A 2026 Australian ecological model found that 20-year-lagged cumulative population blood-lead burden was nonlinearly tied to motor neuron disease mortality (lead spline p = 0.00024), while national insecticide use did not independently explain the curve after adjustment (p = 0.39).1 That is a real lead signal, but it is still population-level evidence, not proof that …
Microplastics and nanoplastics (MNPs) from the breakdown of plastic materials pollute the environment and make their way into the human body, raising concerns over potential health impacts. Research shows that microplastics and nanoplastics are able to cross the blood-brain barrier in mice within 2 hours of ingestion. Key Facts: Polystyrene nanoparticles with a size of …
Fluoride is considered a colorless inorganic anion of the chemical fluorine and is commonly used as an additive in drinking water to improve dental health. Adding fluoride to tap water is a proven method for decreasing rates of tooth decay and cavities. The United States Center for Disease Control markets fluoridation of tap water as being …
Neuroprotective agents refer to substances that are capable of preserving brain function and structure. When the brain is exposed to high levels of oxidative stress, mitochondrial dysfunction, inflammation, various forms of neurotoxicity (e.g. excitotoxicity), and protein deficiencies – neurodegeneration can occur. To prevent or mitigate the effects of any neurodegeneration, strategic administration of a neuroprotective …
