Parkinson’s disease (PD) is a chronic, progressive, movement disorder of the brain that usually develops slowly over time that gives rise to unintentional or uncontrollable movements. It is classified as a movement (motor) disorder because it causes tremors, balance instability, slowness of movement and stiffening movements. But non-motor symptoms of PD such as depression, fatigue, anxiety, loss of taste and smell are serious concerns of people with PD.
