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
The goal of this observational study is to learn about functional neurological disorders in patients with common non-functional movement disorders ("functional overlay"). The main questions it aims to answer are:
* What is the frequency of functional neurological disorders in patients with non-functional movement disorders (functional overlay)? * What are the characteristics of functional neurological disorders in patients with non-functional movement disorders?
Participants will be examined clinically and electrophysiologically, the examinations consist of:
* a neurological examination * neuropsychological testing * electrophysiological tremor diagnostic * questionnaires about psychological, biological and social risk factors
Researchers will compare patients with functional motor disorders to patients wit non-functional movement disorders to see if they differ from each other regarding the functional symptoms.
Inclusion: Functional or non-functional movement disorder; 18 to 80 years.
Exclusion: Patient is not able to consent; Patient is not able to understand / speak German fluently (questionnaires are available only in German).
