Emerging evidence indicates the therapeutic potential of psychedelic compounds for post-traumatic stress, yet the mechanisms mediating their effects remain unclear. Delineating the effect of psychedelics on traumatic memory formation could shed light on target therapeutic mechanisms. Here, we report on 343 adult survivors of a single, large-scale terrorist attack taking place during a festival...
AbstractBackground and aimsPsychedelic and MDMA-assisted psychotherapy are at the forefront of new treatment models for mental illnesses such as PTSD and depression, as well as improving well-being. Mindfulness meditation and loving-kindness meditation have also gained research traction, showing promise for enhancing emotional regulation and psychological well-being. This paper explores the...
This Viewpoint explores potential justifications underlying the US Food and Drug Administration (FDA)’s rejection of methylenedioxymethamphetamine (MDMA) as a treatment for posttraumatic stress disorder, including lack of blinding and issues around the integrity of relevant clinical trials.
Abstract Psychedelic treatments like MDMA can sometimes have side effects which persist despite management with Western medical approaches. In what follows, we present a case study of an individual who suffered from insomnia, anxiety, tinnitus, and more for months following MDMA therapy. Ultimately, her symptoms responded to management within the Traditional Chinese Medicine framework. We...
This scoping review addresses the need to comprehensively explore the potential of psychedelic-assisted psychotherapy (PAP) to facilitate recovery from moral injury. Moral injury (MI), characterized by profound psychological distress arising from morally challenging experiences, has garnered increased attention as a complex mental health concern with significant functional sequelae, especially...
Psychedelic-assisted therapy could transform treating psychiatric illness, but harms from exacerbating substance use disorder (SUD) among adults with psychiatric illness using psychedelics have not been studied. A cross-sectional survey in the US was used to test whether Drug Abuse Screening Test scores (DAST-10, validated instrument predicting SUD) were more severe when psychiatric illnesses...
MDMA can cause serious adverse effects on vital organs such as the heart, brain, and liver. Additionally, MDMA consumption can also potentially cause various endocrine system dysfunctions. The previous study has shown that pre-treatment of zinc can reduce the cytotoxicity of MDMA on the Leydig cell line (TM3). In this study, we investigated the mechanisms involved in the treatment with MDMA on...
The recent rejection of 3,4-methylenedioxymethamphetamine (MDMA)-assisted therapy by the U.S. Food and Drug Administration (FDA) is a dramatic moment in the re-emergence of psychedelic research. In this perspective, I argue that it represents a case study for paradigmatic tensions within psychopharmacology. The regulatory system is still influenced by a paradigm that sees the therapeutic...
Given the widespread interest and ongoing study on MDMA-assisted therapy (MDMA-AT) for PTSD, its implications for unique populations-such as adolescents-require further understanding. Social workers will likely play a crucial role in the potential implementation of this intervention, but their perspectives remain unknown. The study includes 222 social workers randomized to read one of two...
Trauma is prevalent, with lifetime estimates of traumatic exposure ranging from 70% for a single event to 31% for multiple events. While many recover, a subset develop post-traumatic stress disorder (PTSD), a debilitating condition characterized by distressing memories, avoidance behaviors, hyperarousal, and mood disturbances. The National Comorbidity Survey reports a lifetime PTSD prevalence...
To critically evaluate published and unpublished systematic reviews and meta-analyses on the safety and efficacy of methylenedioxymethamphetamine-assisted psychotherapy for post-traumatic stress disorder. Six bibliometric databases and grey literature were searched from inception to 9 May 2024 for systematic reviews on the safety and efficacy of methylenedioxymethamphetamine (MDMA)-assisted...
Mental disorders, including anxiety and depression, impact nearly 1 billion people worldwide. Recent research has highlighted the potential of certain amphetamine compounds in the therapy of psychiatric disorders, with 3,4-methylenedioxymethamphetamine (MDMA) emerging as a promising candidate. This study investigates the effects of MDMA on anxiety and social behaviours using 3-week-old...
Rapidly acting therapeutics like 3,4-methylenedioxymethamphetamine (MDMA) are promising treatments for disorders such as posttraumatic stress disorder (PTSD). However, understanding who benefits most and the underlying neural mechanisms remains a critical gap. Stratifying individuals by neural circuit profiles could help differentiate neural, behavioral, and affective responses to MDMA,...
Oxytocin (OXT) deficiency is a recently identified novel psycho-neuroendocrine entity associated with anxiety and reduced prosocial behavior. However, diagnosis and clinical progress have been hindered by challenges in reliably measuring OXT. Neurophysin I (NP-I), an equimolarly co-released cleavage product of the OXT precursor peptide, offers a promising alternative biomarker due to its...
3,4-Methylenedioxymethamphetamine (MDMA) is a widely recognized entactogen frequently used recreationally. It is known for its interaction with the serotonin and oxytocin systems, which underlie its entactogenic effects in humans. Recently, we demonstrated that the gut-brain axis, mediated by the subdiaphragmatic vagus nerve, contributes to MDMA-induced resilience enhancement in rodents. This...
Not for the first time, experts have expressed concern about whether randomized controlled trials (RCTs) can be conducted with psychedelics. A placebo for a drug with such a powerful effect would be difficult to create. But placebos are needed to prove that a medication works because it works, not because the patient thinks it will (the so‐called “placebo effect”). To avoid the placebo effect...
3,4-Methylenedioxymethamphetamine (MDMA), commonly known as a recreational drug, may also offer therapeutic benefits for mental health. Population-based studies suggest that MDMA users have a lower risk of demyelinating diseases, such as depression. Given the role of the gut microbiota in mediating MDMA's effects, we hypothesized that MDMA might confer mental health benefits via the gut-brain...
Psilocybin, MDMA, and LSD have recently emerged as popular psychedelic substances for use in psychopharmacology in managing various disorders including treatment-resistant depression, PTSD, and anxiety. These substances mainly affect the serotonergic receptors that involve the regulation of consciousness, perceptions, and cognition. These unique alterations in brain connectome show the...
Little is known about ecstasy/MDMA use among Asian American and Pacific Islander populations. Research is important because AAPIs face unique cultural factors that may influence use. We estimated the prevalence and correlates of lifetime ecstasy/MDMA use based on a representative sample of US AAPI adults aged ≥18 from the 2015-2020 National Survey on Drug Use and Health. An estimated 5.1% of...
3,4-methylenedioxymethamphetamine (MDMA), a commonly abused recreational drug, induces prosocial effects such as increased sociability and empathy. The nucleus accumbens (NAc) has been suggested to play a crucial role in these MDMA-mediated prosocial effects. However, the relationship between social behavior and NAc neural activity, and the effects of MDMA on this relationship, remain unknown....
