Advances in resuscitation science have indicated that, contrary to perception, death by cardiorespiratory criteria can no longer be considered a specific moment but rather a potentially reversible process that occurs after any severe illness or accident causes the heart, lungs, and brain to stop functioning. The resultant loss of vital signs of life (and life processes) is used to declare a specific time of death by physicians globally. When medical attempts are made to reverse this process, it… Expand

Neuroscience and awareness in the dying human brain: Implications for organ donation practices.
TLDR
It is argued that the capacity for awareness may not be irreversibly lost after a relatively brief period of cessation of systemic circulation, and empirical data is outlined in support of the claim that awareness without wakefulness may be present. Expand
Do out-of-body and near-death experiences point towards the reality of nonlocal consciousness? A critical evaluation
In recent years there was a steady flow of academic studies claiming that the mind or consciousness can function independently from a working brain. Such research is presented with great confidenceExpand

In the present chapter, death is considered from three different but complementary points of view. Firstly, it is dealt with in the framework of three different perspectives: the diagnostic-medicalExpand
Semiology and Mechanisms of Near-Death Experiences
TLDR
Recent prospective studies confirm that NDEs reflect a spectrum of highly distinctive memories which are associated with negative or positive emotions and can be influenced by the nature of the causal event, but the temporal sequence with which these images unfold is variable. Expand
Donation after brain circulation determination of death
TLDR
In cases of circulatory cessation, such as occurs in DBCDD, death can be defined as the permanent cessation of brain functions, determined by the permanent stoppage of brain circulation. Expand
Near-death experiences, posttraumatic growth, and life satisfaction among burn survivors
TLDR
Survivors of large burns may face positive and negative psychological after-effects from close-to-death injuries and posttraumatic growth (PTG) and life satisfaction afterwards and social workers and other health providers need to be comfortable helping burn survivors discuss any NDEs and process these through survivors’ spirituality and religious belief systems as they recover. Expand
The life review experience: Qualitative and quantitative characteristics
TLDR
Qualitative analysis showed the LRE to manifest several subtypes of characteristics in terms of order, continuity, the covered period, extension to the future, valence, emotions, and perspective taking, which suggests that a representation of life-events as a continuum exists in the cognitive system, and maybe further expressed in extreme conditions of psychological and physiological stress. Expand
Scientific and Ethical Challenges in End-of-Life Organ Donation.
TLDR
Clinicians should be cautious of implementing recommendations that are grounded in consensus-based expert opinions particularly when recommendations contravene contemporary scientific evidence. Expand
Compressed Life Review: Extreme Manifestation of Autobiographical Memory in Eye-Tracker
TLDR
The data suggest that CLR-like phenomenology may be successfully induced by triggering short-term access to the verbally cued SDMs and may be associated with specific patterns of visual activity that are not reportedly involved with deliberate autobiographical retrieval. Expand

Near death experiences in cardiac arrest: visions of a dying brain or visions of a new science of consciousness.
TLDR
This article will review published research examining brain physiology and function during cardiac arrest as well as its potential relationship with near death experiences during this time, and explores the contribution that neardeath experiences during cardiac Arrest may make to the wider understanding of human consciousness. Expand
Near-death-experiences in out-of-hospital cardiac arrest survivors. Meaningful phenomena or just fantasy of death?
TLDR
Good out-of-hospital cardiac arrest survivors were interviewed, with documented time-intervals between call for help and restoration of spontaneous circulation, yet without obvious brain damage or known, psychiatric history. Expand
Near-death experiences.
TLDR
In a near death experience, the patient is clinically dead, but is then revived and able to describe what " death was like, yet the person was conscious, aware and watching as attempts were made to resuscitate him. Expand
Do reports of consciousness during cardiac arrest hold the key to discovering the nature of consciousness?
  • S. Parnia
  • Psychology, Medicine
  • Medical hypotheses
  • 2007
TLDR
The broad theories for the causation of consciousness are reviewed as a novel method to study consciousness during cardiac arrest may provide a unique experimental method to determine the nature of human mind and consciousness as well as its relationship with the brain. Expand
Conscious mental activity during a deep hypothermic cardiocirculatory arrest?
TLDR
A retrospective study in patients who went deep hypothermic cardiocirculatory arrest at ôpital Sacré-Coeur (a research hospital affiliated with the Univerité de Montréal) between 2005 and 2010 to estimate the prevalence of conscious ental events during DHCA. Expand
Childhood near-death experiences.
TLDR
A neurophysiologic hypothesis as to the cause of NDEs is presented and it is suggested that a core NDE, triggered by the process of dying or resuscitation efforts, may be a natural developmental experience. Expand
Cerebral blood flow after cardiac arrest.
TLDR
Results were recently confirmed in a retrospective, multicenter observational study showing that the implementation of mild therapeutic hypothermia in Dutch intensive care units (ICUs) was associated with a 20 % relative reduction in hospital mortality. Expand
Near-death experience in survivors of cardiac arrest: a prospective study in the Netherlands
TLDR
The cause of this experience and factors that affected its frequency, depth, and content are established and why so few cardiac patients report NDE after CPR is investigated. Expand
History of the Science of Cardiopulmonary Resuscitation
Through much of recorded history, resuscitation was forbidden. Although written accounts of resuscitation can be found, it is clear that successful reversal of death was thought to have beenExpand
A qualitative and quantitative study of the incidence, features and aetiology of near death experiences in cardiac arrest survivors.
TLDR
Memory are rare after resuscitation from cardiac arrest, and the majority of those that are reported have features of NDE and are pleasant, which raises questions about the possible relationship between the mind and the brain. Expand
