ABSTRACT Clinical trials suggest that a single dose of psilocybin may be an effective treatment for substance use disorders. Choice impulsivity is a value-based decision-making bias that predicts drug-intake escalation and is commonly associated with substance use disorders. The dorsomedial prefrontal cortex regulates choice impulsivity and is enriched with ...
Mescaline, a 5-HT2A agonist psychedelic used ceremonially for millennia, lacks neuroimaging characterization due to its Schedule 1 status. Using pharmacological and resting-state fMRI in awake rats, we report mescaline's first comprehensive neurobiological profile. Acutely, mescaline produced cerebellar-selective BOLD suppression, suggesting functional disco...
PURPOSE: The purpose of this review is to evaluate which psychedelics have the most efficacy data to support their use in the treatment of posttraumatic stress disorder (PTSD). This review also aims to assess safety data and concerns related to psychedelic therapies and identify demographic characteristics that may influence clinical outcomes. SUMMARY: A sys...
As psychedelic-assisted psychotherapy gains momentum, clinical investigation of next-generation psychedelics may lead to novel compounds tailored for specific populations. 2,5-dimethoxy-4-bromophenethylamine (2C-B) is a psychedelic phenethylamine reported to produce less dysphoria and subjective impairment than the psychedelic tryptamine psilocybin. Despite ...
INTRODUCTION: Sertonergic psychedelics LSD, psilocin and DMT, have been shown to hold a great potential for treatment of various neuropsychiatric conditions, such as major depressive disorder, addiction, and end-of-life anxiety. Effects of these substances on neuronal activity and plasticity have been demonstrated, however, better understanding of their mech...
This study aims to explore the safety and tolerability of a single dose of psilocybin (25mg) administered under supportive conditions to adult participants with TRD and chronic suicidal ideation
Psilocybin, a compound found in Psilocybe mushrooms, is emerging as a promising treatment for neurodegenerative and psychiatric disorders, including major depressive disorder. Its potential therapeutic effects stem from promoting neuroprotection, neurogenesis, and neuroplasticity, key factors in brain health. Psilocybin could help combat mild neurodegenerati...
"Iracema comes with the pot full of the green liquor. The shaman decrees the dreams to each warrior and distributes the wine of jurema, which carries the brave Tabajara to heaven." José de Alencar, in his poetic novel “Iracema” (1865)1. IntroductionThe "wine of jurema", used in ancient Brazilian shamanic rituals, is rich in N,N-dimethyltryptamine (DMT), a na...
The primary objective of this study is to evaluate the efficacy of psilocybin (25 mg) administered under supportive conditions to adult participants with severe TRD, in improving depressive symptoms.
The primary objective of this study is to evaluate the efficacy of 25 mg of psilocybin under supportive conditions to adult participants with BP-II, current episode depressed, in improving depressive symptoms.
Psychiatric illnesses - such as major depressive disorder, anxiety disorder, substance use disorder, and posttraumatic stress disorder (PTSD) - are widely prevalent and represent a substantial health burden worldwide. Yet, conventional medications for mental illnesses often fail to provide relief to patients' disruptive and disabling symptoms. Existing and e...
Sexual trauma is a life-altering violation with persistent, long term implications for survivors. Trauma can produce distinctive impacts on individuals, and therapeutic approaches that offer healing to some, may not be effective for others, particularly when the memories of trauma are implicit and are not easily treated through evidence-based therapeutic met...
Objective: The objective of this selective EBM review is to determine whether or not psilocybin is an effective treatment to reduce depression and anxiety in cancer patients with a diagnosis of an anxiety disorder, mood disorder, and/or stress disorder. Study design: Systematic review of three cross-over randomized placebo-controlled trials published in peer...
OBJECTIVE: The objective of this selective Evidence Based Medicine (EBM) review is to determine whether or not “Are psychedelics effective in treating anxiety associated with a lifethreatening disease?” STUDY DESIGN: Review of two double-blind, randomized, placebo-controlled pilot studies and one randomized controlled trial (RCT). DATA SOURCES: All studies w...
The development of pharmacological magnetic resonance imaging (phMRI) has presented the opportunity for investigation of the neurophysiological effects of drugs in vivo. Psilocin, a hallucinogen metabolised from psilocybin, was recently reported to evoke brain region-specific, phMRI signal changes in humans. The present study investigated the effects of psil...
