Clinical Trial Summary

By collecting multimodal metrics (e.g., clinical factors, neuroimaging, and EEG) in the early phase of severe brain injury (i.e., during the acute hospitalization when a patient has impaired consciousness), and measuring the patients' recovery of consciousness, function, and quality of life in the late phase (at 6 months following the brain injury), we aim to construct an algorithm that synthesizes the results of these metrics to help predict recovery.


Description:

The primary aim of this research proposal is as follows: By collecting multimodal metrics (e.g., clinical factors, neuroimaging, and EEG) in the early phase of severe brain injury (i.e., during the acute hospitalization when a patient has impaired consciousness), and measuring the patients' recovery of consciousness, function, and quality of life in the late phase (at 3, 6, and 12 months following the brain injury), we aim to construct an algorithm that synthesizes the results of these metrics to help predict recovery. There will also be secondary aims as follows: 1. To identify patient phenotypes with predictive significance, in order to revise our classification scheme for disorders of consciousness in a clinically meaningful and data driven manner. 2. To compare prognostic value between metrics. 3. To determine how the initial goals of care expressed in the acute setting (i.e., the expected quality of life associated with disability) compare to the actual quality of life in the chronic setting (i.e., the actual quality of life associated with disability). 4. To compare the prognostic value of metrics between different etiologies of brain injury.

Accepts healthy volunteers No
Gender All
Age group 18 Years and older
Eligibility Inclusion Criteria: - Acute brain injury (including ischemic stroke, intracranial hemorrhage, anoxic brain injury, traumatic brain injury, encephalitis) - Inability to follow commands, speak intelligibly, or communicate (i.e., diagnosis of coma, vegetative state, or minimally conscious state minus) due to the underlying brain injury and within 28 days of the brain injury - Age 18 or greater. Exclusion Criteria: - Subjects will be excluded if they do not speak English (given the reliance on verbal questionnaires conducted in English) or if they regain the ability to follow commands, speak intelligibly or communicate (i.e., improves to minimally conscious state plus or greater) before they undergo MRI or EEG.

Intervention

Diagnostic Test:
MRI
MRI will include structural sequences (e.g., T1 weighted imaging, T2 weighted imaging, T2 FLAIR, diffusion weighted imaging with apparent diffusion coefficient, susceptibility weighted imaging, and diffusion tensor imaging). Using the structural sequences we will make note of the types of brain lesions (e.g., ischemic stroke, hemorrhage, hypoxic-ischemic brain injury), and the locations of these brain lesions. MRI will also include fMRI under three conditions: while the patient is at rest (to evaluate resting state functional connectivity), while the patient is exposed to auditory stimuli (to evaluate passive fMRI responses to stimuli), and while the patient is asked to follow commands (to evaluate active fMRI responses to tasks).
EEG
The EEG will include resting, stimulus-based, and task-based assessments of brain function.

Outcome

Type Measure Description Time frame Safety issue
Primary Glasgow Outcome Scale-Extended Metric of neurologic function. The minimum score is 1, and the maximum score is 8. Higher scores represent less disability (8 represents non-disabling symptoms, 1 represents death). 6 months following enrollment
