Clinical Trial Summary

The research focuses on establishing a system for detecting loss of consciousness, developing clinical prognostic and awakening-related brain function testing criteria.

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;

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from Coma recovery scale-revised	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	Within 24 hours of enrollment
Primary	Change from the p300 in electroencephalogram	Assessment the p300 in event related potential(ERP)	Assessment within 24 hours before, and 1 hour after TMS treatment
Primary	Change from resting-state in electroencephalogram	Assessment the spectral power and coherence by in resting-state EEG	Assessment within 24 hours before, and 1 hour after TMS treatment
Primary	Change from TEP in electroencephalogram	Assessment the TMS Evoked Potential(TEP)	Assessment within 24 hours before, and 1 hour after TMS treatment
Primary	Change from PCI in electroencephalogram	Assessment the perturbational complexity index(PCI) in TMS-EEG	Assessment within 24 hours before, and 1 hour after TMS treatment
Secondary	Change from ROI in neuroimage techniques-PET	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.	Assessment within 24 hours before ,and 1 hour after TMS treatment
