About the trial

What the trial wants to find out

The goal of this project is to develop the international validation of two new rating scales, the Neuropsychiatric Fluctuations Scale (NFS) and the Shame in PARKinson's disease (SPARK) Scale, in order to improve the understanding of the extent and severity of non-motor symptoms in Parkinson's disease (PD).

The 2 groups in the trial

  • Patients with neuropsychiatric fluctuations

    PD patients with neuropsychiatric fluctuations (≥ 2 positive answers in QUICK test)

  • Patients without neuropsychiatric fluctuations

    PD patients without neuropsychiatric fluctuations (≤ 1 positive answer in QUICK test)

Questions to ask the study team

  1. How often do I need to come in, and for how long each time?
  2. Are travel costs paid?
  3. Can I keep my own doctor?
  4. What happens if I want to stop?
