Evaluation of Consciousness by Brain-computer Interface in Severely Brain Damaged Patients

France9 participantsStarted 2018-03-06

Plain-language summary

The objective of this study is to show that the measurement of auditory and vibro-tactile evoked potentials, or the recording of the EEG signal during a motor imaging task, can be used in routine clinical situations to explore the state of consciousness of subjects in Non-responsive Awakening (or Chronic Vegetative State) or in Minimal Consciousness (or relational state) after a severe brain injury. Assumptions : * Correlation between patient response rates obtained with the brain-machine interface and their clinical consciousness score (Coma Recovery Scale Revised score) * Differentiation of the parameters of the evoked potentials P300 between patients in a vegetative state and those in a state of minimal consciousness
