Near-death studies
Near-death studies is a school of psychology and psychiatry that studies the phenomenology and after-effects of a Near-death experience (NDE).

# NDE (Near-death experience)
The NDE is an experience reported by people who have come close to dying in a medical or non-medical setting. The phenomenon is considered to be a fairly common occurrence in modern clinical settings (Lukoff, Lu & Turner, 1998) and according to a Gallup poll aproxiomately eight million Americans claim to have had a near-death experience (Mauro, 1992). An NDE may include such factors as: an out-of-body-experience, visions of deceased relatives, visions of religious figures or beings of light, transcendence of ego and spatiotemporal boundaries, the sense of moving up or through a narrow passageway ("Tunnel experience"), life review, and other transcendental experiences (Lukoff, Lu & Turner, 1998; Greyson, 2003; Mauro, 1992). The phenomenology of a NDE usually includes physiological, psychological and transcendental factors that come together to form an overall pattern when numerous NDE reports are considered together. It is this pattern that is one of the main objects of interest for Near-Death studies. NDE-researchers have also found that the NDE is not a uniquely western experience. The core experience seems to be similar across cultures, but the details of the experience (figures, beings, scenery), and the interpretation of the experience, varies a lot from culture to culture (Mauro, 1992).

# Research - History and background
Interest in this field of study was originally spurred by the research of such pioneers as Elisabeth Kubler-Ross, George Ritchie, and Raymond Moody Jr. Moody's book Life after Life, which was released in 1975, brought a lot of attention to the topic of NDEs (Mauro, 1992). This was soon to be followed by the establishment of the International Association for Near-death Studies (IANDS). IANDS was founded in Connecticut (United States) in 1978 in order to meet the needs of early researchers and experiencers within this field of research. Today the association includes researchers, health care professionals, NDE-experiencers and people close to experiencers, as well as other interested people. One of its main goals is to promote responsible and multi-disciplinary investigation of near-death and similar experiences. The organization is recognized by the Internal Revenue Service as a 501(c)(3) nonprofit organization (IANDS, printable brochure).
Later researcers, such as Bruce Greyson, Kenneth Ring and Michael Sabom, introduced the study of Near-Death experiences to the academic setting. The medical community has been somewhat reluctant to address the phenomenon of NDE's and grant money for research has been scarce (Mauro, 1992). However, although the research was not always welcomed by the general academic community, both Greyson and Ring made significant contributions in order to increase the respectability of Near-Death research (IANDS, printable brochure). Major contributions to the field include the construction of a Weighted Core Experience Index (Ring, 1980) in order to measure the depth of the Near-Death experience, and the construction of the Near-death experience scale (Greyson, 1983) in order to differentiate between subjects that are more or less likely to have experienced a classical NDE. The NDE-scale also aims to differentiate between a true NDE and syndromes or stress responses that are not related to a NDE. Greysons NDE-scale was later found to fit the Rasch rating scale model (Lange, Greyson & Houran, 2004).
Greyson (1997) has also brought attention to the near-death experience as a focus of clinical attention, while Morse et.al (1985; 1986) have investigated Near-death experiences in a pediatric population. Ring has found that a typical set of values and belief changes often accompany the life of Near-Death experiencers. Among these after-effects are changes in personality and outlook on life such as a greater appreciation for life, higher self-esteem, greater compassion for others, a heightened sense of purpose and self-understanding, desire to learn, elevated spirituality, greater ecological sensitivity and planetary concern, a feeling of being more intuitive (sometimes psychic), increased physical sensitivity, diminished tolerance to light, alcohol and drugs, a feeling that the brain has been "altered" to encompass "more", and a feeling that one is now using the "whole brain" rather than just a small part (Mauro, 1992).

# Journal of Near-Death Studies
IANDS is also responsible for the publishing of the Journal of Near-Death Studies, the only scholarly journal in the field. It is cross-disciplinary and published quarterly. Between the years of 1997-2003 the journal was published by Kluwer Academic Publishers, but this arrangement was discontinued upon completion of Volume 21. Since 2003 the Journal is published by The International Association for Near-Death Studies, printed and distributed by Allen Press. IANDS also publishes the newsletter Vital Signs and maintains an archive of near-death case histories for research and study.
