Parkinson's disease is a movement disorder of the nervous system that worsens over time. The nervous system is a network of nerve cells that controls many parts of the body, including movement. Parkinson’s disease is a degenerative brain condition that affects muscle control, movement and other functions. Learn about the symptoms, causes, diagnosis and treatment options for this common age-related disorder. PD develops when certain nerve cells (neurons) in the brain die. These are neurons that produce a chemical called dopamine. Dopamine helps relay messages between areas of the brain that control body movement. When these neurons die, abnormally low levels of dopamine are produced. Learn about Parkinson's Disease, its common symptoms, potential causes, the latest treatments, and how to live a full life with the disease.
