摘要

As the global incidence of neurodegenerative disorders rises at a rate beyond what can be attributed solely to population aging, the role of modifiable risk factors has come into research spotlight to inform preventive strategies. While many lifestyle interventions can be implemented at an individual level, addressing environmental pollutants that drive neurodegeneration requires a collective effort involving both public and political engagement. This narrative review summarizes current evidence on the role of selected environmental toxins—pesticides, solvents, air pollution, and heavy metals—in the development of Parkinson’s Disease, Alzheimer’s Disease, and Amyotrophic Lateral Sclerosis. Drawing from epidemiological and experimental studies, we highlight associations between these exposures and neurodegeneration, as well as potential converging pathophysiological mechanisms such as neuroinflammation and proteinopathy. Understanding these links may help inform public health measures aimed at reducing the burden of these diseases.
