There remain significant gaps in knowledge about best practices for facilitated psychedelic care and psychedelic-assisted therapy. To inform the development of service models that support safe and beneficial experiences, this qualitative study explored expert perspectives on current and ideal standards of care, including key practices (e.g., screening, adapt...
BACKGROUND: Psychedelics such as 3,4-methylenedioxymethamphetamine (MDMA) and psilocybin are showing promising results in clinical trials for the treatment of mental health disorders, including post-traumatic stress disorder, addiction, and treatment-resistant depression. US Food and Drug Administration approval may be on the horizon. Yet, little is known ab...
Classical psychedelics, like lysergic acid diethylamide (LSD), N,N-dimethyltryptamine (DMT), and psilocybin, can alter perception, emotion, and cognition, and have shown promise as 're-purposed' treatments for some psychiatric disorders. Recent trials have, e.g., demonstrated rapid and sustained symptom relief in treatment-resistant depression. While promisi...
BACKGROUND: Obsessive-compulsive disorder (OCD) is a debilitating mental disorder commonly treated with selective serotonin reuptake inhibitors, atypical antipsychotic augmentation and cognitive-behavioural therapy. However, up to 60% of people with OCD do not respond to these treatments. Therefore, a novel intervention, psilocybin-assisted psychotherapy (PA...
Metastability of BOLD fMRI signals is a commonly used proxy of brain dynamics in behavioral and clinical studies. To date, little has been done to assess the confidence with which we can use estimates of metastability as reliable biomarkers of individual brain state. We analyze whole-brain and network-specific metastability for a highly sampled individual br...
Microdosing - the practice of consuming extremely low doses of classical psychedelic substances that do not elicit overt psychedelic effects - has gained significant attention as a potential method for enhancing cognitive performance. However, findings from controlled studies remain mixed and inconclusive. This preregistered meta-analysis examined the cognit...
The meta-analysis of the 11-dimensional Altered States of Consciousness (11D-ASC) included three studies that contained duplicated data from other papers: Duerler et al. (2021), Lewis et al. (2017), and Preller et al. (2017). When these studies are removed from the analysis, the results are generally similar to the previously reported findings. Out of 33 com...
OBJECTIVE: Despite growing research on the potential mental health benefits of psychedelics, there has been limited study of these drugs in populations with obsessive-compulsive disorder (OCD) and with Hispanic and Latin American (H/L) ancestry. METHODS: Demographic and clinical assessments were conducted as part of the Latin American Trans-ancestry Initiati...
The Hamas-led attack in southern Israel on October 7, 2023 was one of the deadliest terror attacks in history, resulting in 1,182 fatalities, over 4,000 wounded, and 251 taken hostage1. The Nova festival, an 18-hour rave held in the Gaza Envelope region, suffered the highest casualties in the attack, with over 370 killed. For the Nova attendees, the highligh...
High Resolution Image Download MS PowerPoint Slide Mental disorders of the global population have been evaluated statistically by decades. Psilocybin has medicinal properties with potential pharmaceutical applications for treatment of psychological disorders. This component is present naturally in mushrooms of the Psilocybe genus and is primarily responsible...
In the 1950s-60s, serotonergic psychedelic drugs were studied as potential adjuvants to psychotherapy to treat addiction and alcoholism. However, starting in the 70s, preclinical and clinical studies on psychedelics stopped for decades because legislation controlled its recreational use, citing their hallucinogenic and psychotomimetic effects, as well as the...
The Psilocybe genus is known for producing tryptamine alkaloids, specifically the compounds psilocybin and psilocin, which have shown antidepressant and anxiolytic potential. The presence of these alkaloids makes Psilocybe mushrooms promising sources of molecules with potential applications in the treatment of mental disorders. To explore this, a bibliograph...
Opioid-related overdose deaths have reached record high levels, and novel treatments for opioid use disorder (OUD) are needed. The three United States Food and Drug Administration (FDA)-approved medications for OUD function primarily at the mu-opioid receptor. While these remain the gold-standard treatment for OUD, they have shortcomings and treatment option...
Psilocybin is a psychedelic serotonergic compound that is renowned for its potent psychoactive effects. Over the past 15 years, an increasing number of controlled clinical trials showed that it has a fast-acting and sustainable efficacy in treating various psychiatric disorders. Neuroimaging studies have been conducted with the objective of elucidating the n...
This thesis explores the psychosocial mechanisms underlying therapeutic responses to psychedelic interventions, advancing an enactive biopsychosocial perspective that foregrounds dynamic and reciprocal causal relationships between biological, psychological, and social processes. While clinical studies increasingly demonstrate the efficacy of serotonergic psy...
Depression affects over 185 million people worldwide, with approximately one-third classified as treatment-resistant depression (TRD). Current treatments, such as oral antidepressants, often take around 3 weeks to become effective, with no immediate anti-suicidal benefits. The field urgently needs innovative therapies that provide rapid relief. Psychedelics ...
