title: Parkinson disease. Unravelling the nonmotor mysteries of Parkinson disease.
abstract: Parkinson disease (PD) is now regarded as a mixed motor, nonmotor and multiorgan disorder rather than a pure movement disorder. Nonmotor symptoms (NMS) have underpinned this conceptual change, and new criteria for clinical and prodromal diagnosis of PD, incorporating a range of NMS, have recently been published.
