Widely used pesticide linked to more than doubled Parkinson’s risk

A new study from UCLA Health has found that long-term residential exposure to the pesticide chlorpyrifos is associated with more than a 2.5-fold increased risk of developing Parkinson’s disease. The research, published in the journal Molecular Neurodegeneration, combines human population data with laboratory experiments showing how the pesticide damages dopamine-producing brain cells, providing biological evidence for the link.
