Just because mid-morning TV talk shows believe in it, does this mean it can't be true? Many skeptical people take that attitude toward the notion of the "near death experience," in which a person who almost dies - usually, a heart-attack victim - after revival reports not terror but beautiful visions, inner calm and even a sense of a door opening to an afterlife. Generally, the near death experience gets the most play on sensationalist talk shows and drek like "Crossing Over with John Edward," the supposed talk-to-the-dead program that, critics never fail to point out, airs on the Sci-Fi Channel. Respectable medical researchers have had comparatively little to say about the near death experience.

Until now, that is. A study just published in The Lancet, England's most prestigious medical journal, provides what may be the first hard-science confirmation that many people who almost die do experience something haunting at the boundary of life. Conducted by Pim van Lommel, a cardiologist at an Amsterdam hospital, the study concerned 344 patients who were resuscitated following cardiac arrest in Dutch hospitals. Some 18 percent of the patients told interviewers they had a near death experience; 12 percent had what van Lommel called a "core experience," not just warm feelings but elaborate perception of the beginning of an afterlife.

What's important about the new study is that it was done "prospectively." Most near death research is "retrospective," involving seeking out people who claim to have had such an experience, and talking to them months or years after the fact. From a research standpoint, subjects like this are "self-selected" - people who already think something, not a random trial - and the delay means they may have had plenty of time to imagine things. The Dutch effort, in contrast, involved interviewing everyone who had been resuscitated in 10 local hospitals during the study period, and simply asking them if they had any recollections. Interviews were conducted as soon as the patients were well enough to talk, and patients were not told the topic of the study, merely that researchers wanted to know if they remembered anything. This avoided any "prompting" effect.

Thus a finding that 18 percent of men and women revived at the point of death had impressions of light or beauty seems important. Something, must be going on. And it's going on more and more. If it seems to you that reports of near death experiences are increasing - you're right, they are. Only in recent decades did physicians acquire the ability to resuscitate patients at the point of death. Now that this happens in hospitals every day, there are thousands of people walking around who have been almost dead. Eventually there may be millions.

The something going on in near death cases might be physiological, of course. Researchers have previously speculated that the near death experience might be an artifact of cerebral anoxia, or lack of oxygen to the brain. As oxygen falters, this thinking goes, the brain begins to shut down, and misfirings of synapses create illusions of light or music. The Dutch study seems to rule out this idea, however. All patients in the study suffered some degree of cerebral anoxia before revival, but only 18 percent had a near death experience. As The Lancet, notes, if the near death experience is caused by cerebral anoxia, "most patients who have been clinically dead should report one." Instead most of the clinically dead patients did not report a near death experience. Brain oxygen problems therefore seem unlikely as the cause.

Skeptics of near death claims also point out that ketamine, an anesthetic, sometimes causes surgery patients to experience visions of beauty or light. This must be a physiological response. But the subjects in the Dutch study were heart-attack victims, not surgery patients: they were not administered ketamine.

What happened to van Lommel's subjects who did have near death experiences? They reported visions of beauty or light, loss of fear of death, a sense of being welcomed to a wonderful place, and in one case an "out of body" experience. The last involved a 44-year-old man brought to the hospital comatose; as resuscitation began, a nurse removed dentures from his mouth. Later when the patient has recovered he sees the nurse and asks for his dentures back. But the only time the nurse had been in his presence, he had been unconscious and near death; how did he know what the nurse looked like?
