Recovery of Consciousness Following Intracerebral Hemorrhage
Columbia University
Summary
The objectives of the RECONFIG clinical study are to : 1. To identify the time to the first diagnosis of cognitive motor dissociation (CMD) in intracerebral hemorrhage (ICH) patients and to investigate whether these patients will clinically follow commands earlier after the hemorrhage. 2. To determine whether CMD independently predicts long term functional outcomes (6-month mRS scores) in ICH patients, and is associated with long term cognitive and quality of life outcomes. 3. To determine the EEG response to verbal commands of the motor imagery paradigm between patients with and without sensory aphasia. The overall goal is to determine predictors and the trajectory of neurological recovery.
Description
Unconsciousness is common after an acute brain injury such as a brain hemorrhage, and recovery is poorly understood. This lack of knowledge is a key impediment to the development of novel strategies to improve outcomes and is one of the main reasons that prognostication of recovery of consciousness and functional outcomes is inaccurate. One-fifth of clinically unconscious patients with acute brain injury are able to follow commands using a simple, bedside EEG motor imagery test that directly measures brain activity associated with the attempt to move. This state is called cognitive motor disso…

Inclusion Criteria: * 18 years or older. * Diagnosis of primary ICH (i.e., related to hypertension or anticoagulants) on Head CT and/or MRI in the frontal lobe, thalamus, or striatocapsular region. * Unresponsive to commands within 48 hours after onset of the bleed. * English, Spanish or, French as the primary language. Exclusion Criteria: * Major bleeding in the cortex outside of the frontal lobe, cerebellum, or brainstem (judged as a cause for unconsciousness as per the attending neurointensivist). * Other causes of ICH or different types of acute brain injury (e.g., traumatic brain injur…
