- NA
- Status
- RECRUITING
- Sponsor
- Second Affiliated Hospital of Soochow University
- Study Type
- INTERVENTIONAL
- Enrollment
- 50 participants

Plain-Language Summary
The trial is testing whether daily light therapy can improve sleep and circadian rhythm problems in people with moderate Parkinson's, with the goal of improving nighttime sleep, daytime alertness, and overall function. Participants use either a bright light box or a dim light box as a control, with light exposure stimulating the retina to reset the brain's circadian clock and boost wakefulness; it does not directly change how levodopa works, and everyone keeps their Parkinson's medications stable during the study. They are looking for people aged 50 to 80 with Parkinson's at Hoehn and Yahr stages 2 to 3 who have had stable Parkinson's meds for at least one month and agree not to change them. People with major visual problems, significant cognitive impairment (MMSE under 24), uncontrolled psychiatric symptoms, current use of hypnotics or stimulants, or major circadian disruptions like shift work or recent jet lag are excluded; antidepressants are allowed only if the dose has been stable for more than three months.
