Parkinson’s disease is a progressive degenerative disorder of the brain due to the loss of dopamine-producing cells in the basal ganglion region of the brain. The four primary symptoms of Parkinson’s are tremor or trembling in hands, arms, legs, jaw, and face, rigidity or stiffness of the limbs and trunk, bradykinesia, or slowness of movement; and postural instability or impaired balance and coordination. Medications provide dramatic relief from the symptoms, but no drug can stop the progression of the disease. In some cases, surgery (Deep brain stimulation) is an appropriate treatment.
