12 notable individuals who have been diagnosed with Parkinson’s Disease

Over one million Americans are living with Parkinson’s Disease (PD), with 60,000 new cases diagnosed each year. Many people do not realize that Parkinson’s is the second most common degenerative neurological disorder after Alzheimer’s disease. 

What is Parkinson’s Disease (PD)?

Parkinson’s Disease is a progressive nervous system disorder that affects the part of the brain responsible for movement. According to the Parkinson’s Foundation, PD primarily targets the neurons in the brain that produce dopamine – a chemical that sends signals throughout the brain affecting mood, movement, and memory. If you have Parkinson’s when these neurons die, they produce less dopamine, which causes the movement problems typically identified with PD.

Symptoms of PD are most likely to appear in individuals who are older than 60, however, symptoms can start at 50 or younger. In fact, about 10 percent of people with Parkinson’s may fall into this category. Actor Michael J. Fox was only 29 when he was diagnosed.

You may not realize it, but many notable individuals have been diagnosed with Parkinson’s Disease
