Due to advances in resuscitation and critical care, many people are surviving near-death experiences. Survivors’ recalled experiences are not consistent with hallucinations, but instead, follow a specific narrative arc involving perception.

Scientific advances in the 20th and 21st centuries have led to a major evolution in the understanding of death. At the same time, for decades, people who have survived an encounter with death have recalled unexplained lucid episodes involving heightened consciousness and awareness. These have been reported using the popular—yet scientifically ill-defined—term “near-death experiences”.

A multidisciplinary team of national and international leaders, led by Sam Parnia, MD, Ph.D., director of Critical Care and Resuscitation Research at NYU Grossman School of Medicine, have published “Guidelines and Standards for the Study of Death and Recalled Experiences of Death,” a multi-disciplinary consensus statement and proposed future directions in the Annals of the New York Academy of Sciences.

This study, which examined the accumulated scientific evidence to date, represents the first-ever, peer-reviewed consensus statement for the scientific study of recalled experiences surrounding death.

The researchers on the study represent many medical disciplines, including the neurosciences, critical care, psychiatry, psychology, social sciences and humanities, and represent many of the world’s most respected academic institutions including Harvard University, Baylor University, University of California Riverside, University of Virginia, Virginia Commonwealth University, Medical College of Wisconsin, and the Universities of Southampton and London.
