Posttraumatic stress symptoms following near-death experiences.

Persons who report "near-death experiences" (NDEs) acknowledge more intrusive symptoms of posttraumatic stress disorder (PTSD) than those who came close to death without NDEs, but not more avoidance symptoms, suggesting a nonspecific stress response. Although dissociation generally increases vulnerability to PTSD, the positive affect that distinguishes NDEs from other dissociative experiences may mitigate subsequent PTSD symptoms.

Dissociation in people who have near-death experiences: out of their bodies or out of their minds?

BACKGROUND: Some people who come close to death report having experiences in which they transcend the boundaries of the ego and the confines of time and space. Such near-death experiences (NDEs) share some features with the phenomenon of dissociation, in which a person's self identity becomes detached from bodily sensation. This study explored the frequency of dissociative symptoms in people who had come close to death. METHODS: 96 individuals who had had self-reported NDEs, and 38 individuals who had come close to death but who had not had NDEs completed a mailed questionnaire that included a measure of "depth" of near-death experience (the NDE scale) and a measure of dissociative symptoms (the Dissociative Experiences Scale). Median scores in the two groups were compared with Mann-Whitney U tests. The association between depth of NDE and dissociative symptoms was tested by Spearman's rank-order correlation between scores on the NDE scale and the dissociative experiences scale. FINDINGS: People who reported NDEs also reported significantly more dissociative symptoms than did the comparison group. Among those who reported NDEs, the depth of the experience was positively correlated with dissociative symptoms, although the level of symptoms was substantially lower than that of patients with pathological dissociative disorders. INTERPRETATION: The pattern of dissociative symptoms reported by people who have had NDEs is consistent with a non-pathological dissociative response to stress, and not with a psychiatric disorder. A greater understanding of the mechanism of dissociation may shed further light on near-death and other mystical or transcendental experiences.

The near-death experience as a focus of clinical attention.

Near-death experiences (NDEs) often produce profound changes in attitudes and behavior that can lead to psychosocial and psychospiritual problems. The diagnostic label of religious or spiritual problem, included in DSM-IV under the category of other conditions that may be a focus of clinical attention, was originally proposed to encompass NDEs and their aftereffects. Four cases are discussed in which patients presented with NDE-related problems, and differential diagnosis and current treatment strategies are reviewed. The inclusion of this new diagnostic category in the DSM-IV permits differentiation of NDEs and similar experiences from mental disorders and may lead to research into more effective treatment strategies.

Varieties of near-death experience.

Near-death experiences are profound subjective events frequently reported by individuals who have come close to death. They are of importance to mental health professionals, not only because they often happen to patients under our care, but because they have been reported to produce widespread and long-lasting changes in values, beliefs, and behavior that dramatically affect the experiencers' attitudes toward living and dying (Bates and Stanley 1985; Bauer 1985; Flynn 1982; Greyson 1983b; Noyes 1980; Ring 1984). Several studies, including surveys of recently resuscitated hospitalized patients (Ring 1980; Sabom 1982) and a nationwide poll of the general population (Gallup and Proctor 1982) have estimated that near-death experiences are reported by 30%-40% of individuals who come close to death, or about 5% of the adult American population.

Distressing near-death experiences.

Most reported near-death experiences include profound feelings of peace, joy, and cosmic unity. Less familiar are the reports following close brushes with death of experiences that are partially or entirely unpleasant, frightening, or frankly hellish. While little is known about the antecedents or aftereffects of these distressing experiences, there appear to be three distinct types, involving (1) phenomenology similar to peaceful near-death experiences but interpreted as unpleasant, (2) a sense of nonexistence or eternal void, or (3) graphic hellish landscapes and entities. While the first type may eventually convert to a typical peaceful experience, the relationship of all three types to prototypical near-death experiences merits further study. The effect of the distressing experience in the lives of individuals deserves exploration, as the psychological impact may be profound and long-lasting.

Incidence of near-death experiences following attempted suicide.

Near-death experiences (NDEs), profound subjective experiences occurring during a close brush with death and containing transcendental or mystical elements, have been reported to reduce suicidal ideation, despite their "romanticization" of death. Among 61 consecutive hospital admissions for attempted suicide, 16 patients (26.2%) reported NDEs precipitated by the attempt. NDEs were not significantly associated with any demographic factors. In light of the frequency of NDEs following attempted suicide, further studies are indicated in regard to the effect of those experiences on subsequent suicidal behavior.

A typology of near-death experiences.

Cluster analysis of 89 near-death experiences yielded three discrete types of such experiences: transcendental, affective, and cognitive. Demographic variables did not differentiate individuals having these different types of experiences, but cognitive near-death experiences were less frequent following anticipated near-death events.

The near-death experience scale. Construction, reliability, and validity.

Near-death experiences (NDEs) have been described consistently since antiquity and more rigorously in recent years. Investigation into their mechanisms and effects has been impeded by the lack of quantitative measures of the NDE and its components. From an initial pool of 80 manifestations characteristic of NDEs, a 33-item scaled-response preliminary questionnaire was developed, which was completed by knowledgeable subjects describing their 74 NDEs. Items with significant item-total score correlations that could be grouped into clinically meaningful clusters constituted the final 16-item NDE Scale. The scale was found to have high internal consistency, split-half reliability, and test-retest reliability; was highly correlated with Ring's Weighted Core Experience Index; and differentiated those who unequivocally claimed to have had NDEs from those with qualified or questionable claims. This reliable, valid, and easily administered scale is clinically useful in differentiating NDEs from organic brain syndromes and nonspecific stress responses, and can standardize further research into mechanisms and effects of NDEs.

The psychodynamics of near-death experiences.

Near-death experiences (NDEs), profound transcendental events experienced on the threshold of death, may be interpreted on several levels from the neurophysiological to the eschatological. Independent of other levels of interpretation, a psychological analysis of NDEs produces meaningful and researchable psychodynamic precipitants and sequelae. A number of psychological mechanisms are discussed, which overdetermine the prototypical NDE, and objections to psychological interpretations of the phenomenon are considered. Further exploration of the psychological aspects of NDEs may yield clinically useful techniques in suicide prevention and in the treatment of terminal and bereaved patients.

Near-death experiences and personal values.

Near-death experiences reportedly foster value transformations and decrease suicidal ideation. Eighty-nine survivors of near-death experiences judged values related to material and social success as less important than did 175 control subjects. Decathexis of personal failures may account for the reported suicide-inhibiting effect.

Near-death experiences and attempted suicide.

Attempted suicide is correlated with an increase subsequent risk of committed suicide. However, preliminary data and psychodynamic hypotheses suggest that serious suicide attempts followed by transcendental near-death experiences (NDEs) may decrease rather than increase subsequent overt suicide risk, despite the NDEs' apparent "romanticization" of death. Studies of NDEs and of their influence on suicidal ideation are proposed which may yield greater understanding of self-destructive urges and new strategies of suicide prevention.

The phenomenology of near-death experiences.

The authors studied retrospectively 78 reports of "near-death experiences using subjects narratives and questionnaires, interviews, and medical records. Prior experiences suggestive of transcendence of death were more common among these subjects than among control populations, but prior experiences suggestive of extrasensory phenomena were less common. Subsequent changes in attitudes were more common than among subjects in other studies who had had psychic experiences. The influence of cultural and psychological factors, sensory deprivation, and reflex adaptive responses to stress explain some but not all of the features of near-death experiences. Their potential value to our conceptualization of dying and to suicide prevention and the care of the terminally ill justifies further investigation.

Telepathy in mental illness: deluge or delusion?

The belief that one can read others' minds has long been considered a symptom of psychosis, despite reports in the parapsychological literature of veridical telepathy. All patients admitted to an inpatient psychiatric unit were screened for paranormal beliefs, and those claiming telepathic abilities were tested in a free-response ESP task. Eighteen per cent of the inpatient population claimed telepathic abilities; of the nine patients who completed the task, none performed above chance expectations. Higher frequencies of paranormal experiences than those reported previously in the psychiatric literature were attributed to the context of the study. Schneider's first rank symptoms and a belief in telepathy discriminated schizophrenics more reliably than other paranormal experiences. Possible psychodynamics of delusions of telepathy were discussed in view of the predominance of women and younger men reporting them, as were the possible effects of such research on patients' delusions.
