Sleep Quality, Cognition, and Disease Severity in Parkinson's Disease

Brief summary (registry, in English)

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.
