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.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 30 to 75 with idiopathic Parkinson's disease experiencing motor fluctuations.

Not a fit: Patients with Parkinsonian syndromes other than idiopathic Parkinson's disease or those with significant cognitive impairment may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a validated tool for better assessing and managing neuropsychiatric symptoms in Parkinson's disease, ultimately improving patient care.

How similar studies have performed: Previous studies have shown promising results with similar assessment tools, indicating potential for success in this validation effort.
