Recent results from neuroimaging appear to indicate that some patients in a vegetative state have partially intact awareness. These results may demonstrate misdiagnosis and suggest the need not only for alternative forms of treatment, but also for the reconsideration of end-of-life decisions in cases of disorders of consciousness. This article addresses the second consequence. First, I will discuss which aspects of consciousness may be involved in neuroimaging findings. I will then consider various factors relevant to ethical end-of-life decision-making, and analyse (...) whether and to what extent the above consequence applies to these factors. It will be shown that knowledge of the existence of partial awareness in patients with disorders of consciousness only influences end-of-life decision-making if certain background assumptions are made.

The recent ruling from England on the case of M is one of very few worldwide to consider whether life-sustaining treatment, in the form of clinically assisted nutrition and hydration, should continue to be provided to a patient in a minimally conscious state. Formally concerned with the English law pertaining to precedent autonomy (specifically advance decision-making) and the best interests of the incapacitated patient, the judgment issued in M's case implicitly engages with three different accounts of the value of human (...) life, which respectively emphasise its self-determined, intrinsic and instrumental value. The judge appeared to be most persuaded by the intrinsic value of life and he concluded that treatment ought to continue. Assessing whether his approach or conclusion were ethically appropriate involves significant substantive and evidential questions regarding where the burden of proof should lie and what standard of proof should be required when decisions are to be made about the fates of patients inhabiting ‘twilight worlds’.
