Sleep Quality, Cognition, and Disease Severity in Parkinson's Disease - NCT07536490
Summary
The NIH National Library of Medicine registered an observational study (NCT07536490) on ClinicalTrials.gov investigating the relationship between sleep quality, cognitive function, and disease severity in individuals with Parkinson's disease. The single-session study will assess participants using standardized tools including the Stroop Test, Clock Drawing Test, Montreal Cognitive Assessment, Unified Parkinson's Disease Rating Scale, and Modified Hoehn and Yahr Scale. The study enrolls participants diagnosed with Parkinson Disease.
What changed
The NIH National Library of Medicine added a new observational study registration (NCT07536490) to ClinicalTrials.gov documenting a study examining whether sleep quality is associated with cognitive function and disease severity in individuals with Parkinson's disease. The study will conduct single evaluation sessions assessing sleep quality, cognitive function using the Stroop Test, Clock Drawing Test, and Montreal Cognitive Assessment, and disease severity using the Unified Parkinson's Disease Rating Scale and Modified Hoehn and Yahr Scale.
Healthcare providers, clinical researchers, and patients interested in Parkinson's disease research should note this registry entry for awareness of ongoing observational research in this therapeutic area. The study does not impose any compliance obligations but provides information about current clinical research on the relationship between sleep quality and neurological outcomes in Parkinson's disease.

Sleep Quality, Cognition, and Disease Severity in Parkinson's Disease
Observational NCT07536490 Kind: OBSERVATIONAL Apr 17, 2026
Abstract
The goal of this observational study is to investigate the relationship between sleep quality, cognitive functions, and disease severity in individuals with Parkinson's disease. The main question it aims to answer is:
Is sleep quality associated with cognitive function and disease severity in individuals with Parkinson's disease?
Participants will complete assessments of sleep quality, cognitive function, disease severity, and disease stage during a single evaluation session. Cognitive function will be evaluated using the Stroop Test, Clock Drawing Test, and Montreal Cognitive Assessment. Disease severity will be assessed using the Unified Parkinson's Disease Rating Scale, and disease stage will be determined using the Modified Hoehn and Yahr Scale.
