Study of Brain Function Evaluation and Intervention System for Acute and Prolonged Disorders of Consciousness

Not Applicable
Conditions
Disorder of Consciousness
Interventions
Device: Transcranial magnetic stimulation
Device: Sham Transcranial magnetic stimulation
Registration Number
NCT05682248
Lead Sponsor
Xuanwu Hospital, Beijing
Brief Summary

The research focuses on establishing a system for validating the effectiveness of key technologies for targeted combined non-invasive interventions in awakening consciousness.

Detailed Description

Analyzed the EEG activity and brain network changes before and after stimulation by TMS stimulation of key brain regions, and correlated them with brain function. To verify the "time-frequency-space" neural mechanism of consciousness.

Primary Outcome Measures
NameTimeMethod
Change from resting-state in electroencephalogramAssessment within 24 hours before, and 1 hour after TMS treatment

Assessment the spectral power and coherence by in resting-state EEG

Change from PCI in electroencephalogramAssessment within 24 hours before, and 1 hour after TMS treatment

Assessment the perturbational complexity index(PCI) in TMS-EEG

Change from Coma recovery scale-revised(CRS-R)Assessment within 24 hours before, and 1 hour after TMS treatment

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 TEP in electroencephalogramAssessment within 24 hours before, and 1 hour after TMS treatment

Assessment the TMS Evoked Potential(TEP)

Change from the p300 in electroencephalogramAssessment within 24 hours before, and 1 hour after TMS treatment

Assessment the p300 in event related potential(ERP)

Change from ROI in neuroimage techniques-PETAssessment 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.
