Study Summary
This study aims to determine the most effective dose of light therapy to improve sleep in people with Parkinson's Disease. Four groups of participants will receive bright-white or dim-red light therapy at different times throughout the day.
Primary Outcome
The PDSS-2 (Parkinson's Disease Sleep Scale 2) has a total score range from 0 to 60 points. Each item on the scale is scored on a scale of 0 to 4, with higher scores indicating more severe sleep problems. The PDSS-2 is a 15-question instrument designed to simultaneously capture the multidimensional aspects of sleep-related problems and changes in sleep quality.
