What is parkinsons diseases? Parkinsonâs occurs when certain nerve cells (neurons) in a part of the brain called the substantia nigra die or become impaired. Normally, these cells produce a vital chemicâ¦al known as dopamine. Dopamine allows smooth, coordinated function of the body's muscles and movement.
Parkinson's Disease. Parkinson's disease is a chronic, progressive disease that develops when the cells that produce dopamine are dead or severely damaged. Dopamine acts as a neurotransmitter in the brain and helps control behavior, cognition, motor activity and several other actions.hen these cells do not function properly, the brain often loses control of some bodily actions. Parkinson's disease often begins as a tremor in the hand that slowly spreads throughout the body, causing slowed voluntary motion, rigid muscles, stooped posture, loss of involuntary movements and speech changes.
