The neurotransmitter dopamine regulates neurons in the SNpc that control muscular movement and coordination. As dopamine-producing cells die, dopamine levels fall, leading to uncontrolled muscle tremors and movements.1,2 Untreated, PD will progressively worsen and can eventually result in total disability. PD may lead to brain function deterioration and premature death.3
