Neurology of consciousness impairments

Résumé

Probing consciousness in non-communicating patients at bedside can be very challenging. In this chapter, we describe some of the key goals, caveats and pitfalls of the evaluation of consciousness in non-communicating patients. First, we will address the importance of neurological and behavioral examination , and then briefly outline the current developments of functional brain-imaging tools able to provide important additional evidence. Current approaches include both: (i) active paradigms in which a patient is asked to perform a specific cognitive task; (ii) " resting state " conditions in which the spontaneous patterns of brain-activity can be instructive of patients conscious state; and (iii) passive paradigms in which cortical functional connectivity can be explored by recording, for instance, EEG in response to focal transmagnetic stimulation (TMS) pulses.
