A new study. Scientists assure that some resuscitated patients had clear memories of their death up to an hour following their heart stops. These people had brain patterns related to thinking and memory, investigators report in the journal Resuscitation.
According to this study led by researchers at the NYU Grossman School of Medicine, in cooperation with 25 hospitals, some cardiac arrest survivors described lucid death experiences that occurred while they were apparently unconscious. “Despite immediate treatment, less than 10% of the 567 patients studied, who received cardiopulmonary resuscitation in hospital, recovered sufficiently to be discharged from the hospital. However, four out of ten surviving patients remembered a certain degree of consciousness during CPR, not taken into account by standard measurements,” explain the researchers.
According to the findings, “in a subset of these patients, who received brain monitoring, nearly 40% had brain activity that returned to normal, or near normal, from a flat state, even an hour following starting CPR.” How to explain this phenomenon ? Through this study, researchers confirm that these death experiences were different from hallucinations, delusions, illusions, dreams, etc. The study authors hypothesize that the flat brain may suppress natural braking inhibitory systems. This phenomenon might open access to “new dimensions of reality” such as the recall of memories stored from early childhood until death.
A universal phenomenon
“Although doctors have long believed that the brain suffers permanent damage regarding 10 minutes following the heart stops supplying it with oxygen, our work has revealed that the brain may show signs of electrical recovery during a long period of ongoing CPR. This is the first major study to show that these memories and changes in brain waves may be signs of a universal phenomenon, shared elements of what are called near-death experiences,” explains the author. lead study, Sam Parnia, associate professor in the Department of Medicine at NYU Langone Health and director of critical care and life support research at NYU Langone.
Before concluding: “These experiences provide insight into a real, but little understood, dimension of human consciousness, which is revealed with death. The results may also guide the design of new ways to restart the heart or prevent brain damage and have implications for transplantation.
