What is Parkinson's Disease?

To put it simply, Parkinson's is a disease that affects the functioning of a small part of the brain.

Basically what happens is that certain nerve cells in that small part of the brain (the part called the "substantia nigra") start to degenerate and when they do a chemical in the brain called dopamine is lost.

Dopamine is a chemical that helps transmit signals or messages from the brain to different parts of the body.

Because the dopamine is reduced and the brain can't send the signals as well, this causes problems with body movement in someone with Parkinson's.

Unfortunately, the sad part about Parkinson's disease is that it is a disease that is long lasting and gets worse over time.

However, the good news is that because the disease progresses slowly, it usually takes years before there is a serious impact on a person's quality of life.
