Examining the Therapeutic Effect of Ceremonial Ayahuasca on Narcissistic Personality and Antagonistic Externalizing in Adults

Psychoanalytically informed MDMA-assisted therapy for pathological narcissism: a novel theoretical approach

Pathological narcissism (PN) is a complex, treatment-resistant disorder characterized by unstable self-esteem that fluctuates between grandiosity and vulnerability, complicating the formation of a stable self-image. With few empirically supported therapies, treatment has traditionally relied on long-term psychoanalytic approaches, but these often face high attrition. Recent research suggests a potential therapeutic synergy between psychedelics and psychoanalytic therapy, offering a novel approach to addressing entrenched personality structures. Studies on MDMA (3,4-methylenedioxymethamphetamine), a compound known for enhancing empathy, trust, and social interactions, demonstrate potential to reopen critical periods for social learning in adults, offering the possibility of therapeutic benefits for conditions with core issues in relatedness, such as PN. MDMA promotes psychological flexibility and openness, allowing for deeper self-exploration and strengthening the observing ego, considered in psychoanalytic therapy to be an essential component for recognizing and modifying maladaptive patterns. By reducing fear-based avoidance in the brain, MDMA facilitates access to unconscious emotions, helping individuals process overwhelming feelings linked to early relational trauma commonly seen in PN. Additionally, MDMA's capacity to enhance compassion and empathy can fortify the therapeutic alliance, increasing its potential to facilitate relational change. This paper presents an MDMA-assisted therapy (MDMA-AT) tailored for narcissistic patients which is currently being conducted as an investigator-initiated trial (IIT). It explores the model's theoretical foundations, mechanisms of change, treatment framework, and clinical challenges. Combining MDMA with an evidence-based depth therapy like psychoanalytic psychotherapy may offer an innovative treatment for conditions associated with attachment and developmental trauma, particularly personality disorders. While the role of psychotherapy in psychedelic treatments remains a topic of debate, with some proposing psychedelics be administered without psychotherapy, we assert that individuals with early relational trauma stand the most to gain from an integrated psychedelic-assisted therapy (PAT) model, where MDMA enhances the therapeutic alliance and emotional openness while psychoanalytic interventions provide the structure for lasting change.

On Minimizing Risk and Harm in the Use of Psychedelics

Objective

This article outlines recommendations from 30 psychedelic researchers on how to create a better psychedelic safety net.

Methods

A survey of 30 psychedelic researchers asked them to identify key critical research gaps around psychedelic harm and safety.

Results

The critical research gaps identified by the authors included defining the main types of psychedelic harm, the predictors of those harms, and the most effective way to treat those harms. They also call for better support for those experiencing post-psychedelic difficulties, including better online information, peer support groups, affordable therapy, and psychiatric consultation and medication. Finally, the authors call for better funding to create a psychedelic safety net, and suggest psychedelic philanthropists, investors and companies could commit 1% of their investment in psychedelics into supporting safety measures such as research and support services.

Conclusions

The authors identify several practical steps to create a better psychedelic safety net and call for more funding to psychedelic safety measures such as research and support services.

Relevance to clinical practice

The authors outline important gaps in our knowledge around the safety and risk profile of psychedelic medicines and identify practical steps forward for researchers and clinical practitioners to make this promising field safer.

Who are you after psychedelics? A systematic review and a meta-analysis of the magnitude of long-term effects of serotonergic psychedelics on cognition/creativity, emotional processing and personality

This systematic review and a meta-analysis synthesised the results from contemporary, randomized and non-randomized controlled studies to assess lasting (one week minimum) changes on cognition/creativity, emotional processing and personality from serotonergic psychedelics. PubMed, Embase and PsycInfo were searched in July 2022. Risk of bias was assessed using Rob 2.0 and ROBINS-I. Ten studies met the eligibility criteria which involved 304 participants. No statistically significant effects were found for the majority outcome measures across the three constructs. A meta-analysis of emotional recognition outcomes found an overall significant effect for faster reaction times in the active treatment groups for disgust (SMD=-0.63, 95% CI=[-1.01 to -0.25], I2 = 65%) and sadness (SMD=-0.45, 95% CI=[-0.85 to -0.06], I2 = 60%). Future research should include larger samples, better control conditions, standardized doses and longer follow-up periods to confirm these preliminary findings.

Personality change in a trial of psilocybin therapy v. escitalopram treatment for depression

BACKGROUND

Psilocybin Therapy (PT) is being increasingly studied as a psychiatric intervention. Personality relates to mental health and can be used to probe the nature of PT's therapeutic action.

METHODS

In a phase 2, double-blind, randomized, active comparator controlled trial involving patients with moderate-to-severe major depressive disorder, we compared psilocybin with escitalopram, over a core 6-week trial period. Five-Factor model personality domains, Big Five Aspect Scale Openness aspects, Absorption, and Impulsivity were measured at Baseline, Week 6, and Month 6 follow-up.

RESULTS

PT was associated with decreases in neuroticism (B = -0.63), introversion (B = -0.38), disagreeableness (B = -0.47), impulsivity (B = -0.40), and increases in absorption (B = 0.32), conscientiousness (B = 0.30), and openness (B = 0.23) at week 6, with neuroticism (B = -0.47) and disagreeableness (B = -0.41) remaining decreased at month 6. Escitalopram Treatment (ET) was associated with decreases in neuroticism (B = -0.38), disagreeableness (B = -0.26), impulsivity (B = -0.35), and increases in openness (B = 0.28) at week 6, with neuroticism (B = -0.46) remaining decreased at month 6. No significant between-condition differences were observed.

CONCLUSIONS

Personality changes across both conditions were in a direction consistent with improved mental health. With the possible exception of trait absorption, there were no compelling between-condition differences warranting conclusions regarding a selective action of PT (v. ET) on personality; however, post-ET changes in personality were significantly moderated by pre-trial positive expectancy for escitalopram, whereas expectancy did not moderate response to PT.

Ayahuasca: A review of historical, pharmacological, and therapeutic aspects

Ayahuasca is a psychedelic plant brew originating from the Amazon rainforest. It is formed from two basic components, the Banisteriopsis caapi vine and a plant containing the potent psychedelic dimethyltryptamine (DMT), usually Psychotria viridis. Here we review the history of ayahuasca and describe recent work on its pharmacology, phenomenological responses, and clinical applications. There has been a significant increase in interest in ayahuasca since the turn of the millennium. Anecdotal evidence varies significantly, ranging from evangelical accounts to horror stories involving physical and psychological harm. The effects of the brew on personality and mental health outcomes are discussed in this review. Furthermore, phenomenological analyses of the ayahuasca experience are explored. Ayahuasca is a promising psychedelic agent that warrants greater empirical attention regarding its basic neurochemical mechanisms of action and potential therapeutic application.
