Purpose of the guideline: Functional movement disorders (FMDs), also known as psychogenic movement disorders (PMDs), are very representative functional neurological diseases, and the etiology and pathogenesis of FMDs are not yet clear. FMDs are characterized by various movement dysphylaxis symptoms, or symptoms inconsistent with known organic diseases. Most patients with FMDs have a history of mental illness such as stress, anxiety or depression, and some patients are even affected by stress for a long time. At present, FMDs account for 3-6% of movement disorder clinics, and there is no accurate epidemiological data in China. The age of FMDs onset is 35 to 50 years, and it is more common in women, but the actual incidence is wider. FMDs have now become an important subtype of movement disorders, but most clinicians (especially medical, neurologists, and psychiatrists) are poorly aware of the disease and are often helpless when dealing with such patients. The original version of Chinese expert consensus on the diagnosis and treatment of functional movement disorders was firstly developed in 2021 in China based on research and clinical experience from experts. Now, we are aiming the second version consensus with revisement and update based on original version.
