Chinese FMDs Registry

The purpose of the Chinese Functional Movement Disorders Registry (FMDs-China) is to develop a database of patients with Functional Movement Disorders (FMDs) in China.

Functional movement disorders (FMDs), also known as psychogenic movement disorders (PMDs), formerly known as "hysteria or hysteria", is a representative functional nervous system disease. It has been reported in Europe and America that FMDs patients account for 3% - 6% of all patients in the outpatient department of motor disorders, but there is no relevant data report in China so far. From the current research, the incidence rate has gradually increased significantly. However, the research about the pathogenesis and diagnosis of such diseases is rare. These studies have the problem of small sample size and still lack large randomized controlled studies to demonstrate the long-term efficacy of different treatments. And in China, there are nearly no reliable research and the lack of basic understanding makes it a "gray area" for the diagnosis and treatment of FMDs. The purpose of this observational study is to prospectively register the information of patients with FMDs nationwide, establishing a Chinese multicenter FMDs China cohort; understanding the demographic characteristics, clinical characteristics and symptom characteristics, neuropsychological test, electrophysiological and imaging characteristics, drug use, etc. what's more, it lays a foundation for the research on the etiology and treatment in the second stage of this study.
