Outcome Measures

Primary Outcomes (1)

  • Evaluate the variation of the scale of the behavioral evaluation

    show that a 10-week treatment with N-acetylcysteine compared to placebo improves the mild-to-moderate impulse control disorders induced by dopaminergic medications in Parkinson's disease. The primary endpoint is the change in score from Part IV of the Ardouin Parkinson's Behavioral Assessment of Parkinson's Disease (ECMP) (ECMP IV), which evaluates hyperdopaminergic behaviors between the baseline and after 10 weeks. treatment.
