Detection of rhythmic brain waves suggestive of near-death experiences
Note: This presentation is titled “AWAreness during REsuscitation II: a multicenter study of consciousness and awareness in cardiac arrest,” and is scheduled to be presented during the resuscitation science symposium at the American Heart Association’s Scientific Sessions 2022 on Sunday, Nov. 6at the Hyatt Regency Chicago Hotel in Chicago.
NEW YORK, Nov. 6, 2022 /PRNewswire/ — One in five people who survive cardiopulmonary resuscitation (CPR) after cardiac arrest may describe lucid experiences of death that occurred while they were seemingly unconscious and on the brink of death, a new study shows.
Led by researchers at NYU Grossman School of Medicine and elsewhere, the study involved 567 men and women whose hearts stopped beating while hospitalized and who received CPR between May 2017 and March 2020 in the United States and United Kingdom. Despite immediate treatment, fewer than 10% recovered sufficiently to be discharged from hospital.
Survivors reported having unique lucid experiences, including a perception of separation from the body, observing events without pain or distress, and a meaningful evaluation of life, including of their actions, intentions and thoughts toward others. The researchers found these experiences of death to be different from hallucinations, delusions, illusions, dreams or CPR-induced consciousness.
The work also included tests for hidden brain activity. A key finding was the discovery of spikes of brain activity, including so-called gamma, delta, theta, alpha and beta waves up to an hour into CPR. Some of these brain waves normally occur when people are conscious and performing higher mental functions, including thinking, memory retrieval, and conscious perception.
“These recalled experiences and brain wave changes may be …
