This study focuses on neuropsychiatric fluctuations (NPF) in Parkinson's disease. Due to the lack of specific assessment tools, we developed the Neuropsychological Fluctuations Scale (NFS), a 20-item questionnaire. Recent studies have confirmed its reliability, sensitivity, and validity. To finalize its validation, assessing its test-retest reliability is an essential next step.
