Common pesticide tied to 2.5-fold higher Parkinson's risk in UCLA study

· Science · United States

A UCLA study found that long-term exposure to a common pesticide was linked to more than 2.5 times the risk of Parkinson's disease, according to the report. The scientists also described how the chemical damages brain cells and said they identified a promising way to protect them. The item does not name the pesticide, the size of the study population or the protective approach. Parkinson's is a progressive neurological disease with no cure, and environmental exposures have long been studied as risk factors alongside genetics.

Why it matters：If replicated, the exposure link and the identified protective mechanism would inform pesticide regulation and give neuroprotective drug research a target.

Key points

  • The risk was more than 2.5 times higher with long-term exposure.
  • Researchers also proposed a way to protect brain cells from the damage.
