Disorders of consciousness present a variety of ethical concerns. Most obvious is the lack of consent in any treatment decisions. Patients in PVS or MCS are not able to decide for the possibility of withdrawal of life-support. It is also a general question whether they should receive life-sustaining therapy and, if so, for how long? The problems regarding a patient's consent also account for neuroimaging studies. Without patient's consent, such studies are perceived as unethical. Additionally only few patients have created advance directives before losing decision-making capacity. Typically approval must be obtained from family or legal representatives depending on governmental and hospital guidelines. But even with the consent of representatives, researchers have been refused grants, ethics committee approval and publication.

Social issues arise from the enormous costs that are caused by people with disorders of consciousness. Especially chronic comatose and vegetative patients, when recovery is highly unlikely and treatment in the ICU is considered futile by clinicians. In addition to the aforementioned problems, the question rises why medical resources were being used not for the broader public good but for patients who seemed to have only little to gain from them. Still research is everything but sure about the irreversibility of these conditions. Some studies demonstrated that some patients suffering from disorders of consciousness may be aware despite clinical unresponsiveness. These recent findings could have a major impact on ethical and social issues.
