Air pollution and Alzheimer's disease research has uncovered groundbreaking mechanisms showing exactly how environmental toxins contribute to memory loss and neurodegeneration. Scientists at Scripps Research discovered that a chemical process called S-nitrosylation, triggered by pollutants in air pollution, smoke, and pesticides, disrupts brain cell function by preventing new neural connections. Remarkably, when researchers blocked this process in Alzheimer's mouse models, they partially reversed memory loss, opening new pathways for potential drug treatments. Explore the compelling evidence linking air pollution to cognitive decline and the promising therapeutic approaches emerging from this research.
