Summary

The purpose of this study is to investigate the genetic variants of clock and narcolepsy genes that determine the therapeutic effects of Stalevo® on the quality of sleep in patients with Parkinson's Disease.

Clinical Details

Official title: Clock and Narcolepsy Genetic Variants and the Effects of Stalevo® (Levodopa/Carbidopa/Entacapone) on Sleep Disorders in Parkinson's Disease

Study design: Endpoint Classification: Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: The correlation of the genetic variants of central circadian clock and narcolepsy genes with regard to the treatment effect of Stalevo® in sleep disturbance of parkinson's disease.

Secondary outcome:

The effectiveness of Stalevo® in bedtime on the quality of sleep in PD patients with motor fluctuation (using Parkinson's Disease Sleep Scale)

The effectiveness about improving the EDS(Excessive daytime sleepiness) in PD patients with motor fluctuation after taking Stalevo® in bedtime.

The effectiveness about improving the morning motor symptoms in PD patients with motor fluctuation after taking Stalevo® in bedtime.
