Effects of Bright Light Treatment on Daytime Sleepiness and Nocturnal Sleep in Patients With Parkinson's Disease
Study objectives are to determine the efficacy, safety and tolerability of bright light
treatment in Parkinson's Disease (PD) patients with daytime sleepiness. Thirty PD patients
will be enrolled and equally randomized to bright light or dim-red light treatment.
Objective (actigraphy) and subjective (sleep logs/scales) sleep measures will be collected
through the baseline and intervention phases of the study. The primary outcome measure will
be the change in the Epworth Sleepiness Scale (ESS) comparing the bright light treatment
with dim-red light treatment. Secondary outcome measures will include the Multiple Sleep
Latency Test (MSLT), global Pittsburgh Sleep Quality Index (PSQI) score, Parkinson's Disease
Sleep Scale (PDSS) score, and actigraphy measures. A variety of exploratory analyses will
examine the effects of bright light treatment on fatigue, depression, quality of life,
cognition, and motor disability.
Hypothesis: Bright light exposure will diminish daytime sleepiness and improve night-time
sleep in PD patients with daytime sleepiness.
