Arm Intervention/treatment
Experimental: Stalevo®
Participants who are assigned to Stalevo Arm will take Stalevo® at bedtime for 3 month.
Drug: Stalevo®
  • Sleep disorders in Parkinson's disease
  • Analysis by Parkinson's Disease Sleep Scale(PDSS) scores.
  • If the PDSS score is improving at least 15 percent than the baseline score, It can be determined to be effective.
Other Name: Levodopa/Carbidopa/Entacapone




Primary Outcome Measures :
  1. 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. [ Time Frame: 2 years ]
    To determine whether the genetic variants of clock and narcolepsy genes are associated with the effectiveness of Stalevo® in bedtime on the quality of sleep in PD patients with motor fluctuation.


Secondary Outcome Measures :
  1. The effectiveness of Stalevo® in bedtime on the quality of sleep in PD patients with motor fluctuation (using Parkinson's Disease Sleep Scale) [ Time Frame: up to 3 months from enrollment. ]
    To determine whether Stalevo® in bedtime improves the quality of sleep in PD patients with motor fluctuation using Parkinson's Disease Sleep Scale.

  2. The effectiveness about improving the EDS(Excessive daytime sleepiness) in PD patients with motor fluctuation after taking Stalevo® in bedtime. [ Time Frame: up to 3 months from enrollment. ]
    Excessive daytime sleepiness (EDS) is characterized by persistent sleepiness and often a general lack of energy, even after apparently adequate or even prolonged night time sleep. EDS can be considered as one of features of sleep disturbance in parkinson's disease. It will be assessed using a composite measurement consisting of Unified Parkinson's Disease Rating Scale (UPDRS), Hoehn and Yahr stage, Parkinson's Disease Sleep Scale (PDSS), Epworth Sleepiness Scale (ESS), Parkinson's Disease Wearing Off Questionnaire-9 (PDWOQ-9), and Parkinson's Disease Quality of Life Questionnaire-39 (PDQ-39).

  3. The effectiveness about improving the morning motor symptoms in PD patients with motor fluctuation after taking Stalevo® in bedtime. [ Time Frame: up to 3 months from enrollment ]
    To determine whether Stalevo® in bedtime improves the morning motor symptoms in PD patients with motor fluctuation. It will be assessed using a composite measurement consisting of Unified Parkinson's Disease Rating Scale (UPDRS), Hoehn and Yahr stage, Parkinson's Disease Sleep Scale (PDSS), Epworth Sleepiness Scale (ESS), Parkinson's Disease Wearing Off Questionnaire-9 (PDWOQ-9), and Parkinson's Disease Quality of Life Questionnaire-39 (PDQ-39).
