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 is the result of the loss of the brain chemical dopamine. When nerve cells, called neurons, in an area of the brain that controls movement become impaired and/or die, the amount of dopamine they normally produce decreases. This loss of dopamine causes the movement problems seen in people with PD.
