What causes Parkinson’s disease?


The cause of Parkinson’s disease is unknown; however, both genetic and environmental factors may play a role.

Some people are more likely to develop Parkinson’s disease. Factors that may increase risk include:

  • Age 60 and older
  • Having a close relative with the disease
  • Male sex – men are more likely than women to develop Parkinson’s disease
  • Exposure to toxins such as pesticides
  • Rural living
  • Drinking well water
