What is Parkinson disease?
Parkinson disease is a progressive neurological disorder that causes uncontrollable and unintentional movement. It can also be defined as a complex motor disorder that results from the degeneration of the nerve cells in the brain and then causing difficult movement of the body. It is a condition in which the brain deteriorates and affects muscle control, balance and movements. This medical condition also begins to affect the senses, mental health and thinking ability. This disease is mostly age related and more common in men. Many transmitters work together to aid body movement, but the most important of these neurotransmitters  is dopamine.
