Mov Disord. 2007 Aug 15;22(11):1623-9. doi: 10.1002/mds.21586.


2006, there was, no single instrument (questionnaire or scale) for attempting a comprehensive assessment of the wide range of nonmotor symptoms (NMS) of Parkinson's disease (PD). The PD nonmotor group, a multidisciplinary group of experts including patient group representatives developed and validated the NMS screening questionnaire (NMSQuest) comprising 30 items. The NMSQuest is a self completed screening tool designed to draw attention to the presence of NMS. In this paper, we present the results gathered from 545 patients using the definitive version of the NMSQuest highlighting the prevalence of the wide range of NMS flagged in the NMSQuest from consecutive PD patients in an international setting.
