Parkinson's Disease is the most common of a group of disorders that are the result of the loss of dopamine producing brain cells. One million people in the U.S. have Parkinson's Disease. There are four primary symptoms: tremors in the extremities, face and jaw; rigidity of the limbs and trunk; slowness of movement; impaired balance and coordination. Difficulty walking, talking or completing other simple tasks increases as the symptoms increase. Parkinson's disease is a chronic and progressive disease. No cause has been found. It is not inherited, nor is it contagious.
