Brief summary
The research focuses on establishing a system for detecting loss of consciousness, developing clinical prognostic and awakening-related brain function testing criteria.
Detailed description
A framework for the acquisition of neural features, feature selection and mechanism analysis of consciousness deficits in patients with acute and prolonged disorders of consciousness(DOC). Based on the multimodal data of three types of patients with DOC, the investigators established a comprehensive scientific collection of brain function features of acute and prolonged consciousness disorders; Revealed the key neural nodes and circuits of consciousness deficits, and elucidated the neural mechanisms of consciousness deficits in patients with prolonged consciousness disorders from EEG time-frequency-spatial features;

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from Coma recovery scale-revised | Within 24 hours of enrollment | CRS-R scale includes 6 dimensions such as audiovisual, arousal level, verbal response, motor and communication, scoring 0 to 23, the higher the score the better the neurological function, and each score reflects the presence or absence of the evaluated person and the strength of consciousness |
| Change from the p300 in electroencephalogram | Assessment within 24 hours before, and 1 hour after TMS treatment | Assessment the p300 in event related potential(ERP) |
| Change from resting-state in electroencephalogram | Assessment within 24 hours before, and 1 hour after TMS treatment | Assessment the spectral power and coherence by in resting-state EEG |
| Change from TEP in electroencephalogram | Assessment within 24 hours before, and 1 hour after TMS treatment | Assessment the TMS Evoked Potential(TEP) |
| Change from PCI in electroencephalogram | Assessment within 24 hours before, and 1 hour after TMS treatment | Assessment the perturbational complexity index(PCI) in TMS-EEG |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change from ROI in neuroimage techniques-PET | Assessment within 24 hours before ,and 1 hour after TMS treatment | The distribution of 18F-FDG in the brain was analyzed according to the imaging situation, and the brain regions of interest (ROI) were outlined, and the uptake of 18F-deoxyglucose (FDG) in the patients was observed according to the brain ROI. |
