evaluation of consciousness impairment in severe tbi and full-cycle neuroregulation based on multimodal imaging

Conditions: Traumatic Brain Injury

Summary: the goal of this observational study is to learn about in evaluation of consciousness impairment in severe tbi and full-cycle neuroregulation based on multimodal imaging. the main question it aims to answer is: •for the existing examination means of super early neurological consciousness level recognition and function assessment accuracy of poor technical bottleneck, different period individual target brain space positioning difficulties and single rehabilitation technology of whole cycle rehabilitation system, with severe tbi patients as the research object.

brain trauma (traumatic brain injury, tbi) is one of the most common acute and severe diseases in neurosurgery. it has the characteristics of high disability rate and high mortality rate, and has become a major global medical and public health problem. disorder of consciousness (disorder of consciousness, doc) is one of the most common clinical manifestations in the early stage of severe tbi patients with coma. long-term doc is the main manifestation of poor prognosis and can cause disability or death. up to 43% of patients diagnosed with vegetative patients were reclassified as minimal consciousness. how to realize the accurate assessment of doc population consciousness state, strengthen the early identification and functional assessment of people with severe tbi, and establish the whole-process rehabilitation system and management strategy for severe neurological diseases are the main clinical concerns. this project for the existing examination means of super early neurological consciousness level recognition and function assessment accuracy of poor technical bottleneck, different period individual target brain space positioning difficulties and single rehabilitation technology of whole cycle rehabilitation system, with severe tbi patients as the research object. the specific research was mainly conducted from the following three aspects: (1) the relationship between eeg qualitative power spectrum typing, quantitative power spectrum index and behavioral scale, and the assessment of early awareness recovery in doc patients; (2) the auxiliary scheme for icu based on near-infrared light therapy; (3) the light-magnetic combined neuroregulation strategy for subacute patients based on precise positioning of fmri in the resting state.
