Predicting whether and when these patients will recover consciousness remains one of the greatest challenges in neurocritical care. Current prognostic tools are limited, and inaccurate predictions may influence critical decisions regarding ongoing treatment and goals of care.\n\nPrevious work has demonstrated that cognitive motor dissociation (CMD) - brain activation detected by EEG in response to motor commands despite the absence of observable behavioral responses - is associated with long-term recovery. However, CMD testing has important limitations, including false-negative results in patients with aphasia, hearing impairment, language barriers, or fluctuating arousal.\n\nSleep architecture is profoundly disrupted after severe brain injury. Emerging evidence suggests that the presence of well-formed sleep spindles (WFSS) on EEG reflects preserved thalamocortical network integrity and is associated with recovery of consciousness and improved neurological outcomes. Sleep spindle detection offers a potentially scalable, inexpensive, and language-independent biomarker that can be obtained passively during routine EEG monitoring.\n\nThis study seeks to determine whether EEG sleep features, particularly WFSS, can improve prediction of early recovery of consciousness and long-term neurological outcomes while also developing novel EEG-based measures of functional network recovery.","Adult patients admitted to the ICU with acute neurological injury with Disorders of Consciousness (traumatic brain injury, and intracerebral hemorrhage) who demonstrate impaired consciousness and are unable to follow commands based on standardized clinical assessments (e.g., CRS-R).",[75],{"label":76,"type":68,"description":77,"interventionNames":68},"Intracerebral Hemorrhage and Traumatic Brain Injury","Adult patients with acute neurological injury with Disorders of Consciousness (traumatic brain injury, and intracerebral hemorrhage).",[79,84],{"name":80,"role":81,"phone":82,"phoneExt":68,"email":83},"Jan Claassen, MD","CONTACT","212-305-7236","jc1439@cumc.columbia.edu",{"name":85,"role":81,"phone":86,"phoneExt":68,"email":87},"Angela Velazquez, MD","212-305-6071","agv2113@cumc.columbia.edu",[89,109],{"facility":90,"status":68,"city":91,"state":92,"zip":93,"country":94,"countryCode":95,"cosmosGeoPoint":96,"geoPoint":101,"contacts":102},"University of Miami and Jackson Health System (UM\u002FJHS)","Miami","Florida","33136","United States","US",{"type":97,"coordinates":98},"Point",[99,100],-80.19366,25.77427,{"lat":100,"lon":99},[103,107],{"name":104,"role":81,"phone":105,"phoneExt":68,"email":106},"Ayham Alkhachroum, MD","305-243-6175","axa2610@med.miami.edu",{"name":104,"role":108,"phone":68,"phoneExt":68,"email":68},"PRINCIPAL_INVESTIGATOR",{"facility":110,"status":68,"city":111,"state":111,"zip":112,"country":94,"countryCode":95,"cosmosGeoPoint":113,"geoPoint":117,"contacts":118},"Columbia University Medical Center","New York","10032",{"type":97,"coordinates":114},[115,116],-74.00597,40.71427,{"lat":116,"lon":115},[119,120],{"name":80,"role":81,"phone":82,"phoneExt":68,"email":83},{"name":80,"role":108,"phone":68,"phoneExt":68,"email":68},{"type":108,"investigatorFullName":122,"investigatorTitle":123,"investigatorAffiliation":5,"oldNameTitle":68,"oldOrganization":68},"Jan Claassen","Professor of Neurology",[125,127],{"name":126,"class":6},"Miami University",{"name":128,"class":129},"National Institute of Neurological Disorders and Stroke (NINDS)","NIH","100653995","sleep-to-predict-recovery-in-unconscious-patients-with-acute-brain-injury-100653995",false,"NCT07794605","Sleep to Predict Recovery In Unconscious Patients With Acute Brain Injury","SPRINT","Inclusion Criteria:\n\n\\- Adults with non-penetrating traumatic brain injury (TBI) or with primary intracerebral hemorrhage (ICH) (i.e. from hypertension or anticoagulants) who remain behaviorally unresponsive to verbal commands (i.e., comatose vegetative state, or minimally conscious state minus \\[MCS-minus, defined as unresponsive with preserved visual fixation\u002Fpursuit or localization to noxious stimuli\\]) by day 2 after injury\n\nExclusion Criteria:\n\n* Evidence of consciousness within 2 days of injury\n* Uncontrolled seizures\n* pre-existing disorders of consciousness\n* deafness","ALL","18 Years",{"count":140,"type":141},230,"ESTIMATED","OBSERVATIONAL","Severe brain injuries can leave people in states where they are unconscious or only partly aware, such as a coma.
