Micro-expressions in Patients With Prolonged Disorders of Consciousness

Recruiting now

Conditions studied: Consciousness Disorders

In brief

The goal of this observational study is to learn about the microexpressions in patients with prolonged disorders of consciousness. The main questions it aims to answer are: * Inducing micro-expression changes in patients with prolonged disorders of consciousness through various emotional stimuli, and further to achieve precise classification of their levels of consciousness. * Detecting micro-expressions in patients with prolonged disorders of consciousness to assist clinical diagnosis of levels of consciousness, e.g., complement the disgnosis of clinical scales such as CRS-r scale. * By monitoring micro-expression changes in patients with prolonged disorders of consciousness, researchers can explore their residual brain function, thereby advancing research into relevant neural mechanisms. Participants will be subjected to consciousness assessment by CRS-r scale, and their micro-expression changes in response to various emotional stimuli will be captured, along with the collection of EEG and MRI data. Follow-up evaluations will be conducted using the CRS-R scale and GOS scale, with a follow-up period of 6 months.
