Treating posttraumatic stress disorder with MDMA-assisted psychotherapy: A preliminary meta-analysis and comparison to prolonged exposure therapy

April 26, 2016 / Anxiety Disorders / PTSD, MDMA, Papers, Psychology, Publications / By / ,

Abstract

Since the wars in Iraq and Afghanistan, posttraumatic stress disorder (PTSD) has become a major area of research and development. The most widely accepted treatment for PTSD is prolonged exposure (PE) therapy, but for many patients it is intolerable or ineffective. ±3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy (MDMA-AP) has recently re-emerged as a new treatment option, with two clinical trials having been published and both producing promising results. However, these results have yet to be compared to existing treatments. The present paper seeks to bridge this gap in the literature. Often the statistical significance of clinical trials is overemphasized, while the magnitude of the treatment effects is overlooked. The current meta-analysis aims to provide a comparison of the cumulative effect size of the MDMA-AP studies with those of PE. Effect sizes were calculated for primary and secondary outcome measures in the MDMA-AP clinical trials and compared to those of a meta-analysis including several PE clinical trials. It was found that MDMA-AP had larger effect sizes in both clinician-observed outcomes than PE did (Hedges’ g=1.17 vs. g=1.08, respectively) and patient self-report outcomes (Hedges’ g=0.87 vs. g=0.77, respectively). The dropout rates of PE and MDMA-AP were also compared, revealing that MDMA-AP had a considerably lower percentage of patients dropping out than PE did. These results suggest that MDMA-AP offers a promising treatment for PTSD.

Novel psychopharmacological therapies for psychiatric disorders: psilocybin and MDMA

April 5, 2016 / Anxiety Disorders / PTSD, MDMA, Mushrooms / Psilocybin, Papers, Psychology, Publications, Substance Use Disorder / By / , ,

Abstract

4-phosphorloxy-N,N-dimethyltryptamine (psilocybin) and methylenedioxymethamfetamine (MDMA), best known for their illegal use as psychedelic drugs, are showing promise as therapeutics in a resurgence of clinical research during the past 10 years. Psilocybin is being tested for alcoholism, smoking cessation, and in patients with advanced cancer with anxiety. MDMA is showing encouraging results as a treatment for refractory post-traumatic stress disorder, social anxiety in autistic adults, and anxiety associated with a life-threatening illness. Both drugs are studied as adjuncts or catalysts to psychotherapy, rather than as stand-alone drug treatments. This model of drug-assisted psychotherapy is a possible alternative to existing pharmacological and psychological treatments in psychiatry. Further research is needed to fully assess the potential of these compounds in the management of these common disorders that are difficult to treat with existing methods.

Can ecstasy treat the agony of PTSD?

April 1, 2016 / Anxiety Disorders / PTSD, MDMA, Papers, Psychology, Publications / By /

Abstract

Two serotonin reuptake inhibitors (SSRIs) have received FDA indication for treatment of PTSD, however the effectiveness of pharmacotherapy for PTSD is limited. Psychotherapy, including several well established evidence based methods, is the mainstay of PTSD treatment. Despite advances in this area, a significant percentage of PTSD patients are refractory to existing treatments. Recent research has explored the possibility that certain drugs could increase the effectiveness of psychotherapy when administered intermittently in conjunction with psychotherapy sessions. The most robust published. Results to date using this approach have been in early clinical trials of±3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy. These studies primarily involved civilians with treatment-resistant, crime-related PTSD. A more recent phase 2 trial, completed in 2015 yielded equally promising. Results in a cohort of military veterans, police officers and firefighters, mostly veterans from the wars in Iraq and Afghanistan.In these double blind controlled trials subjects with PTSD refractory to prior treatment are randomized to an active dose of MDMA or an active or inactive placebo administered to each individual on only two or three occasions during eight-hour psychotherapy sessions one month apart, in conjunction with preparatory and follow-up psychotherapy sessions. Outcome measures are repeated one or two months after the second MDMA-assisted session before the blind is broken. Subjects who were randomized to full dose MDMA are then eligible for one additional, open label, MDMA-assisted session. Those randomized to placebo or a lower dose of MDMA are eligible for three open-label full dose sessions. Outcome measures are repeated two months following the third MDMA-assisted session. The primary outcome measure is the Clinician Administered PTSD Scale (CAPS). Additional measures include the Beck Depression Inventory-II (BDI-II), Global Assessment of Functioning (GAF), Pittsburgh Sleep Quality Index (PSQI) and Posttraumatic Growth Inventory (PTGI).In the original study comparing MDMA with inactive placebo along with the same psychotherapy PTSD was resolved in 83% of the MDMA group vs. 25% of the placebo group receiving the same therapy. Improvement was maintained for at least 74% of subjects at long-term follow-up a mean of 45 months later. In a more recent, unpublished, study both the high dose and the medium dose of MDMA showed large effect sizes in reducing CAPS scores, and improvements in secondary measures: and BDI-II, PSQI, GAF and PTGI.Evidence in phase II trials suggest that MDMA-assisted psychotherapy is effective in treating PTSD in both civilians and veterans who have not responded to established treatments. Phase III trials are necessary to definitively establish safety and efficacy of MDMA-assisted psychotherapy for PTSD.

Antidepressive and anxiolytic effects of ayahuasca: a systematic literature review of animal and human studies

March 24, 2016 / Anxiety Disorders / PTSD, Ayahuasca, Depressive Disorders, Papers, Psychology, Publications / By / , , ,

Abstract

Objective:

To conduct a systematic literature review of animal and human studies reporting anxiolytic or antidepressive effects of ayahuasca or some of its isolated alkaloids (dimethyltryptamine, harmine, tetrahydroharmine, and harmaline).

Methods:

Papers published until 3 April 2015 were retrieved from the PubMed, LILACS and SciELO databases following a comprehensive search strategy and using a predetermined set of criteria for article selection.

Results:

Five hundred and fourteen studies were identified, of which 21 met the established criteria. Studies in animals have shown anxiolytic and antidepressive effects of ayahuasca, harmine, and harmaline, and experimental studies in humans and mental health assessments of experienced ayahuasca consumers also suggest that ayahuasca is associated with reductions in anxiety and depressive symptoms. A pilot study reported rapid antidepressive effects of a single ayahuasca dose in six patients with recurrent depression.

Conclusion:

Considering the need for new drugs that produce fewer adverse effects and are more effective in reducing anxiety and depression symptomatology, the described effects of ayahuasca and its alkaloids should be further investigated.

Lysergic acid diethylamide: a drug of ‘use’?

March 23, 2016 / Anxiety Disorders / PTSD, LSD, Papers, Psychology, Publications / By / , , , ,

Abstract

Lysergic acid diethylamide (LSD), described as a classical hallucinogen, began its journey from the middle of the last century following an accidental discovery. Since then, it was used as a popular and notorious substance of abuse in various parts of the world. Its beneficial role as an adjunct to psychotherapy was much unknown, until some ‘benevolent’ experiments were carried out over time to explore some of its potential uses. But, many of its effects were unclear and seemed to be a psychedelic enigma. In this review article, we have described the receptor pharmacology, mechanism of action, effects and adverse effects of LSD on the normal body system. We have also highlighted its addictive potentials and the chances of developing tolerance. We have assimilated some of the interesting therapeutic uses of this drug, such as an antianxiety agent, a creativity enhancer, a suggestibility enhancer, and a performance enhancer. We have also described LSD to be successfully used in drug and alcohol dependence, and as a part of psychedelic peak therapy in terminally ill patients. The relevant chronological history and literature in the light of present knowledge and scenarios have been discussed. Based on available evidence, LSD could be tried therapeutically in certain specific conditions under controlled settings. But as we mention, due to all the safety concerns, the use of this nonaddictive ‘entheogen’ in actual practice warrants a lot of expertise, caution, cooperation and ethical considerations.

Antidepressive, anxiolytic, and antiaddictive effects of ayahuasca, psilocybin and lysergic acid diethylamide (LSD): a systematic review of clinical trials published in the last 25 years

Abstract

To date, pharmacological treatments for mood and anxiety disorders and for drug dependence show limited efficacy, leaving a large number of patients suffering severe and persistent symptoms. Preliminary studies in animals and humans suggest that ayahuasca, psilocybin and lysergic acid diethylamide (LSD) may have antidepressive, anxiolytic, and antiaddictive properties. Thus, we conducted a systematic review of clinical trials published from 1990 until 2015, assessing these therapeutic properties. Electronic searches were performed using the PubMed, LILACS, and SciELO databases. Only clinical trials published in peer-reviewed journals were included. Of these, 151 studies were identified, of which six met the established criteria. Reviewed studies suggest beneficial effects for treatment-resistant depression, anxiety and depression associated with life-threatening diseases, and tobacco and alcohol dependence. All drugs were well tolerated. In conclusion, ayahuasca, psilocybin and LSD may be useful pharmacological tools for the treatment of drug dependence, and anxiety and mood disorders, especially in treatment-resistant patients. These drugs may also be useful pharmacological tools to understand psychiatric disorders and to develop new therapeutic agents. However, all studies reviewed had small sample sizes, and half of them were open-label, proof-of-concept studies. Randomized, double-blind, placebo-controlled studies with more patients are needed to replicate these preliminary findings.

Effects of 3,4-Methylenedioxymethamphetamine on Patient Utterances in a Psychotherapeutic Setting

March 17, 2016 / Anxiety Disorders / PTSD, MDMA, Papers, Psychology, Publications / By / , ,

Abstract

3,4-Methylenedioxymethamphetamine (MDMA) administered as an adjunct to talk therapy influences patient speech content and increases improvement in treatment-resistant posttraumatic stress disorder (PTSD). Data came from the recordings of Mithoefer et al. (2011). In the third therapeutic session studied, patients were assigned, double blind, to an MDMA or a placebo group. Condition-blind scorers listened to therapy recordings and scored utterances where patients initiated topics that were empathic (regarding others’ emotions), entactic (requesting or appreciating physical touch), or ensuic (describing a change in their sense of themselves). Patients who received MDMA produced high levels of ensuic, empathic, and entactic utterances compared with those who received the placebo. Interrater discourse scoring was reliable. The relationship between the number of scored utterances and the Clinician Administered PTSD Scale scores measuring PTSD severity after the treatment was significant, and reanalysis grouped bimodally into “many” or “few” such utterances remained significant. MDMA assisted these patients in having meaningful and disorder-resolving thoughts and discourse in talk therapy.

Ayahuasca: pharmacology, neuroscience and therapeutic potential

March 11, 2016 / Anxiety Disorders / PTSD, Ayahuasca, Depressive Disorders, Neuroscience, Papers, Psychology, Publications / By / , , , , , ,

Abstract

Ayahuasca is the Quechua name for a tea obtained from the vine Banisteriopsis caapi, and used for ritual purposes by the indigenous populations of the Amazon. The use of a variation of the tea that combines B. caapi with the leaves of the shrub Psychotria viridis has experienced unprecedented expansion worldwide for its psychotropic properties. This preparation contains the psychedelic 5-HT2A receptor agonist N,N-dimethyltryptamine (DMT) from P. viridis, plus β-carboline alkaloids with monoamine-oxidase-inhibiting properties from B. caapi. Acute administration induces a transient modified state of consciousness characterized by introspection, visions, enhanced emotions and recollection of personal memories. A growing body of evidence suggests that ayahuasca may be useful to treat substance use disorders, anxiety and depression. Here we review the pharmacology and neuroscience of ayahuasca, and the potential psychological mechanisms underlying its therapeutic potential. We discuss recent findings indicating that ayahuasca intake increases certain mindfulness facets related to acceptance and to the ability to take a detached view of one’s own thoughts and emotions. Based on the available evidence, we conclude that ayahuasca shows promise as a therapeutic tool by enhancing self-acceptance and allowing safe exposure to emotional events. We postulate that ayahuasca could be of use in the treatment of impulse-related, personality and substance use disorders and also in the handling of trauma. More research is needed to assess the full potential of ayahuasca in the treatment of these disorders.
