Young Onset Parkinson’s disease (YOPD) occurs in people younger than 50 years of age. Most people with idiopathic, or typical, PD develop symptoms at 50 years of age or older.

YOPD affects about four percent of the one million people with PD in the United States. Symptoms are similar to late onset PD but it is important to understand the challenges YOPD individuals often face at a financial, family and employment levels.

In rare instances, Parkinson's-like symptoms can appear in children and teenagers. This form of the disorder is called juvenile Parkinsonism and is often associated with specific, high-PD risk genetic mutations.
