Only about 5% to 10% of everyone with Parkinson’s has the early-onset form of the disease.

Only about 2% of those diagnosed with Parkinson’s are under the age of 40.

A very few people are diagnosed with Parkinson’s before their 20th birthdays.

Researchers have identified several genes that are linked to Parkinson’s.

People with early-onset Parkinson’s disease are more likely to have genetic factors that caused their condition.

In addition, certain treatments includingexercise may be more likely to help younger people with Parkinson’s.
