In this study, high-resolution brain functional magnetic resonance imaging (MRI) was used to evaluate the differences in brain structure and brain function network between patients with different degrees of disturbance of cognition and healthy controls by means of cohort follow-up and control study. The changes of patients' The dynamic changes of learning, to explore its clinical value as an early diagnosis. Combined with neurobehavioral scales and high-resolution brain structure, functional magnetic resonance imaging data to assess the brain structure, functional characteristics and consciousness of patients with impaired consciousness, and initially establish awareness of patients with recovery of consciousness Predictable imaging signs. Twenty eligible controls, 20 VS patients, and 20 MCS patients will be considered for inclusion in the inclusion / exclusion criteria. Informed consent will be obtained as required before starting any registration process.
