קשקשן הזוי, מוכה מגלומניה, בכסות "הנגשה לכבדי ראיה" - אין שום ראיה לחיים לאחר החיים.
המחקר הקליני של הפרופסורים Parnia ו- Fenwick כלל מאות נסקרים מתאוששי התקף לב והלם טראומטי מסוגים שונים מרחבי העולם בבתי חולים מסונפים לאוניברסיטאות יוקרתיות, ולא העלה דבר פרט לחרס, חרסית וחול זך.
OBE ניתן לסטימולציה במעבדה ואינו מוכיח "ביקור חטוף" בעולם הבא.
דר' Eben Alexander פשוט נתקף התלהבות דתית המצויה אצל אוונגליסטים תינוקיים, ולא כל כך נצמד לאמת בספרו:
In a 2013 investigation of Alexander's story and medical background, Esquire magazine reported that before the publication of Proof of Heaven, Alexander had been terminated or suspended from multiple hospital positions, and had been the subject of several malpractice lawsuits, including at least two involving the alteration of medical records to cover up a medical error. He settled five malpractice suits in Virginia within a period of ten years.[10] The magazine also found what it claimed were discrepancies with regard to Alexander's version of events in the book. Among the discrepancies, according to an account of the Esquire article in Forbes, was that "Alexander writes that he slipped into the coma as a result of severe bacterial meningitis and had no higher brain activity, while a doctor who cared for him says the coma was medically induced and the patient was conscious, though hallucinating"[11].
Alexander further expanded on his NDE in the quarterly publication of the Congress of Neurological Surgeons[12] and the peer-reviewed Journal of the Missouri State Medical Association.[13][14]
Alexander's book has been criticized by scientists, including Sam Harris who described Alexander's NDE account as "alarmingly unscientific," and that "everything – absolutely everything – in Alexander's account rests on repeated assertions that his visions of heaven occurred while his cerebral cortex was 'shut down', 'inactivated', 'completely shut down', 'totally offline', and 'stunned to complete inactivity'. The evidence he provides for this claim is not only inadequate – it suggests that he doesn't know anything about the relevant brain science."[15] Neurologist and writer Oliver Sacks agreed with Harris, saying that "to deny the possibility of any natural explanation for an NDE, as Dr. Alexander does, is more than unscientific – it is antiscientific."..."The one most plausible hypothesis in Dr. Alexander's case...is that his NDE occurred not during his coma, but as he was surfacing from the coma and his cortex was returning to full function. It is curious that he does not allow this obvious and natural explanation, but instead insists on a supernatural one."[16] In 2012 Alexander responded to critics in a second Newsweek article.[17]
