An icebreaker

A Dutch cardiologist tracked 344 cardiac-arrest survivors and published the results in The Lancet in 2001: 18% reported a near-death experience, with no medical factor explaining who did or didn't. A critic argues the study leans too hard on gaps in brain science.

Worth knowing · 1 of 5

What did the study actually track?

Starting in 1988, he and colleagues followed 344 consecutive patients resuscitated after cardiac arrest at ten Dutch hospitals, interviewing survivors soon after and again at two and eight years to see whether reported experiences changed their lives.

What were the core findings?

18% of survivors reported a near-death experience, most commonly awareness, deep peace, or seeing a light; medical factors like drugs, oxygen levels, and time unconscious did not reliably predict who reported one.

What did he argue this ruled out?

He argued that if lack of oxygen alone explained the experiences, most or all patients should have reported one, since all had suffered comparable oxygen deprivation, and used that gap to question a simple physiological explanation.

What's the strongest published criticism of the study?

A cognitive neuroscientist's detailed 2008 critique credited the study with useful data but argued it misread what a flat EEG during cardiac arrest can and can't rule out, and leaned too far past what the observations actually support.

Is this accepted as proof of anything beyond the brain?

No. It remains a real, published clinical study whose central puzzle, why only some patients report the experience, is still unresolved; most researchers still expect a physiological account will eventually be found.

Words to know

Near-death experience (NDE)A vivid, often peaceful reported experience occurring during a close brush with death, such as cardiac arrest.

Cardiac arrestThe sudden stopping of the heart, cutting off blood and oxygen to the brain within seconds.

AnoxiaA total lack of oxygen to tissue, one proposed physiological explanation for near-death experiences.

More words

EEG flatlineA reading showing no detectable electrical brain activity, central to the debate over what the brain can do during arrest.

Pim van Lommel · Cardiologist who led the study

Publishing his findings in The Lancet in 2001, he reported that 18% of 344 resuscitated cardiac-arrest patients recalled a near-death experience, and argued that no medical factor tested explained why only some patients did.

Jason Braithwaite · Cognitive neuroscientist who critiqued the study

In a 2008 published critique he credited the study with contributing useful observational data, but argued it contained factual and logical errors, including overreliance on EEG readings as proof of total brain inactivity during arrest.

Dick Swaab · Neurobiologist who reviewed his later book

In his 2010 book on the brain, he credited near-death experiences as real experiences but argued van Lommel's later book set aside well-established biology, including Nobel-winning findings on heredity and memory, without scientific argument.
