Hello. I am new to here and have an interest in critiques of Functional Neurological Disorder. I knew that three "positive" rule-in signs were tremor entrapments, Hoover's sign, and psychogenic seizures, but I also found a table that listed positive signs you will see in the table linked below...

Pathogenesis and pathophysiology of functional psychogenic movement disorders Baizabal-Carvallo; Hallett; Jankovic Functional movement disorders (FMDs), known over time as “hysteria”, and “dissociative”, “conversion”, “somatoform”, “non-organic” and “psychogenic” disorders, are characterized by...

The involuntary nature of conversion disorder V. Voon, C. Gallea, N. Hattori, MD, M. Bruno, V. Ekanayake, M. Hallett BACKGROUND What makes a movement feel voluntary, and what might make it feel involuntary? Motor conversion disorders are characterized by movement symptoms without a neurologic...

Abstract Objective: Neuroimaging studies have identified alterations in both brain structure and functional connectivity in patients with functional neurological disorder (FND). For many patients, FND emerges from physical precipitating events. Nevertheless, there are a limited number of case...
