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 results from the loss of brain cells in a region of the brain that controls movement. This loss creates a shortage of dopamine, which is a chemical in the brain called a neurotransmitter.This loss of dopamine results in the problems with movement that are characteristic of Parkinson's disease.his loss causes a deficiency of a certain brain chemical (dopamine), which causes movement problems. Parkinson's disease is a common condition of the brain that typically begins in the middle to later part of life. It is a progressive condition, meaning that it continues to get worse with time.
