Assessing a new questionnaire for neuropsychiatric fluctuations in Parkinson's disease

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the Neuropsychological Fluctuations Scale (NFS), a 20-item questionnaire designed to assess neuropsychiatric fluctuations in patients with Parkinson's disease. The research aims to establish the test-retest reliability of the NFS, which has shown promising psychometric properties in previous studies. Participants will complete the questionnaire and undergo a physical exam to ensure comprehensive evaluation. This validation step is crucial for confirming the NFS as a reliable tool for assessing non-motor symptoms in Parkinson's disease.
