Common pesticide may more than double Parkinson’s disease risk
ScienceDaily reports UCLA Health findings that long-term chlorpyrifos exposure is linked to more than a 2.5-fold higher likelihood of Parkinson’s disease.
According to the March 15, 2026 ScienceDaily report on UCLA Health research, long-term exposure to chlorpyrifos was associated with substantially higher Parkinson’s disease risk in populations living in persistently exposed areas.
The report also cites laboratory evidence in animals: movement impairment, loss of dopamine-producing neurons, and toxic protein buildup consistent with Parkinson’s pathology after exposure.
