Abstract

Posttraumatic stress disorder (PTSD) is often a chronic condition, despite the availability of various evidence-based treatment options. Psychedelics offer new treatment opportunities.<br/> AIM: An overview of the current evidence, therapeutic context, and possible mechanisms of action of different types of psychedelics in the treatment of PTSD.<br/> METHOD: A scoping review of the available literature.<br/> RESULTS: MDMA-assisted psychotherapy has shown to produce lasting reductions in PTSD symptoms in multiple RCTs. Based on a small number of studies, ketamine administration appears to lead to temporary symptom relief. Current studies are investigating whether the use of ketamine in combination with psychotherapy can lead to lasting reductions in PTSD symptoms. Classical psychedelics (such as psilocybin and LSD) induce psychoactive effects (on behavior or experience) that could contribute to the psychotherapeutic treatment of PTSD but have not yet been investigated in controlled studies. Reported positive effects extend beyond PTSD symptoms only.<br/> CONCLUSION: Psychedelics may have potential to serve as a catalyst for the psychotherapeutic treatment of PTSD. Most evidence exists for MDMA-supported psychotherapy; relatively little research is available on ketamine and classical psychedelics. Future research needs to show whether the use of psychedelics can be integrated into available treatment options for PTSD.

3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy for victims of sexual abuse with severe post-traumatic stress disorder: an open label pilot study in Brazil

July 3, 2020 / Anxiety disorders / PTSD, MDMA, Medicine, Papers, Psychiatry, Psychology, Psychopharmacology, Psychotherapy, Publications / By / , , , , , ,

Abstract

Objective: To conduct Brazil’s first clinical trial employing 3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy for post-traumatic stress disorder (PTSD), given its high prevalence resulting from epidemic violence.

Methods: Of 60 volunteers, four matched the inclusion & exclusion criteria. Three patients with PTSD secondary to sexual abuse (diagnosed by the Structured Clinical Interview for DSM-IV and the Clinician Administered PTSD Scale for DSMV-4 [CAPS 4]) completed enrollment and treatment, following a standardized Multidisciplinary Association for Psychedelic Studies protocol consisting of 15 weekly therapy sessions: three with orally administered MDMA with concurrent psychotherapy and music, spaced approximately 1 month apart. CAPS-4 scores two months after the final MDMA session were the primary outcome.

Results: No serious adverse events occurred. The most frequent adverse events were somatic pains and anguish. CAPS-4 reductions were always greater than 25 points. The final scores were 61, 27, and 8, down from baseline scores of 90, 78, and 72, respectively. All reductions were greater than 30%, which is indicative of clinically significant improvement. Secondary outcomes included lower Beck Depressive Inventory scores and higher Post-Traumatic Growth Inventory and Global Assessment of Functioning scores.

Conclusions: Considering the current limitations in safe and efficacious treatments for PTSD and recent studies abroad with larger patient samples, MDMA-assisted psychotherapy could become a viable treatment in Brazil.

The Effects of 3,4-methylenedioxymethamphetamine on Neurogenesis in the Hippocampus of Male Rats

February 6, 2022 / MDMA, Neuroscience, Papers / Leave a Comment / By / , , , , , ,

Abstract

Introduction: The administration of 3,4-methylenedioxymethamphetamine (MDMA) or ecstasy causes memory impairment, whereas neurogenesis improves memory and learning. Hence, this study evaluated the effects of MDMA on neurogenesis in the hippocampus of male rats.

Methods: Adult male Wistar rats received Intraperitoneal (IP) injections of MDMA (10 mg/ kg). We assessed nestin, sex-determining region Y-box 2 (Sox2), and NeuroD expressions according to the immunohistochemistry analyses.

Results: MDMA reduced the expressions of nestin, Sox2, and NeuroD compared with the control groups. The reduction in NeuroD expression was age-related.

Conclusion: MDMA possibly has negative effects on neurogenesis, which specifically results from impaired survival of newborn cells.

Integrating psychotherapy and psychopharmacology: psychedelic-assisted psychotherapy and other combined treatments

June 12, 2020 / Depression, History, MDMA, Other subjects, Papers, Psychology, Psychopharmacology, Psychotherapy, Publications / By / , , ,

Abstract

Introduction: Combinations of psychotherapy with antidepressants are gold-standard psychiatric treatments. They operate through complex and interactional mechanisms, not unlike the reemergent paradigm of psychedelic-assisted psychotherapy, which promising research suggests may also be highly effective in even challenging populations.
Areas covered: We review the therapeutic mechanisms behind both conventional and psychedelic paradigms, including the evolution of this knowledge and the associated explanatory frameworks. We explore how psychedelics have provided insights about psychiatric illnesses and treatments over the past decades. We discuss limitations to early explanatory models while highlighting and comparing the psychological and biological mechanisms underlying many psychiatric treatments.
Methods: A narrative review was conducted based on a search in Medline/Pubmed up to January 1st, 2020, and iterative retrieval of references from recent reviews and clinical trials.
Expert opinion: The contextual model of the common factors of psychotherapy provides a powerful perspective on psychotherapy, antidepressants, and psychedelics, as well as 3,4-methylenedioxymethamphetamine (MDMA) and ketamine. It aligns well with key tenets of psychedelic-assisted psychotherapy. Conventional antidepressants and especially psychedelics may improve the efficacy of psychotherapy via neurochemical changes and increased environmental sensitivity. Combined treatments hold significant promise for advancing the knowledge and treatment of many forms of psychopathology.

Spotlight commentary: REBUS and the anarchic brain

Abstract

In ‘REBUS and the Anarchic Brain: Towards a Unified Model of the Brain Action of Psychedelics’, Carhart-Harris and Friston offer an important analysis of what the predictive processing framework has to offer our understanding of psychedelic experiences, providing an invaluable ground for psychedelic psychiatry. While applauding this, we encourage paying greater attention to contextual factors shaping extreme experiences and their sequalae, and suggest that the authors’ comparisons with certain non-psychedelic altered states may overlook more informative parallels that can be drawn elsewhere. Addressing both points will prove fruitful, ultimately, in identifying the mechanisms of action of greatest interest in psychedelic experiences.

A Meta-Analysis of Placebo-Controlled Trials of Psychedelic-Assisted Therapy

June 12, 2020 / Ayahuasca, DMT, MDMA, Mushrooms / Psilocybin, Papers, Psychiatry, Psychology, Psychopharmacology, Publications / By / , , , ,

Abstract

After a two-decade hiatus in which research on psychedelics was essentially halted, placebo-controlled clinical trials of psychedelic-assisted therapy for mental health conditions have begun to be published. We identified nine randomized, placebo-controlled clinical trials of psychedelic-assisted therapy published since 1994. Studies examined psilocybin, LSD (lysergic acid diethylamide), ayahuasca (which contains a combination of N,N-dimethyltryptamine and harmala monoamine oxidase inhibitor alkaloids), and MDMA (3,4-methylenedioxymethamphetamine). We compared the standardized mean difference between the experimental and placebo control group at the primary endpoint. Results indicated a significant mean between-groups effect size of 1.21 (Hedges g), which is larger than the typical effect size found in trials of psychopharmacological or psychotherapy interventions. For the three studies that maintained a placebo control through a follow-up assessment, effects were generally maintained at follow-up. Overall, analyses support the efficacy of psychedelic-assisted therapy across four mental health conditions – post-traumatic stress disorder, anxiety/depression associated with a life-threatening illness, unipolar depression, and social anxiety among autistic adults. While study quality was high, we identify several areas for improvement regarding the conduct and reporting of trials. Larger trials with more diverse samples are needed to examine possible moderators and mediators of effects, and to establish whether effects are maintained over time.

Mystical Experiences in Retrospective Reports of First Times Using a Psychedelic in Finland

June 8, 2020 / Ayahuasca, Cacti / Mescaline, DMT, Iboga / Ibogaine, Ketamine, LSD, MDMA, Mushrooms / Psilocybin, Mystical experiences, Other substances, Papers, Psychiatry, Psychology, Psychopharmacology, Publications, Salvia / Salvinorin A / By / , ,

Abstract

Despite their acutely inebriating and sometimes unpleasant effects, some people report positive changes in life satisfaction, well-being, or mental health after taking psychedelic drugs. One explanation may be the ability of psychedelics to trigger mystical-type experiences. We examined the validity, reliability, and factor structure of a novel Finnish translation of the Revised Mystical Experiences Questionnaire (MEQ30) among 288 people retrospectively reporting on their first time using a psychedelic. We found evidence for internal consistency reliability and preliminary evidence for criterion and discriminant validity of the Finnish MEQ30. A four-factor structure with factors for mystical qualities, positive mood, transcendence, and ineffability had the best, fair to reasonable fit to the data. MEQ30 scores and having a full mystical experience were highly associated with describing the experience as mystical, spiritual, or religious, and as personally significant, and somewhat associated with the experience being sad or difficult. Mystical experiences were especially associated with positive changes in relationships with nature and oneself and in creativity. Mystical experiences were more common with larger doses. Increasing research suggests mystical-type experiences to relate to positive changes after taking psychedelics. The Finnish MEQ30 is able to tap into relevant information about this aspect of people’s psychedelic experiences.

Long-term follow-up outcomes of MDMA-assisted psychotherapy for treatment of PTSD: a longitudinal pooled analysis of six phase 2 trials

January 3, 2022 / Anxiety disorders / PTSD, MDMA, Papers, Psychiatry, Psychotherapy / Leave a Comment / By / , , , , , , ,

Abstract

Rationale: Posttraumatic stress disorder (PTSD) is a chronic condition that has wide-ranging negative effects on an individual’s health and interpersonal relationships. Treatments with long-term benefits are needed to promote the safety and well-being of those suffering from PTSD.

Objectives: To examine long-term change in PTSD symptoms and additional benefits/harms after 3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy for treatment of PTSD.

Methods: Participants received two to three active doses of MDMA (75-125 mg) during blinded or open-label psychotherapy sessions with additional non-drug therapy sessions. PTSD symptoms were assessed using the Clinician-Administered PTSD Scale for DSM IV (CAPS-IV) at baseline, 1 to 2 months after the last active MDMA session (treatment exit), and at least 12 months post final MDMA session (LTFU). A mixed-effect repeated-measures (MMRM) analysis assessed changes in CAPS-IV total severity scores. The number of participants who met PTSD diagnostic criteria was summarized at each time point. Participants completed a long-term follow-up questionnaire.

Results: There was a significant reduction in CAPS-IV total severity scores from baseline to treatment exit (LS mean (SE) = – 44.8 (2.82), p < .0001), with a Cohen’s d effect size of 1.58 (95% CI = 1.24, 1.91). CAPS-IV scores continued to decrease from treatment exit to LTFU (LS mean (SE) = – 5.2 (2.29), p < .05), with a Cohen’s d effect size of 0.23 (95% CI = 0.04, 0.43). The number of participants who no longer met PTSD criteria increased from treatment exit (56.0%) to LTFU (67.0%). The majority of participants reported benefits, including improved relationships and well-being, and a minority reported harms from study participation.

Conclusions: PTSD symptoms were reduced 1 to 2 months after MDMA-assisted psychotherapy, and symptom improvement continued at least 12 months post-treatment. Phase 3 trials are investigating this novel treatment approach in a larger sample of participants with chronic PTSD.

MDMA-assisted psychotherapy for people diagnosed with treatment-resistant PTSD: what it is and what it isn’t

May 12, 2020 / Anxiety disorders / PTSD, MDMA, Papers, Psychiatry, Psychology, Psychopharmacology, Publications / By /

Abstract

Background

PTSD is a chronic condition with high rates of comorbidity, but current treatment options are limited and not always effective. One novel approach is MDMA-assisted psychotherapy for people diagnosed with treatment-resistant PTSD, where MDMA is used as a catalyst to facilitate trauma processing during psychotherapy. The aim was to review all current research into MDMA-assisted psychotherapy for PTSD.

Methods

Articles were identified through PubMed and Science Direct for items published up to 31st March 2019 using terms “treatments for PTSD”, “drug treatments for PTSD”, “MDMA”, “MDMA pathway”, “MDMA-assisted psychotherapy” and “MDMA-assisted psychotherapy for PTSD”. Articles were identified through Google Scholar and subject-specific websites. Articles and relevant references cited in those articles were reviewed.

Results

Small-scale studies have shown reduced psychological trauma, however there has been widespread misunderstanding of the aims and implications of this work, most commonly the notion that MDMA is a ‘treatment for PTSD’, which to date has not been researched. This has harmful consequences, namely dangerous media reporting and impeding research progression in an already controversial field.

Conclusions

MDMA-assisted psychotherapy may help people who have experienced psychological trauma and who have not been able to resolve their problems through existing treatments, however more research is needed. If this is to get appropriate research attention, we must report this accurately and objectively.
