Scientific papers on hypnosis and brain injury

This is an attempt to make a complete up-to-date list of all literature pertaining to hypnosis and brain injury. I now consider the literature so big and dispersed that I feel quite confident that my list won’t be complete, but hopefully, it can get close. In each section, the most informative paper(s) are highlighted in green font.

This list contains many case-studies so there is likely a strong positive bias. I would advise reading the cases purely for methodological inspiration and look to the more systematic and comprehensive studies for an actual assessment of treatment effects.

I recommend reading the review by Appel (2003) as a start. It is a review on hypnosis for rehabilitation in general (not only brain injury) and is by far the most comprehensive review available so far, citing around half of the papers below.

As a side note, I was completely unaware of the scale of the literature when I undertook this search. The first version of this post contained around 10 papers and I considered it complete. One notable surprise is that the list of researchers now includes Milton Erickson and Aaron T. Beck in addition to John Kihlstrom.

Cognition

Status (April 2018): Completed.

Summary of the literature: There are (large) positive effects of hypnosis on cognition following acquired brain injury.

  • Cui-ping, L. I. (2011). Influence of hypnosis therapy on recovery of hemorrhagic stroke. Journal of Taishan Medical College, 1, 025. http://en.cnki.com.cn/Article_en/CJFDTOTAL-TSYX201101025.htm (see my English translation and comments)
    An RCT showing large effects (SMD = 1.0 to 1.7) on Barthel, anxiety, and depression in stroke patients given ten sessions of hypnosis between one and twelve weeks after the injury onset. The study is relatively large with 120 treatment-as-usual patients of which 49 had additional adjunctive hypnosis. It was published in Chinese in a Chinese journal with impact factor 0.1, and it is unclear whether it was peer-reviewed. In general, there are many reasons to be skeptical of the quality of this paper. Nonetheless, everything else being equal, it does increase the probability that hypnosis can improve cognition following acquired brain injury. With the help of Chinese friends, I got hold of the paper and helped reading it. I’ve added a link to my translation in the reference above, containing comments to clarify particular unclear sections and dubious statistics

    Our study, showing a large specific effect on working memory performance of hypnotic suggestions involving the return to pre-injury (or normal) functioning. It’s an RCT with a total of 68 patients stratified to targeted hypnosis, an active control, and a passive control. The effect of four and eight treatment sessions is assessed with long-term follow-up.
  • Milos, R. (1975). Hypnotic exploration of amnesia after cerebral injuries. International Journal of Clinical and Experimental Hypnosis23(2), 103–110. https://doi.org/10.1080/00207147508415934
    This paper is not really on cognitive rehabilitation but it does manage to (temporarily) get retrospective reports of experiences that were otherwise inaccessible due to retrograde or anterograde amnesia during hypnosis in 7 out of 20 cases of severe injury. It was not checked whether these reports were accurate, so this is prone to confabulations or changes in response criterions rather than a true cancellation of amnesia.
  • Sullivan, D. S., Johnson, A., & Bratkovitch, J. (1974). Reduction of behavioral deficit in organic brain damage by use of hypnosis. Journal of Clinical Psychology, 30(1), 96–98. https://doi.org/10.1002/1097-4679(197401)30:1<96::AID-JCLP2270300133>3.0.CO;2-A.
    Later we discovered this similar study had been carried out by Sullivan et al. (1974). The Sullivan study, however, had an intervention consisting of just seven sentences repeated twice – probably less than two minutes! They obtained a small positive effect on the Picture Completion task from the WAIS battery but not on the Binder-Gestalt test. They had a quite small sample, and the two-page article leaves many details unreported.

    A brief report on a 50-year case with cerebral hemorrhage, who underwent hypnosis when he was deemed chronic with severe symptoms. Hypnosis sparked further improvement. As a side note, the authors write that “To the best of our knowledge, this is the first study reporting on the integration of hypnosis as part of rehabilitation treatment of severe brain injury patients.” Well… 🙂

Motor disorders

Status (April, 2018): Approximately 70% completed. Needs a search for post-2000 literature, references, and citations

With the notable exception of Spankus & Freeman (1962) and Irawan et al. (2018), this literature consists largely of single-case studies, making it very vulnerable to publication bias. Confirming this, most studies report positive findings while Spankus & Freeman (1962) only report positive outcomes for four out of nineteen patients with cerebral palsy. Although somewhat disconcerting, this observation may not generalize to all of the literature given the large variability in the patient characteristics and treatment protocols between papers.

    This is an RCT on 2 x 16 stroke patients. Although the descriptive statistics seem convincing, there are some red flags. For example, the journal seems a bit dubious, there are spelling/grammatical mistakes, and half of the citations are non-English. More content-related, the statistics are relatively poor, lacking the test of the crucial 2 (pre/post) x 2 (treatment/control) interaction term, which would be identical to the independent t-test on the change scores in each group. It does look like such a test would come out significant with a test would come out positive given the large improvement in the treatment group (d = 1) as compared to the control group (d = 0.1).

An unknown journal, major grammatical errors (bordering on not being comprehensible), and major omissions in the reporting. Still, it’s a controlled study with 44 hemmorrhagic stroke patients, so it has larger weight than many other studies on this list. Says that “No publication of research like this before” which is obviously false, as is apparent from this list.

    This is an RCT with a treatment group, an active control group (discussion groups) and a treatment-as-usual group. The participants were recruited from care homes and had vascular dementia (acquired brain injury) or dementia (unspecified…), and a few Parkinson’s patients. The intervention was quite extensive with 36 weekly sessions of hypnosis or discussion and a 12-month follow-up after that. The outcome was a questionnaire-only assessment of Quality of Life with large effects on all aspects which were all maintained after 12 months, except for relaxation. The small sample size and the subjective nature of the report are reasons to be cautious, but otherwise, it’s some of the most informative data on hypnosis for dementias to date (2018).

Pain, vertigo, anxiety (in progress)

Status (April, 2018): Approximately 40% completed. Needs a systematic search, reference search, and citation search.

This is a catch-all category for directly unpleasant sequelae following acquired brain injury. Sullivan et al. (1974) hypothesized that they relieved anxiety. But they never directly assessed anxiety, so I presented it on the list for cognitive rehabilitation. Fromm (1964) and Gruenewald & Fromm (1967) tried to induce catastrophic anxiety in healthy subjects.

  • Cedercreutz, C., Lähteenmäki, R., & Tulikoura, J. (1976). Hypnotic treatment of headache and vertigo in skull injured patients. International Journal of Clinical and Experimental Hypnosis, 24(3–4), 195–201. https://doi.org/10.1080/00207147608416201
    This paper summarizes clinical results of 155 patients with pain and/or vertigo sequelae. So this is a large portion of evidence as compared to the rest of this list. As with the other case studies, it may be prone to experimenter bias. The reported effects are quite impressive in a median of three-to-four sessions to achieve complete symptom relief in more than half of the patients.

    A case of hemiparesis, aphasia, and hyperalgesia following some vascular anomalities. This is Milton Erickson! After 11-months of no progress, Erickson takes on therapy in (at least) five months. There was great progress in this time, though it is not self-evident that this can be attributed to the intervention given the extensive duration of the intervention. His strategy relies heavily on frustrating the patient including lying, overruling, deceiving, etc. in front of others. I personally find his approach appalling. There is very little formal hypnosis in this paper.

    Epilepsy following acquired brain injury. Hypnosis was employed in two cases to reveal painful emotional memories connected to the aura. Yes, Aaron T. Beck, the father of cognitive behavioral therapy (CBT) did a study on hypnosis and acquired brain injury!

    Simply shows the result of a survey, that 5.1 % (around 7 out of 165) of therapists use hypnotherapy for post-concussion patients. This is the only mention of hypnosis in the article.

Brain injury “models” in non-injured humans

Status (April 2018): Probably completed. But needs systematic search, reference search, citation search.

Take-home: healthy subjects can be hypnotized to play the role of brain-injured patients, but they are probably not realistic brain-injury models.

    Hypnotized subjects (n=9) to believed that they had sustained an organic brain injury. After “hypnotic brain injury,” the subjects who experienced being in deep hypnosis were judged to be more “organic” by blinded neuropsychologists than under “hysterical” and no-hypnosis conditions, in which they were judged to be non-injured. The results from this study failed to replicate in a methodologically superior follow-up in Gruenwald & Fromm (1967).

    Replication of Fromm et al. (1964) with an improved method, controlling for more potential confounders. There were no difference between the hypnosis and control group judgment, actual score, or subjective experience.

    Like Fromm (1964), but adds malingering-detection tests to the test battery, showing that “hypnotically brain injured” healthy subjects indeed do act as malingerers, not as real brain-injured patients.

Search strategy and current status of this list

Google Scholar was searched using the term “hypnosis OR “hypnotic suggestion” brain-injury OR brain-damage OR stroke OR hemiplegia OR paraplegia OR “traumatic brain” OR “diffuse axonal” OR hemorrhage”. The reference list of all hits for which I had access to full texts were scanned. For some papers, the list of papers citing that paper were scanned too, using Google Scholar.

Next steps (my to do):

  • Read Appel (2003) thoroughly again for more keywords to search on.
  • Make a histogram of publication years relative to general science publication volume.
  • Do searches on post-concussion syndrome?
  • Dementias? start with this Duff search.

Identified papers that I need to screen/comment:

  • Look into https://www.amazon.com/Clinical-Experimental-Hypnosis-Dentistry-Psychology-ebook/dp/B01MXFB423. Apparently contains something on hypnosis and brain injury
  • https://www.frontiersin.org/articles/10.3389/fpsyg.2012.00465/full
  • Appel PR: Performance enhancement in physical medicine and rehabilitation. Am J Clin Hypn 35:11-19, 1992
