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 develops as a result of the death of dopamine-producing nerve cells in the brain.
