In the intensive care unit (ICU), management of unresponsive patients with brain injury focuses on preventing secondary brain damage. Therapeutic strategies that directly promote the recovery of consciousness are urgently needed. In an investigator-initiated, randomized, placebo-controlled, double-blind, cross-over trial, we studied the effects of apomorphine and methylphenidate in ICU patients...

Near-death experiences (NDEs) are episodes of disconnected consciousness that typically occur in situations that involve an actual or potential physical threat or are perceived as such, and the experiences are characterized by a rich content with prototypical mystical features. Several explanatory theories for NDEs have been proposed, ranging from psychological or neurophysiological to...

Migraine aura, near-death experiences (NDEs), and rapid eye movement (REM) sleep intrusions might share common mechanisms. Here, we investigated the prevalence of NDEs and REM sleep intrusions in people with migraine. We hypothesized that NDEs and REM sleep intrusions are more prevalent in migraine patients with aura than in those without. We conducted a prospective cross-sectional cohort study...

Parnia et al. recently published suggestions for the study of death and experiences recalled in a near‐death context. We have serious reservations about the authors’ statements. In this commentary, we discuss the omissions and knowledge gaps inherent to the authors’ paper, which among others include incorrect neurological claims about brain death and misunderstandings regarding the terminology...

Abstract Near-death experiences are known from all parts of the world, various times and numerous cultural backgrounds. This universality suggests that near-death experiences may have a biological origin and purpose. Adhering to a preregistered protocol, we investigate the hypothesis that thanatosis, aka death-feigning, a last-resort defense mechanism in animals, is the evolutionary origin of...

Purpose of reviewNear-death experiences (NDEs) are conscious perceptual experiences, including self-related emotional, spiritual, and mystical experiences, occurring in close encounters with death or in non-life-threatening situations. The origin of NDEs remains unknown. Here, we review recent advances in the understanding of NDE semiology and pathophysiology.Recent findingsRecent prospective...

ABSTRACT Background Near-death experiences have fascinated humans for centuries, but their origin and prevalence remain unknown. Methods Using an online crowdsourcing platform, we recruited 1034 lay people from 35 countries to investigate the prevalence of near-death experiences and self-reported REM sleep intrusion. Reports were validated using the Greyson Near-Death Experiences Scale (GNDES)...

The origin and prevalence of near-death experiences are unknown. A recent study suggested a link with REM sleep intrusion but was criticized for its selection of control participants. We therefore assessed the association of REM intrusion and near-death experiences with different methods. Using a crowd-sourcing platform, we recruited 1,034 lay people from 35 countries to investigate the...

Near-death experiences (NDE) occur with imminent death and in situations of stress and danger but are poorly understood. Evidence suggests that NDE are associated with rapid eye movement (REM) sleep intrusion, a feature of narcolepsy. Previous studies further found REM abnormalities and an increased frequency of dream-enacting behavior in migraine patients, as well as an association between...
