Combining Cognitive-Behavioral Conjoint Therapy for PTSD with 3,4-Methylenedioxymethamphetamine (MDMA): A Case Example.

March 19, 2019 / Anxiety Disorders / PTSD, MDMA, Papers, Psychology, Publications / By / , , ,

Abstract

Treatments for posttraumatic stress disorder (PTSD) have evolved significantly in the past 35 years. From what was historically viewed as a pervasive, intractable condition have emerged multiple evidence-based intervention options. These treatments, predominantly cognitive behavioral in orientation, provide significant symptom improvement in 50-60% of recipients. The treatment of PTSD with MDMA-assisted psychotherapy using a supportive, non-directive approach has yielded promising results. It is unknown, however, how different therapeutic modalities could impact or improve outcomes. Therefore, to capitalize on the strengths of both approaches, Cognitive Behavioral Conjoint Therapy for PTSD (CBCT) was combined with MDMA in a small pilot trial. The current article provides a case study of one couple involved in the trial, chosen to provide a demographically representative example of the study participants and a case with a severe trauma history, to offer a detailed account of the methodology and choices made to integrate CBCT and MDMA, as well as an account of their experience through the treatment and their treatment gains. This article offers a description of the combination of CBCT for PTSD and MDMA, and demonstrates that it can produce reductions in PTSD symptoms and improvements in relationship satisfaction.

Beyond LSD: A Broader Psychedelic Zeitgeist during the Early to Mid-20 th Century

March 6, 2019 / Humanities & Art, LSD, Mescaline / Cacti, Mushrooms / Psilocybin, Papers, Psychology, Publications / By / , ,

Abstract

During the 1950s and 1960s, there was a tremendous surge in research into the effects of psychedelic drugs. When discussing this period of research, the discovery of the psychoactive properties of LSD in 1943 is often presented as the main, and sometimes only, driving force of the boom in research. This “Great Person,” or “Great Chemical,” historiographical lens fails to acknowledge other factors that were fundamental in setting the stage for the research. In particular, other psychedelic drugs, such as mescaline, were already being probed for their uses in psychotherapy and as models for psychosis before the effects of LSD had been discovered. Psilocybin and other classical psychedelics had also been discovered by Western researchers around the same time as the synthesis of LSD. Additionally, many of the dominant zeitgeists (e.g., pharmacological, psychoanalytic, and humanistic) in psychology during this period were congruent with psychedelic research. This article argues that while the discovery of LSD may have been a catalyst for psychedelic research in the 1950s and ’60s, there was a broader psychedelic zeitgeist that deserves acknowledgement for setting the stage.

Ketamine: A Paradigm Shift for Depression Research and Treatment

March 6, 2019 / Depressive Disorders, Papers, Psychology, Publications / By / , , , ,

Abstract

Ketamine is the first exemplar of a rapid-acting antidepressant with efficacy for treatment-resistant symptoms of mood disorders. Its discovery emerged from a reconceptualization of the biology of depression. Neurobiological insights into ketamine efficacy shed new light on the mechanisms underlying antidepressant efficacy.

Ibogaine Administration Modifies GDNF and BDNF Expression in Brain Regions Involved in Mesocorticolimbic and Nigral Dopaminergic Circuits.

March 5, 2019 / Iboga / Ibogaine, Neuroscience, Papers, Psychology, Publications, Substance Use Disorder / By / , , , , , ,

Abstract

Ibogaine is an atypical psychedelic alkaloid, which has been subject of research due to its reported ability to attenuate drug-seeking behavior. Recent work has suggested that ibogaine effects on alcohol self-administration in rats are related to the release of Glial cell Derived Neurotrophic Factor (GDNF) in the Ventral Tegmental Area (VTA), a mesencephalic region which hosts the soma of dopaminergic neurons. Although previous reports have shown ibogaine’s ability to induce GDNF expression in rat midbrain, there are no studies addressing its effect on the expression of GDNF and other neurotrophic factors (NFs) such as Brain Derived Neurotrophic Factor (BDNF) or Nerve Growth Factor (NGF) in distinct brain regions containing dopaminergic neurons. In this work, we examined the effect of ibogaine acute administration on the expression of these NFs in the VTA, Prefrontal Cortex (PFC), Nucleus Accumbens (NAcc) and the Substantia Nigra (SN). Rats were i.p. treated with ibogaine 20 mg/kg (I20), 40 mg/kg (I40) or vehicle, and NFs expression was analyzed after 3 and 24 h. At 24 h an increase of the expression of the NFs transcripts was observed in a site and dose dependent manner. Only for I40, GDNF was selectively upregulated in the VTA and SN. Both doses elicited a large increase in the expression of BDNF transcripts in the NAcc, SN and PFC, while in the VTA a significant effect was found only for I40. Finally, NGF mRNA was upregulated in all regions after I40, while I20 showed a selective upregulation in PFC and VTA. Regarding protein levels, an increase of GDNF was observed in the VTA only for I40 but no significant increase for BDNF was found in all the studied areas. Interestingly, an increase of proBDNF was detected in the NAcc for both doses. These results show for the first time a selective increase of GDNF specifically in the VTA for I40 but not for I20 after 24 h of administration, which agrees with the effective dose found in previous self-administration studies in rodents. Further research is needed to understand the contribution of these changes to ibogaine’s ability to attenuate drug-seeking behavior.

Chronic, Intermittent Microdoses of the Psychedelic N,N-Dimethyltryptamine (DMT) Produce Positive Effects on Mood and Anxiety in Rodents

March 4, 2019 / Anxiety Disorders / PTSD, Depressive Disorders, DMT, Papers, Psychology, Publications / By / , , , ,

Abstract

Drugs capable of ameliorating symptoms of depression and anxiety while also improving cognitive function and sociability are highly desirable. Anecdotal reports have suggested that serotonergic psychedelics administered in low doses on a chronic, intermittent schedule, so-called “microdosing”, might produce beneficial effects on mood, anxiety, cognition, and social interaction. Here, we test this hypothesis by subjecting male and female Sprague Dawley rats to behavioral testing following the chronic, intermittent administration of low doses of the psychedelic N,N-dimethyltryptamine (DMT). The behavioral and cellular effects of this dosing regimen were distinct from those induced following a single high dose of the drug. We found that chronic, intermittent, low doses of DMT produced an antidepressant-like phenotype and enhanced fear extinction learning without impacting working memory or social interaction. Additionally, male rats treated with DMT on this schedule gained a significant amount of body weight during the course of the study. Taken together, our results suggest that psychedelic microdosing may alleviate symptoms of mood and anxiety disorders, though the potential hazards of this practice warrant further investigation.

5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) used in a naturalistic group setting is associated with unintended improvements in depression and anxiety

March 1, 2019 / Anxiety Disorders / PTSD, Depressive Disorders, DMT, Neuroscience, Papers, Psychiatry & Medicine, Psychology, Publications / By / , , , ,

Abstract

BACKGROUND:

A recent epidemiological study suggested that 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) used for spiritual and recreational reasons is associated with subjective improvement in depression and anxiety. Further exploration of the potential psychotherapeutic effects of 5-MeO-DMT could inform future clinical trials.

OBJECTIVES:

We examined self-reported improvement in depression and anxiety among people who use 5-MeO-DMT in a group setting with structured procedures guiding dose and administration of 5-MeO-DMT. Such procedures also include activities for the preparation of, and support during/following sessions, which are similar to procedures used in clinical trials of hallucinogen administration. Next, we examined whether depression or anxiety were improved following use, and whether the acute subjective effects (mystical/challenging) or beliefs about the 5-MeO-DMT experience were associated with improvements in these conditions.

METHODS:

Respondents (n = 362; Mage = 47.7; Male = 55%; White/Caucasian = 84%) completed an anonymous web-based survey.

RESULTS:

Of those reporting having been diagnosed with depression (41%) or anxiety (48%), most reported these conditions were improved (depression = 80%; anxiety = 79%) following 5-MeO-DMT use, and fewer reported they were unchanged (depression = 17%; anxiety = 19%) or worsened (depression = 3%; anxiety = 2%). Improvement in depression/anxiety conditions were associated with greater intensity of mystical experiences and higher ratings of the spiritual significance and personal meaning of the 5-MeO-DMT experience. There were no associations between depression or anxiety improvement and the intensity of acute challenging physical/psychological effects during the 5-MeO-DMT experience.

CONCLUSIONS:

Future prospective controlled clinical pharmacology studies should examine the safety and efficacy of 5-MeO-DMT administration for relieving depression and anxiety.

Psychedelics and Dying Care: A Historical Look at the Relationship between Psychedelics and Palliative Care.

March 1, 2019 / Anxiety Disorders / PTSD, LSD, Papers, Psychology, Publications / By /

Abstract

This article examines the historical relationship between psychedelics and palliative care. Historians have contributed to a growing field of studies about how psychedelics have been used in the past, but much of that scholarship focused on interrogating questions of legitimacy or proving that psychedelics had therapeutic potential. Palliative care had not yet developed as medical sub-specialty, more often leaving dying care on the margins of modern, pharmaceutical-based treatments. As psychedelic researchers in the 1950s began exploring different applications for psychoactive substances such as LSD and mescaline, however, dying care came into clearer focus as a potential avenue for psychedelics. Before that application gained momentum in clinical or philosophical discussions, psychedelics were criminalized and some of those early discussions were lost. This article looks back at historical discussions about LSD’s potential for easing the anxiety associated with dying, and considers how those early conversations might offer insights into today’s more articulated discussions about psychedelics in palliative care.

Recreational use of psychedelics is associated with elevated personality trait openness: Exploration of associations with brain serotonin markers

February 28, 2019 / MDMA, Neuroscience, Papers, Psychology, Publications / By / , , , ,

Abstract

BACKGROUND:

Recent studies have suggested therapeutic benefits of psychedelics for a variety of mental health conditions. The understanding of how single psychedelic administrations can induce long-lasting effects are, in large, still lacking. However, recent studies in both healthy and clinical populations suggest a role for personality changes.

AIM:

To test support for some of these plausible mechanisms we evaluated (cross-sectional) associations between recreational use of psychedelics and 3,4-methylene-dioxymethamphetamine (MDMA) and (a) personality measures and (b) key markers of cerebral serotonergic signalling (serotonin transporter and serotonin-2A-receptor binding).

METHODS:

In 10 psychedelic-preferring recreational users, 14 MDMA-preferring users and 21 non-using controls, personality was assessed using the ‘big five’ instrument Revised NEO Personality Inventory (NEO-PI-R). Frontal serotonin transporter and serotonin-2A-receptor binding potentials were quantified using [11C]DASB and [18F]altanserin positron emission tomography, respectively.

RESULTS:

Of the five NEO-PI-R traits, only openness to experience scores differed between the three groups; psychedelic-preferring recreational users showing higher openness to experience scores when compared with both MDMA-preferring users and controls. Openness to experience scores were positively associated with lifetime number of psychedelic exposures, and among all MDMA-preferring user/psychedelic-preferring recreational user individuals, frontal serotonin transporter binding – but not frontal serotonin-2A-receptor binding – was positively associated with openness to experience.

CONCLUSION:

Our findings from this cross-sectional study support increasing evidence of a positive association between psychedelic experiences and openness to experience, and (a) expands this to the context of ‘recreational’ psychedelics use, and (b) links serotonergic neurotransmission to openness to experience. A modulation of personality induced by psychedelic experiences may have important therapeutic implications via its impact on peoples’ value systems, cognitive flexibility, and individual and social behaviour.

Sub-Acute Effects of Psilocybin on Empathy, Creative Thinking, and Subjective Well-Being

February 28, 2019 / Depressive Disorders, Mushrooms / Psilocybin, Neuroscience, Papers, Psychology / By / , , ,

Abstract

Creative thinking and empathy are crucial for everyday interactions and subjective well-being. This is emphasized by studies showing a reduction in these skills in populations where social interaction and subjective well-being are significantly compromised (e.g., depression). Anecdotal reports and recent studies suggest that a single administration of psilocybin can enhance such processes and could therefore be a potential treatment. However, it has yet to be assessed whether effects outlast acute intoxication. The present study aimed to assess the sub-acute effects of psilocybin on creative thinking, empathy, and well-being. Participants attending a psilocybin retreat completed tests of creative (convergent and divergent) thinking and empathy, and the satisfaction with life scale on three occasions: before ingesting psilocybin (N = 55), the morning after (N = 50), and seven days after (N = 22). Results indicated that psilocybin enhanced divergent thinking and emotional empathy the morning after use. Enhancements in convergent thinking, valence-specific emotional empathy, and well-being persisted seven days after use. Sub-acute changes in empathy correlated with changes in well-being. The study demonstrates that a single administration of psilocybin in a social setting may be associated with sub-acute enhancement of creative thinking, empathy, and subjective well-being. Future research should test whether these effects contribute to the therapeutic effects in clinical populations.
