What role does dopamine play in Parkinson's disease?

Dopamine is a brain chemical important for communication between cells, and it plays a major role in Parkinson's disease. In people with Parkinson's, the nerve cells that make dopamine begin to die off, and the amount of dopamine in the body is reduced as a result.

Treatment for Parkinson’s disease involves increasing the amount of dopamine in the brain. Because the system within the brain is so complex, however, correcting dopamine levels is difficult.
