Parkinson's disease is a progressive neurological disorder. It affects brain cells that produce a chemical called "Dopamine," which is responsible for smooth and coordinated body movements. As a result, this condition is also known as a "Movement Disorder." Although there is no known cause for this disease, its gradual progression reduces one's ability to move around with ease over time. What causes Parkinson's Disease? Parkinson's disease develops when the neurons that control movement in the brain are damaged or die. Parkinson's disease causes brain neurons to produce dopamine, a brain chemical that regulates movement, mood, and many other bodily functions. Parkinson's disease also affects nerve endings involved in the production of norepinephrine, a brain chemical that regulates automatic functions in the body such as blood pressure, digestion, and heart rate.
