Prevalence of nonmotor symptoms in Parkinson's disease in an international setting; Study using nonmotor symptoms questionnaire in 545 patients

TLDR

In 2006, no single instrument existed to comprehensively assess the wide range of nonmotor symptoms of Parkinson's disease. This study presents results from 545 Parkinson's disease patients using the definitive NMSQuest to highlight the prevalence of nonmotor symptoms. The PD nonmotor group, a multidisciplinary team including patient representatives, developed and validated the 30‑item NMSQuest, a self‑completed screening tool designed to draw attention to nonmotor symptoms. Results from 545 patients using the NMSQuest revealed a wide range of nonmotor symptoms in an international cohort. © 2007 Movement Disorder Society.

Abstract

Abstract 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. © 2007 Movement Disorder Society
