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.
