Plain-language summary

Parkinson's disease (PD) is a progressive disease that usually affects the motor system but is also associated with a non-motor symptom (NMS) complex that ranges from dribbling saliva, constipation, depression, sleep disorders, apathy, hallucinations, and dementia. These features contribute significantly to morbidity and institutionalization, more than quadrupling the cost of care. Furthermore, recent evidence suggests that NMS such as constipation, olfaction, rapid eye movement behavior disorder, fatigue, and depression may be markers of a preclinical stage of PD. PD-NMS are not well recognized in clinical practice and part of the reason is the lack of any instrument that aims to assess the complex range of NMS of PD in a unified and integrated manner. Recently, an international, multidisciplinary PD-NMS group has developed an integrated questionnaire and scale to assess NMS of PD in a comprehensive manner. This will help improve care and treatment of PD in the future.

How to read this study

Design: this is a narrative review. It summarises a field without a fixed search method, so it shows how authors read the evidence rather than measuring it. Use it to find the primary studies, not as a result in itself.
Size: the record gives no participant count. Look for one in the original before trusting a pattern.
Effect: the record gives no effect size, so the summary above cannot say how large any difference was.

What the evidence grade means here

This page is graded low. alzhub.org assigns the grade automatically from keywords in the abstract, not from reading the paper. Low means the abstract matched neither pattern. It is the default label, and it does not mean the work is poor; many sound lab and imaging papers land here. It can add at most 5 of the 100 points in the study score, and it is a label about design, not a verdict on whether the findings are true.

How this study scored 36/100

Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomized / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multicenter collaboration, so those were left out: it earned 21 of the 58 points we could judge it on, which is 36 out of 100.
