Clinical Trial Summary

This is a randomized placebo- and active-controlled trial for assessing the efficacy of bright light therapy for sleep and mood symptoms in patients with Parkinson's disease

Clinical Trial Description

The primary aim of this study is to compare the efficacy of timed-BLT (BLT group) in reducing excessive daytime sleepiness in patients with Parkinson's disease, when compared to a timed-inactivated negative ion generator (active-control group).

The secondary aims of the study are to examine the effect of timed-BLT on other non-motor symptoms, including depression, fatigue; and the quality of life.

Additional analyses will be carried out to examine the efficacy of the timed-placebo as compared to the random-time placebo (placebo group). ;
