Area of Science:

  • Neuroscience
  • Biomedical Engineering
  • Rehabilitation Medicine

Background:

  • Recent neuroimaging reveals covert awareness in some patients with disorders of consciousness (DoC).
  • This highlights the potential of brain-computer interfaces (BCIs) for diagnosis in unresponsive patients.

Purpose of the Study:

  • To review current EEG-based BCIs for assessing and assisting patients with DoC.
  • To identify key areas for development to enable feasible application in this challenging patient group.

Main Methods:

  • Consideration of major BCI types: P3 potential, sensorimotor rhythms, steady-state oscillations, and slow cortical potentials.
  • Overview of relevant literature for each BCI type.
  • Evaluation of BCI merits for DoC applications.

Main Results:

  • Various BCI designs exist for communication in paralyzed patients, with potential for DoC.
  • Key challenges include limitations in stimulation modality, feedback, user training, and consistency.
  • Overcoming these challenges is crucial for BCI efficacy in DoC.

Conclusions:

  • Future research must address technical and practical challenges for reliable bedside implementation.
  • Enhancing BCI reliability and usability is essential for clinical translation.
  • Continued innovation is needed to improve outcomes for patients with DoC.
