Parkinson’s disease is a progressive neurodegenerative disorder that affects the motor system of the central nervous system. When certain nerve cells within the brain degenerate, they can no longer send sufficient dopamine throughout the brain which in turn leads to motor control issues ranging from dyskinesia (uncontrolled movements) to brady kinesia (frozen movements or inability to consciously move). Other symptoms may arise as well: tremors (in the arms, hands, or legs), stiff muscles, slow movement, problems with balance and walking, dementia and confusion, depression and general cognitive decline.
