Outcome Measures

Primary Outcomes (2)

  • Change from baseline to 4-week f/u in Movement Disorder Society Unified Parkinson's Disease Rating Scale Part III score

    Movement Disorder Society Unified Parkinson's Disease Rating Scale Part III score will be used to determine the efficacy of amantadine. Higher scores mean a worse outcome. \[minimum 0, maximum 132\]

    Baseline, 4 weeks

  • Change from baseline to 8-week f/u in Movement Disorder Society Unified Parkinson's Disease Rating Scale Part III score

    Movement Disorder Society Unified Parkinson's Disease Rating Scale Part III score will be used to determine the efficacy of amantadine. Higher scores mean a worse outcome. \[minimum 0, maximum 132\]

    Baseline, 8 weeks

Secondary Outcomes (14)

  • Change from baseline to 4-week f/u in Movement Disorder Society Unified Parkinson's Disease Rating Scale Part I score

    Baseline, 4 weeks

  • Change from baseline to 8-week f/u in Movement Disorder Society Unified Parkinson's Disease Rating Scale Part I score

    Baseline, 8 weeks

  • Change from baseline to 4-week f/u in Movement Disorder Society Unified Parkinson's Disease Rating Scale Part II score

    Baseline, 4 weeks

  • Change from baseline to 8-week f/u in Movement Disorder Society Unified Parkinson's Disease Rating Scale Part II score

    Baseline, 8 weeks

  • Change from baseline to 4-week f/u in Movement Disorder Society Unified Parkinson's Disease Rating Scale Part IV score

    Baseline, 4 weeks

  • +9 more secondary outcomes

Study Arms (1)

PD patients who have taken amantadine

EXPERIMENTAL
Drug: Determination of drug effects through amantadine cessation

Interventions

Patients will discontinue amantadine, which has been taken since beginning of diagnosis.

PD patients who have taken amantadine
