The objective of this paper is to compare and contrast FMD and FS, and highlight important differences in etiology and the clinical approach towards these two entities. Patients with FMD often experience daily abnormal movements, while FS is characterized by paroxysmal events. Both patient populations share psychiatric and environmental comorbidities, but patients with FS may have increased anxiety and neuroticism and a higher percentage of childhood trauma. Functional MRI scans have demonstrated impaired executive control over motor behavior in both groups. FMD responds well to multidisciplinary rehabilitation-oriented treatment, while psychotherapy remains the mainstay of treatment for FS. For practicing clinicians, recognizing commonalities and differences in patients with FMD and FS is important to develop the most appropriate treatment plan.
