Brief Summary:
The purpose of this study is to see whether the ICDs(Impulse Control Disorder) are improved and neuropsychiatric traits related to ICD are changed or not when switching dopamine agonist to levodopa/carbidopa in patients with Parkinson's disease who have been treated with dopaminergic medications.

Condition or disease Intervention/treatment Phase
Impulse Control Disorder Drug: Levodopa/Carbidopa(200mg/50mg) Drug: Dopaminergic Agonists Phase 4

Detailed Description:
  • PRIMARY OBJECTIVE To evaluate the improvement of mMIDI(modified version of Minnesota Impulsive Disorders Interview,Korean version) score from the baseline to 12 weeks or LOCF(Last Observation Carried Forward)
  • SECONDARY OBJECTIVE i) To evaluate the improvement of neuropsychiatric profiles from the baseline to 12 weeks or LOCF ii) To evaluate the improvement of UPDRS(Unified Parkinson's Disease Rating Scale)Score from the baseline to 12 weeks or LOCF

Arm Intervention/treatment
Experimental: Levodopa/Carbidopa(200mg/50mg) Drug: Levodopa/Carbidopa(200mg/50mg)
Experimental: Control A (dopaminergic agonist )
Parkinson patients treated with anti-Parkinson drug over 6 months.
Drug: Dopaminergic Agonists
Treated for at least 6 months after diagnosis of Parkinson's Disease.

No Intervention: Control B (no drug)
Parkinson diseased patients not treated.

Primary Outcome Measures :
  1. mMIDI(modified Minnesota Impulsive Disorders Interview) [ Time Frame: 12weeks ]
    To evaluate the improvement of mMIDI(Korean version) score from the baseline to 12 weeks or LOCF(Last Observation Carried Forward)

Secondary Outcome Measures :
  1. Neuropsychiatric profile [ Time Frame: 12 weeks ]

    To evaluate the improvement of neuropsychiatric profiles from the baseline to 12 weeks or LOCF

    * Neuropsychological assessment

    • General cognitive status: K-Minimental status exam(K-MMSE)
    • Psychiatric profile:

      • Neuropsychiatric inventory (K-NPI)
      • Beck depression inventory (BDI)
      • Barratt impulsiveness scale (BIS)
      • Beck anxiety inventory (BAI)
      • State-trait anger expression inventory (STAXI)
      • Obsessive compulsive inventory (OCI)
    • Evaluation of global change:

      • Patient global impression of improvement (PGI-I)
      • Clinical global impression of improvement (CGI-I)
