Research on clinically undetected consciousness is easily subject to overinterpretation and sensationalism that the authors certainly do not intend. In discussions with families and in physicians' capacity as spokespersons to society on these matters, three points should be emphasized. First, in this study, brain activation was detected in very few patients. Second, activation was found only in some patients with traumatic brain injury, not in patients with global ischemia and anoxia. Third, cortical activation does not provide evidence of an internal "stream of thought" (William James's term), memory, self-awareness, reflection, synthesis of experience, symbolic representations, or ? just as important ? anxiety, despair, or awareness of one's predicament. Without judging the quality of any person's inner life, we cannot be certain whether we are interacting with a sentient, much less a competent, person. Moreover, persons who look to this study to justify continued and unqualified life support in all unresponsive patients are missing the focus of the findings.
