Dr. Joseph Mercola - Take Control of Your Health This Widely Used Pesticide May Raise Your Parkinson's Risk by Over 2.5 Times
Feb 25, 2026
New research links long-term chlorpyrifos exposure to a more than 2.5-fold increase in Parkinson's risk. They discuss how widespread pesticide use shifts a toxin into a public health problem. Conversation covers dopamine-related neurobiology, the toxin-bucket concept of cumulative exposures, and practical steps like choosing organic and improving indoor air and water.

Episode notes
Widely Used Pesticide Dramatically Raises Parkinson Risk
- A widely used pesticide was linked to more than a 2.5-fold increase in Parkinson's risk.
- A 2.5x relative risk moves this from noise to a strong mechanistic signal affecting broad populations when exposure is common.
Parkinson's Is Movement And Cognitive Collapse
- Parkinson's impacts movement, coordination, and cognitive function, not just tremor.
- Dopamine loss underlies both motor symptoms and executive dysfunction, linking neuron damage to thinking as well as moving.
Environment Pulls The Trigger On Genetic Susceptibility
- New studies shift blame from pure genetics and aging toward environmental exposures.
- The environment has changed rapidly while the human genome hasn't, explaining rising neurological disease incidence.
