Observational study on functional neurological disorders in movement disorder patients
Official title: Prevalence and Clinical Presentation of Functional Neurological Disorders in Patients With Movement Disorders - A Cross-sectional Study in the Movement Disorders Clinic of the Department of Neurology, Medical University of Graz
Run by Medical University of Graz · NCT05943652 · Data updated 2026-11-12
This study looks at how common functional neurological disorders are in patients with movement disorders to see how they differ from those with non-functional movement issues.

What this trial studies
This observational study aims to investigate the prevalence and characteristics of functional neurological disorders (FND) in patients with non-functional movement disorders, referred to as 'functional overlay'. Participants will undergo a series of clinical and electrophysiological examinations, including neurological assessments, neuropsychological testing, and questionnaires that evaluate psychological, biological, and social risk factors. The study seeks to compare patients with functional motor disorders to those with non-functional movement disorders to identify differences in functional symptoms and underlying mechanisms.
Why it matters
Potential benefit: If successful, this study could enhance understanding of functional neurological disorders, leading to better diagnosis and treatment strategies for affected patients.
How similar studies have gone: While functional neurological disorders are a recognized area of study, this specific observational approach to understanding their prevalence in movement disorders is relatively novel.
