AWARE II Final Publication – speculation does not imply association
[and finally the answer to my 3.5 year old vital question!]
Firstly, congratulations to Dr Sam Parnia and the team of researchers who conducted this awesome study which is the first study ever to find biomarkers of consciousness during CPR in the absence of heartbeat. Let me repeat that because it is a huge achievement. This is the first study to ever find markers of consciousness during CPR. I can just see the materialists entering a wild feeding frenzy, their eyes rolling back in ecstasy as they chew on this headline, but what they might think is raw fillet may turn out to be TOFU (no offence to vegans – just a matophor).
This is a pre-proof, rather than a pre-print (which was put out there earlier in the year). That means it is only a proofread away from full publication rather than a serious review and edit. This is for all intents and purposes the final publication that will appear in Resuscitation. The link is below:
Essentially the results are not much different from those presented at AHA last November, and in the pre-print mentioned above and found in my summary in the following link, WITH ONE VERY BIG EXCEPTION.
Before I draw your attention to the exception which answers the question I sent to the Parnia lab in January 2020, I will just remind you all of the key findings:
- The study finished recruiting from 25 sites, predominantly located in the UK or US, in March 2020 (at least for this analysis – is it the final analysis? They are still recruiting according to NYU website).
- The key findings are summarized as follows and all the quotations are from the citation beneath:
Of 567 IHCA, 53(9.3%) survived, 28 of these (52.8%) completed interviews, and 11(39.3%) reported CA memories/perceptions suggestive of consciousness. Four categories of experiences emerged: 1) emergence from coma during CPR (CPR-induced consciousness [CPRIC]) 2/28(7.1%), or 2) in the post-resuscitation period 2/28(7.1%), 3) dream-like experiences 3/28(10.7%), 4) transcendent recalled experience of death (RED 6/28(21.4%)…. Low survival limited the ability to examine for implicit learning. Nobody identified the visual image, 1/28(3.5%) identified the auditory stimulus. Despite marked cerebral ischemia (Mean rSO2=43%) normal EEG activity (delta, theta and alpha) consistent with consciousness emerged as long as 35-60 minutes into CPR.

- Key points on the target methodology:
The headphones were placed over the ears during CPR. One minute after being switched on, the tablet randomly projected one of 10 stored images onto its screen, and after five minutes (derived from implicit learning protocols during anesthesia) 6-10 audio cues (three fruits: apple-pear banana) were delivered to the headphones every minute for five minutes.

- One person identified the fruit (audio recall). Another had visual recollections of the ER scene, but could also feel things, so possibly CPRIC.
Key comment from discussion:
This is the first report of biomarkers of consciousness during CA/CPR.
Parnia et al Resuscitation (2023)
And:
Recent reports of a surge of gamma and other physiological electrical activity (ordinarily seen with lucid consciousness) during and after cardiac standstill and death, led to speculation that biomarker(s) of lucidity at death may exist [rat study and coma patients], which our findings support. Taken together, these studies and ours provide a novel understanding of how lucid experiences in relation to cardiac standstill/death may arise […] However, the paradoxical finding of lucidity and heightened reality when brain function is severely disordered, or has ceased raises the need to consider alternatives to the epiphenomenon theory [materialist].
Parnia et al Resuscitation (2023)
I don’t include anything from the data collected from subjects who were not part of the AWARE II clinical protocol, and who sent their subjective reports of NDEs to the lab. I don’t believe it belongs in this paper and potentially dilutes its very real scientific merit and is ultimately largely irrelevant to the key findings. [If anyone from the lab is reading this, I know that sounds snotty, it is just my subjective view, not intended as a criticism]
So there we have it, in conclusion:
- Due to the difficulties in recruiting only 28 patients were interviewed
- Of these 6 had NDEs (or REDs)
- The study didn’t have any visual hits (unsurprising given only 6 had NDEs)
- The audio hit was inconclusive
- EEG data “consistent with consciousness” was recorded in patients up to 60 minutes after CA began (although the majority of this EEG activity would not in fact be consistent with lucid consciousness)
So now for the big piece of news, probably the most important piece of data (for us here at least) that he presents, which is buried in the text underneath Figure 1 and the answer to the question I have been asking for 3.5 years and is the most relevant to this study – namely, did any of the patients who had NDEs/REDs have EEG data consistent with consciousness?
I had already guessed that there would be no data due to the difficulty in getting in interpretable EEG results, and I was right:
“Two of 28 interviewed subjects had EEG data, but weren’t among those with explicit cognitive recall”
Parnia et al Resuscitation (2023)
This is the money line. This is the one that shoots down any materialist attempts to use this study to say that NDEs are proven to be a result of brain activity (and there will be lots of attempts).
This is also where I dispute some elements of the discussion, particularly the “as an association doesn’t imply causation” statement, which I would normally agree with, but in this instance THERE IS NO ASSOCIATION. NONE. NADA. ZERO.
None of the subjects who reported conscious recollections, including the 6 who had NDEs had any EEG data, let alone EEG data that showed markers of consciousness. Let me repeat, because of this it is entirely false to say there is an association of brain activity with NDEs. This is no different from the findings from the rat studies or the coma patient studies. Speculation does not imply association!
FROM THIS STUDY AND ALL PREVIOUS STUDIES THERE ARE NO REPORTED NDEs THAT HAVE ANY EEG DATA, LET ALONE DATA SHOWING BRAIN ACTIVITY, ASSOCIATED WITH THESE REPORTS.
This means that we are back to square one. Despite the valiant efforts of Parnia and his team, we are no closer to having scientific evidence supporting any understanding of the cause of NDEs or the nature of consciousness. To say otherwise, especially without association, is pure speculation.
Look forward to the discussion, make sure you come back and check the comments.
Finally, I have had to pay for this paper and the upkeep of this blog, so would appreciate a tip if you have benefitted from reading this and not tipped before (or feel free to tip again if you are rich/and or generous 😊 )
