Primary Outcome Measures:
  • Change in participant's motor symptoms [ Time Frame: Baseline, Day 1, Month 3, Month 6, and every 6 months thereafter ]

  • Change in the non-motor symptoms. [ Time Frame: Baseline, Day 1, Month 3, and very 6 months thereafter ]
    Evaluated via the Non-Motor symptoms Scale (NMS) and the Parkinson's Disease Sleep Scale (PDSS-2).

  • Change in the participant's Healthcare Resource Utilization [ Time Frame: Baseline, Month 3, and every 6 months thereafter ]
    Evaluated via the Health Care Resources Utilization Questionnaire (HCRU).

  • Change in the Parkinson's Disease Questionnaire (PDQ-39) [ Time Frame: Baseline, Day 1, Month 3, and every 6 months thereafter ]
    Evaluated via the Parkinson's Disease Questionnaire (PDQ-39)

  • Change in caregiver work productivity [ Time Frame: Baseline, Day 1, Month 3, and every 6 months thereafter ]
    Evaluated by the Work Productivity and Activity Information Questionnaire (WPAI - care giver)

  • Change in caregiver burden [ Time Frame: Baseline, Day 1 , Month 3, and every 6 months thereafter ]
    Evaluated via the Zarit Care Giver Burden Questionnaire.
