Advances on neuroimaging of functional movement disorder

Functional movement disorder (FMD) is a common type of conversion/dissociative disorder. In recent years, the continuous development of imaging techniques such as fMRI, DTI and PET, as well as analytical methods such as morphological analysis and fiber tract tracking, not only provides technical support for the study of neurobiological mechanisms of FMD, but also has important value for its differential diagnosis, efficacy evaluation and prognosis prediction. This article reviews the progress of imaging research on FMD, so as to provide basis for diagnosis, treatment and pathophysiological mechanism of the disease.
