Who Is Affected by Parkinson's Disease
The number of new cases increases with age, affecting 1% of people older than 60 and up to 3% of people older than 85.3
Symptoms of Parkinson's disease most often first appear during a person's 50s or 60s. The disease progresses gradually over 10 to 15 years, resulting in increasing disability. Early-onset disease (before age 30 to 40) is not common. Among the total number of Parkinson's disease cases, 5% to 10% are early-onset.3
Parkinson's disease occurs more often in men than in women, but the reason for this is unknown.4
