The main questions this study aims to answer are:\n\nHow do functional MRI findings (e.g., covert consciousness and network connectivity) associate with current level of consciousness? How do functional MRI findings (e.g., covert consciousness and network connectivity) associate with future recovery of consciousness? How does noxious stimulation affect the detection of covert consciousness and functional brain network connectivity?","Patients with disorders of consciousness (lacking overt signs of consciousness such as command-following) due to acute brain injury will be identified and enrolled via the Recovery of Consciousness Via Evidence-Based Medicine and Research (RECOVER) Program. Patients in the study will undergo a detailed behavioral consciousness assessment (with the Coma Recovery Scale - Revised \\[CRS-R\\]), conducted by specially trained personnel, as well as a task-based functional MRI with auditory stimulation (motor commands) to assess for technologic covert consciousness (the willful modulation of brain activity to command) and functional brain network connectivity. For a subset of patients, the functional MRI will be performed with and without noxious stimulation, during the same scanning session. Patients will undergo repeat behavioral evaluations at hospital discharge, and 3 and 6 months after, to assess for overt consciousness recovery.",[18,19,20,21,22],"Disorder of Consciousness","Comatose","Coma; Prolonged","Vegetative State","Minimally Conscious State",[],"INTERVENTIONAL","DIAGNOSTIC",[27],"NA",{"count":29,"type":30},150,"ESTIMATED",[32],{"type":33,"name":34,"description":35,"armGroupLabels":36},"DIAGNOSTIC_TEST","Functional MRI (fMRI)","Research MRI, which will include both structural and functional sequences, will either be collected independently, or in conjunction with clinically-indicated sequences.
