About this study
Official title: Prognosis of Acute DOC
Prior research has indicated a link between outcomes in patients with disorders of consciousness (DOC) and their responses to emotional auditory stimuli. Given the high degree of uncertainty in acute situations, this study plans to record EEG responses and observe microexpressions in DOC patients during exposure to auditory stimuli, with the aim to identify more reliable prognostic indicators. The goal is to uncover potential patterns or signals that can contribute to a more comprehensive understanding of a patient's condition, and thereby provide more accurate prognostication.
Read the detailed description
This study intends to probe the potential of electroencephalography (EEG) and microexpression analysis for predicting the outcomes of acutely unresponsive patients within the intensive care unit (ICU). Previous research has illuminated a relationship between patients' emotional responses to auditory stimuli and their prognosis. However, the predictive utility of these responses in the context of acute conditions remains largely unexplored.
At the onset of the study, participants will undergo EEG monitoring while exposed to a pre-determined set of emotional auditory stimuli. Additionally, the patients' facial expressions will be captured via video for subsequent microexpression analysis.
Follow-up assessments of the patients' status will be conducted at three, six, and twelve-month intervals. Using cutting-edge analytical techniques, the goal is to decode these EEG and microexpression responses. This study aims to identify possible correlations between these findings, the patients' diagnoses, and their respective outcomes over time.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| EEG and Microexpression Analysis | Participants will be acutely unresponsive ICU patients. They will undergo non-invasive observational procedures, including EEG monitoring during exposure to emotional auditory stimuli, and concurrent video recording for microexpression analysis. Patient outcomes will be assessed at three, six, and twelve-month intervals post-initial observation. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Glasgow Outcome Scale-Extended (GOS-E)
GOS-E is an extended version of the Glasgow Outcome Scale (GOS), which was developed to provide a more detailed assessment of patient functionality and quality of life after experiencing such an injury. It has eight categories: Dead, Vegetative State, Lower Severe Disability, Upper Severe Disability, Lower Moderate Disability, Upper Moderate Disability, Lower Good Recovery, and Upper Good Recovery.
Measured: Month 1
Glasgow Outcome Scale-Extended (GOS-E)
GOSE will be assessed 3 months after brain injury.
Measured: Month 3
Glasgow Outcome Scale-Extended (GOS-E)
GOSE will be assessed 6 months after brain injury.
Measured: Month 6
Glasgow Outcome Scale-Extended (GOS-E)
GOSE will be assessed 12 months after brain injury.
Measured: Month 12
