Parkinson’s Disease refers to a chronic and progressive movement disorder due to which the neurons in the substantia nigra part of the brain are unable to carry out their normal functions. As the disease makes its progress, the amount of dopamine produced by some of those neurons reduces in quantity, affecting the patient’s ability to control the movement of his or her body. Bradykinesia, or slowness in movement, as well as a stiffness of the limbs, are common symptoms. Many patients also have problems with maintaining balance and coordination. They may also experience tremors in the face, jaw and hands. The onset of the disease is usually between the ages of 50 and 60. In some cases, the symptoms appear on one side of the body at first, and develop on the other side later.
