Disorders of consciousness following a coma: what do we (not) know?

Thanks to advances in neurocritical care, an increased number of patients sustaining severe brain injury can now survive their brain lesions. Some of these patients may be unconscious for some time due to unarousal (coma), some will regain consciousness, while others will find themselves in different conditions collectively referred to as disorders of consciousness (i.e., unresponsive wakefulness syndrome and minimally conscious state). These non-communicating patients raise important diagnosis, prognosis and ethical issues. A number of clinical studies highlight the difficulty in making a correct diagnosis based on behavioral examinations. The increasing use of neuroimaging techniques allows improving clinical characterization of these patients and can help assess therapeutic treatment. These techniques also highlight possible dissociations between consciousness and responsiveness, and are facilitating a more accurate understanding of brain function in this challenging human population.
