds like melatonin and probiotics show early promise in reducing some of these harmful effects.
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.
