According to the Centers for Disease Control and Prevention (CDC), the prevalence of people with a Parkinson's diagnosis is about 1% for people 60 years of age. This increases to around 4% by age 80.
However, certain factors, such as genetics and exposure to environmental toxins, can increase the risk of a person developing Parkinson's.
There are things that a person can do that may reduce the risk of developing PD. These include making dietary changes, exercising regularly, and avoiding toxic chemicals.
