The primary aims of this study are:

1. To determine the feasibility of deploying mindBEAGLE, a portable, bedside EEG-based system, in the Intensive Care Unit in patients with disorders of consciousness (DOC) or locked-in syndrome (LIS);
2. To determine if mindBEAGLE neurophysiologic markers of cognitive function correlate with bedside behavioral assessments of consciousness;
3. To determine if mindBEAGLE neurophysiologic markers of cognitive function correlate with functional MRI (fMRI) and electroencephalography (EEG) biomarkers of consciousness;
4. To determine if mindBEAGLE can serve as an assistive communication device for people with LIS.

Inclusion Criteria:

• Age>18
• Diagnosis of coma
• Vegetative state
• Minimally conscious state
• Confusional state
• Locked-in state

Exclusion Criteria:

• History of developmental, neurologic, or major psychiatric disorder resulting in functional disability

During mindBEAGLE assessment in the intensive care unit, which lasted up to 4 hours.

Participants with Disorders of Consciousness or Locked in Syndrome were enrolled in the Neuro-ICU where adverse events, related or unrelated to the intervention/device were systematically monitored through regular investigator assessment and regular laboratory testing.
