Abstract:

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.

摘要：

功能性运动障碍是临床常见的转换性/分离性障碍。fMRI、扩散张量成像、PET等成像技术以及形态学分析、纤维束追踪等分析方法的不断发展不仅为功能性运动障碍神经生物学机制研究提供技术支持，而且对其鉴别诊断、疗效评价和预后预测具有更重要价值。本文综述功能性运动障碍影像学研究进展，以为疾病诊断与治疗、病理生理学机制探究提供依据。
