Although research on psychedelics (hallucinogenic serotonin 2 A or 5-HT2A agonists) has shown initial promise in ameliorating a range of psychiatric conditions, the mechanisms by which psychedelics promote therapeutic benefits have yet to be elucidated. Researchers have posited enhancements in cognitive flexibility as a transdiagnostic mechanism through which psychedelics could disrupt...

Classical psychedelics-a broad class of compounds that include psilocybin, lysergic acid diethylamide, dimethyltryptamine, and mescaline-have shown significant promise for the treatment of mental health conditions in recent clinical trials. Organizations such as the National Network of Depression Centers (NNDCs) can play a pivotal role in uniting researchers and clinicians working in this field...

Ketamine is known to be a rapid-acting antidepressant, but there is limited evidence regarding which types of patients are best-suited to this treatment and whether adjunctive psychotherapy improves outcomes. In a sample of 224 patients who received five ketamine infusions at a private clinic, this study uses Bayesian mixed modeling to examine the effects of early life stress (measured with the...

The potential for psilocybin, and other psychedelic drugs, to fulfil a much needed and potentially transformative class of psychiatric treatments has garnered significant attention. Consequently, there has been a great deal of interest and investment in accelerating its development and potential implementation in routine clinical practice. However, the expanding scope of scientific discovery,...

3,4-methelenedioxymethamphetamine (MDMA) can be effective in treating posttraumatic stress disorder (PTSD) in controlled trials, potentially secondary to MDMA’s effects on neural circuits implicated in fear and reward. Although anxiety, stress, and fear-based disorders involve maladaptation of the neural circuits processing fear, threat, and reward, no studies have tested MDMA’s therapeutic...

MDMA (i.e., 3,4-methylenedixoymethamphetamine), commonly known as "Ecstasy" or "Molly," has been used since the 1970s both in recreational and therapeutic settings. The Food and Drug Administration (FDA) designated MDMA-Assisted Therapy (MDMA-AT) as a Breakthrough Therapy for posttraumatic stress disorder (PTSD) in 2017, and the FDA is requiring an additional phase 3 trial after rejecting the...

The evidence is currently insufficient to recommend psilocybin with PST as a psychiatric treatment. Additional rigorously designed clinical trials are needed to definitively establish efficacy in larger and more diverse samples, address dosing considerations, improve blinding, and provide information on mechanisms of action and moderators of clinical response. Head-to-head comparisons with...

Posttraumatic stress disorder (PTSD) is a psychiatric disorder with defining abnormalities in memory, and psychedelics may be promising candidates for the treatment of PTSD given their effects on multiple memory systems. Most PTSD and psychedelic research has investigated memory with fear conditioning and extinction. While fruitful, conditioning and extinction provide a limited model of the...

Administration of psychedelics for mental health treatment, typically referred to as "psychedelic-assisted therapy," is a broad term with a very heterogeneous implementation. Despite increasing interest in the clinical application of psychedelic compounds for psychiatric disorders, there is no consensus on how to best integrate the psychedelic experience with evidence-based psychotherapeutic...

Psychedelics (hallucinogenic 5-HT2A agonists such as psilocybin) are gaining recognition for their potential to treat a range of conditions, including anxiety-related psychopathology. Despite early promising results, the mechanisms by which psychedelic therapy alleviates anxiety are not well understood. Here, we review neural and cognitive mechanisms underlying anxiety-related psychopathology...

In recent years, psychedelics have generated considerable excitement and interest as potential novel therapeutics for an array of conditions, with the most advanced evidence base in the treatment of certain severe and/or treatment-resistant psychiatric disorders. An array of clinical and pre-clinical evidence has informed our current understanding of how psychedelics produce profound...
