NCT05483036Completed
Perception in Parkinson's Disease
Source: ClinicalTrials.gov · Last updated 19 Sept 2025
Brief summary (registry, in English)
The investigators plan to examine the relation of perceptual variables-basic vision, unusual perceptual experiences(including but not limited to visual hallucinations)-to relevant functional variables such as cognition, mood, and alertness/sleepiness in an online sample of persons with Parkinson's disease (PwPD). It is hypothesized that unusual perceptual experiences will relate significantly to the selected variables. Participants do not need to experience visual hallucinations to be able to participate in this study. This is an observational study only, and not an interventional study.
