Risk Factors for Parkinson’s Disease
A risk factor is something that increases your likelihood of getting a disease or condition.
It is possible to develop
Risk factors include:
Most people develop Parkinson’s disease after the age of 60 (age of onset ranges from 35-85). It is relatively unusual to develop Parkinson’s disease before the age of 40, although it is certainly possible.
Men are about 1.5 times more likely than women to develop Parkinson’s disease.
More than half a dozen genes have been associated with Parkinson's disease. People with these abnormal genes tend to develop Parkinson's disease at a younger age, typically before the age of 50. This type of Parkinson's tends to run in families. However, the vast majority of Parkinson's disease occurs in older individuals (over the age of 60), and the role of genetics in these individuals is less clear.
Research suggests that blacks and Asians have a slightly lower rate of Parkinson’s disease than whites.
Exposure to chemicals, such as herbicides and pesticides, is thought to increase your risk of developing Parkinson’s disease. You also have a greater risk of Parkinson’s disease if you live in a rural area, drink well water, or live on a farm (perhaps due to an increased exposure to herbicides and pesticides).
