Authors: K. Ray Chaudhuri, Anette Schrag, Daniel Weintraub, Alexandra Rizos, Carmen Rodriguez-Blazquez, Eugenia Mamikonyan and Pablo Martinez-Martin
The MDS-NMS is a revision of the Non-Motor Symptoms Scale (NMSS) and was developed to improve and refine the assessment of non-motor symptoms in Parkinson’s disease (PD). This rater-completed assessment measures frequency and severity of 13 non-motor domains, over 52 items and covers a range of key non-motor symptoms both PD and treatment related, and in greater depth, compared with the NMSS. The scale also has a new MDS-NMS Non-Motor Fluctuations (NMF) Subscale to assess changes in non-motor symptoms in relation to the timing of anti-parkinsonian medications across 8 domains.
This scale is expected to be useful in clinical care and research, including trials of investigational medicinal products related to PD. The MDS-NMS is a valid and reliable rating scale that measures the burden of non-motor symptoms, including non-motor fluctuations, in PD patients.
