What this trial studies

This project aims to validate two new rating scales, the Neuropsychiatric Fluctuations Scale (NFS) and the Shame in PARKinson's disease (SPARK) Scale, to better understand non-motor symptoms in Parkinson's Disease (PD). It is a prospective international multicentre study involving at least 300 PD patients across several countries including Spain, Germany, France, Switzerland, Romania, and Greece. The NFS focuses on detecting neuropsychiatric fluctuations in patients, while the SPARK Scale addresses issues of shame and embarrassment related to PD. The validation of these scales is expected to enhance the management of PD by providing more accurate assessments of these symptoms.

Why it matters

Potential benefit: If successful, this study could lead to improved recognition and management of non-motor symptoms in Parkinson's Disease, enhancing patient care.

How similar studies have gone: Other studies have shown success in validating scales for non-motor symptoms in various conditions, but the specific scales being validated in this study are novel for Parkinson's Disease.
