August 1, 2020 / Anxiety Disorders / PTSD, Depressive Disorders, Ketamine, Papers, Psychology, Psychotic Disorders, Publications, Substance Use Disorder / By / , , ,

Abstract

After psychedelics were banned in 1968, the flourishing research on the use of psychedelics in patients with a mental disorder stopped abruptly. Recently, we see a renaissance of this research.<br/> AIM: To present an overview of what is known about the treatment of addiction and psychosis with psychedelics.<br/> METHOD: Literature study based on Medline en PubMed publications till December 2019.<br/> RESULTS: Studies on the effectiveness of psychedelics in the treatment of addiction and psychosis is still very limited in size and methodological quality. Nevertheless, most studies show positive effects of both classical and atypical psychedelics in a variety of addictions on motivation, craving, reduced consumption, and abstinence often following a single dose and with long-lasting benefits (3-24 months). Use of ketamine in patients with a psychosis stabilized on an antipsychotic might reduce negative symptoms.<br/> CONCLUSION: Before psychedelics can be used in standard clinical practice for the treatment of patients with an addiction or a psychosis, larger and methodologically better studies are needed. The use of psychedelics also creates an opportunity to better understand the shared underlying pathology of many different mental disorders.

Abstract

Existential distress in patients with a terminal illness is often associated with (symptoms of) anxiety and depression. Psychotherapeutic interventions seem effective but effects are short-lived. There are no proven effective pharmacological interventions.<br/> AIM: To present an overview of literature on psychedelic treatment of existential distress in patients with terminal illness.<br/> METHOD: Literature research in PubMed/Medline databases, supplemented with cross-references.<br/> RESULTS: 14 clinical studies have been conducted: 6 with classic psychedelics between 1960 and 1980, and 8 with classic psychedelics and ketamine after 2000. Results of early pre-post studies are promising but have serious methodological limitations. Recent clinical research with LSD, psilocybin and ketamine are also promising although limited in terms of research design and generalizability. Overall, studies show a positive effect on existential and spiritual well-being, quality of life, acceptance and (symptoms of) anxiety and depression. Mystical experiences are correlated with positive outcomes. Few adverse effects are reported.<br/> CONCLUSION: Treatment of existential distress using classical psychedelics or ketamine in patients with terminal illness seems auspicious. Larger clinical studies in a more diverse patient population with fewer methodological limitations are needed to draw conclusions about efficacy and generalizability.

[Psychedelics in the treatment of PTSD]

August 1, 2020 / Anxiety Disorders / PTSD, Depressive Disorders, Ketamine, LSD, MDMA, Papers, Psychology, Publications / By / , , , , ,

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.

Psychedelic Treatment for Trauma-Related Psychological and Cognitive Impairment Among US Special Operations Forces Veterans

July 8, 2020 / Anxiety Disorders / PTSD, Depressive Disorders, DMT, Iboga / Ibogaine, Neuroscience, Papers, Psychiatry & Medicine, Psychology, Psychotic Disorders, Publications / By / , , , ,

Abstract

Background

U.S. Special Operations Forces Veterans are at increased risk for a variety of mental health problems and cognitive impairment associated with military service. Current treatments are lacking in effectiveness and adherence. Therefore, this study examined psychedelic treatment with ibogaine and 5-methoxy-N,N-dimethyltryptamine for trauma-related psychological and cognitive impairment among U.S. Special Operations Forces Veterans.

Method

We conducted a survey of Veterans who completed a specific psychedelic clinical program in Mexico between 2017 and 2019. Questions probed retrospective reports of mental health and cognitive functioning during the 30 days before and 30 days after treatment. A total of 65 people completed treatment during this time frame and were eligible for contact. Of these, 51 (78%) completed the survey and were included in data analyses (mean age = 40; male = 96%; married = 55%; Caucasian/White = 92%; Operation Enduring Freedom/Operation Iraqi Freedom Service = 96%).

Results

Results indicated significant and very large reductions in retrospective report of suicidal ideation (p < .001; d = −1.9), cognitive impairment (p < .001; d = −2.8), and symptoms of posttraumatic stress disorder (p < .001; d = −3.6), depression (p < .001; d = −3.7), and anxiety (p < .001; d = −3.1). Results also showed a significant and large increase in retrospective report of psychological flexibility (p < .001; d = 2.9) from before-to-after the psychedelic treatment. Increases in the retrospective report of psychological flexibility were strongly associated with retrospective report of reductions in cognitive impairment, and symptoms of posttraumatic stress disorder, depression, and anxiety (rs range −0.61 to −0.75; p < .001). Additionally, most participants rated the psychedelic experiences as one of the top five personally meaningful (84%), spiritually significant (88%), and psychologically insightful (86%) experiences of their lives.
Limitations: Several limitations should be considered including the retrospective, self-report, survey design of the study, and the lack of randomization and blinding, thus making these finding preliminary.

Conclusion

U.S. Special Operations Forces Veterans may have unique treatment needs because of the sequela of problems associated with repeated trauma exposure and the nature of the exposure. Psychedelic-assisted therapy with these under-researched psychedelics may hold unique promise for this population. However, controlled studies are needed to determine whether this treatment is efficacious in relieving mental health and cognitive impairment among U.S. Special Operations Forces Veterans.

Historic psychedelic drug trials and the treatment of anxiety disorders

December 6, 2021 / Anxiety Disorders / PTSD, Papers, Psychiatry & Medicine, Psychology, Publications / By / , , , , , ,

Abstract

Introduction: In this paper, we systematically review literature from 1940 to 2000 relating to the combined use of psychological therapies and psychedelic drugs in the treatment of ICD-10 anxiety disorders.

Methods: The databases Ovid MEDLINE(R), PsycINFO, and Multidisciplinary Association for Psychedelic Studies (MAPS) were searched for case reports and trials involving humans in the treatment of ICD-10 anxiety and related disorders. Twenty-four studies are described; four describe anxiety symptoms in diverse patient groups, 14 studies describe historic diagnoses that usefully correspond with ICD-10 anxiety disorders, six studies pooled results or failed to detail results specific to contemporary ICD-10 anxiety disorders. Two of the 24 studies reported are individual case reports while two of them were inadequate in terms of the reporting of outcome measures. Thus 20 studies were ultimately included in the summary analysis.

Results: Three of the 20 studies reviewed described improvements in anxiety by standardized measures (p < .05) and two studies found that this effect was dose related. Of the 20 studies included in the final analysis, 94 of 145 (65%) cases of “psychoneurotic anxiety reaction” as defined by Diagnostic and Statistical Manual of Mental Disorders-I showed improvement that ranged from moderate improvement to full recovery. Despite methodological inadequacies, the results from previous studies are encouraging and should be used to guide and inform further investigation.

Conclusion: The majority of studies indicate that a combination of psychedelic drug administration and psychological therapy was most beneficial. We found no study suggesting that the pharmacological action of psychedelic drugs in isolation is sufficient.

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, Papers, Psychiatry & Medicine, Psychology, 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.

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 / 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, Psychology, 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.

Psilocybin: from ancient magic to modern medicine

May 12, 2020 / Anthropology & Sociology, Anxiety Disorders / PTSD, Biology & Ethnobotany, Depressive Disorders, Humanities & Art, Mushrooms / Psilocybin, Papers, Psychology, Publications / By /

Abstract

Psilocybin (4-phosphoryloxy-N,N-dimethyltryptamine) is an indole-based secondary metabolite produced by numerous species of mushrooms. South American Aztec Indians referred to them as teonanacatl, meaning “god’s flesh,” and they were used in religious and healing rituals. Spanish missionaries in the 1500s attempted to destroy all records and evidence of the use of these mushrooms. Nevertheless, a 16th century Spanish Franciscan friar and historian mentioned teonanacatl in his extensive writings, intriguing 20th century ethnopharmacologists and leading to a decades-long search for the identity of teonanacatl. Their search ultimately led to a 1957 photo-essay in a popular magazine, describing for the Western world the use of these mushrooms. Specimens were ultimately obtained, and their active principle identified and chemically synthesized. In the past 10–15 years several FDA-approved clinical studies have indicated potential medical value for psilocybin-assisted psychotherapy in treating depression, anxiety, and certain addictions. At present, assuming that the early clinical studies can be validated by larger studies, psilocybin is poised to make a significant impact on treatments available to psychiatric medicine.
