In the contemporary landscape of psychiatric medicine, critical advancements have been noted in the utilization of psychoactive substances such as hallucinogens, 3,4-methylenedioxymethamphetamine (MDMA), and ketamine for the treatment of severe mental health disorders. This review provides a detailed evaluation of these substances, focusing on their mechanis...
A man with AUD achieves sobriety on treatment with an SSRI and naltrexone, but then stops taking the SSRI to participate in a psilocybin “ceremony.” What factors contributed to his subsequent relapse to alcohol use?
Abstract Background Psychedelic use and its impact on well-being is garnering a lot of research attention, however, little has been done to understand the potential associations between multiple characteristics of the psychedelic experience and psychological flexibility (PF), which encompasses a conscious awareness of thoughts and behavior, allowing individu...
This work utilized fMRI to assess the influence of the psychedelics, Psilocybin, a serotonergic agonist, and Salvinorin-A, a kappa-opioid receptor (KOR) agonist, on functional connectivity (FC) in non-human primates. We used a seed-based FC analysis, probing regions of interest associated with psychedelic hallucinogens. Our findings highlight the overlapping...
Depression is a global public health challenge that represents the world's largest cause of disability, especially in the context of traditional treatments. One potential solution being explored is psilocybin assisted psychotherapy (PAP) which shows promise for treating depression. A recent study by Rosenblat et al. explores the use of psilocybin in clinical...
Recent experience with off-label use of ketamine and recent challenges experienced in research with MDMA and psilocybin provide additional perspectives on how best to continue development of experimental psychedelic medications. Andrews et al. [1] provide a valuable perspective by noting the parallels between the ongoing deregulation of cannabis and what is ...
. It remains unclear how human brain network changes relate to subjective and lasting effects of psychedelics. Here we tracked individual-specific brain changes with longitudinal precision functional mapping (roughly 18 magnetic resonance imaging visits per participant). Healthy adults were tracked before, during and for 3 weeks after high-dose psilocybin (2...
Psilocybin has reemerged as a promising treatment for difficult-to-treat depression (DTD). Although there is limited evidence regarding interactions between psilocybin and other psychotropic drugs, clinical trials require that patients discontinue their antidepressants before study entry to isolate the benefits of psilocybin and to minimize the risk of adver...
Psilocybin is a psychedelic compound found in some hallucinogenic "magic mushrooms". Psilocin is the active metabolite of Psilocybin, and it is the subject of several studies for the treatment of psychological disorders, such as anxiety, depression, and post-traumatic stress disorder. As such, the pharmacokinetic properties of psilocin should be evaluated to...
RATIONALE: Our study aimed to unravel the unknown mechanisms behind the exceptional efficacy of Psilocybin (PSI) in treating treatment-resistant depression (TRD). Focusing on Wistar-Kyoto (WKY) rats with a TRD phenotype and Wistar (WIS) rats as a normative comparison, we investigated behavioral and neuroplasticity-related responses to PSI, striving to shed l...
Psychedelics, substances known to alter perception, mood, and consciousness, have been used across various cultures for centuries, often in religious ceremonies to facilitate spiritual experiences. Lysergic acid diethylamide (LSD) was used clinically from the 1950s until its ban in 1967. Recently, there has been a resurgence of interest in psychedelics for t...
The extent of changes in functional connectivity (FC) within functional networks as a common feature across hallucinogenic drug classes is under-explored. This work utilized fMRI to assess the dissociative hallucinogens Psilocybin, a classical serotonergic psychedelic, and Salvinorin-A, a kappa-opioid receptor (KOR) agonist, on resting-state FC in nonhuman p...
Data on medication interactions with psychedelics are limited. Here we present what may be the first published report of a hypertensive emergency following the combination of psilocybin mushrooms with a monoamine oxidase inhibitor (MAOI). A42-year-old man with treatment-resistant major depressive disorder took 1 g of Psilocybe cubensis mushrooms, while presc...
Several fungi belonging to the genus Psilocybe, also called “magic mushrooms”, contain the hallucinogenic drugs psilocybin and psilocin. They are chemically related to serotonin (5-HT). In addition to being abused as drugs, they are now also being discussed or used as a treatment option for depression. Here, we hypothesized that psilocybin and psilocin may a...
Resistance to traditional treatment methods is still a major obstacle in modern psychiatry. As a result, several studies are currently being conducted to find effective alternatives to traditional therapies. One of these alternatives is psilocybin, a psychedelic substance that has been tested in clinical trials as an adjunct to psychotherapy. These studies f...
Introduction: Psilocybin is a naturally occurring tryptamine derivative psychedelic compound potently produced by fungi members of the genus Psilocybe. Previous literature has highlighted psilocybin as a serotonin 2A receptor agonist with striking effects on neural plasticity and cognition. Recent studies explore the usage of psilocybin in addressing addicti...
