Abstract:
Psychogenic movement disorders (PMDs) can present with varied phenomenology that may resemble organic movement disorders. The diagnosis is based on clinical evaluation with a supporting history and classic features on neurologic examination. Ancillary testing, such as imaging and neurophysiologic studies, can provide supplementary information but is not necessary for diagnosis. There is no standard protocol for the treatment of PMDs, but a multidisciplinary approach has been recommended. This review discusses the clinical characteristics of various PMDs as well as ancillary testing, treatment, and research in the pathophysiology of this complex group of disorders.
