Parkinson's disease (PD) is a nervous system disorder that results in the degradation of motor skills in both men and women. PD, like other motor system diseases, is caused by the loss of dopamine-producing brain cells. Dopamine allows nerve cells to successfully transmit messages that control muscle movement. Devoid of the chemical, the brain scrambles commands, subsequently impairing muscular functions.
