Cause of Parkinson's Disease: Loss or failure of dopamine-producing brain cells

Cause details for Parkinson's Disease: Parkinson's and related disorders are the result of the loss of dopamine-producing brain cells. Dopamine is a chemical messenger responsible for transmitting signals within the brain. Parkinson's disease occurs when certain nerve cells, or neurons, die or become impaired. Normally, these neurons produce dopamine. Loss of dopamine causes the nerve cells to fire out of control, leaving patients unable to direct or control their movement in a normal manner. 1
