IntroductionAlcohol use disorder is a difficult-to-treat psychiatric disorder and a major burden on public health. Existing treatment efficacy is moderate, and relapse rates are high. Preliminary findings suggest that psilocybin, a psychedelic compound, can safely and reliably occasion highly meaningful experiences that may spur a positive change in drinking...
BackgroundPsychedelic therapy shows promise for Major Depressive Disorder, especially when treatment-resistant, as well as life-threatening illness distress. The objective of this systematic review, inclusive of meta-analysis, is to examine recent clinical research on the therapeutic effects of classic psychedelics on depressive symptoms.MethodsFourteen psyc...

The psychedelic 5-HT2A receptor (5HT2AR) agonist psilocybin (or the active metabolite psilocin) has emerged as potential useful drug for various neuropsychiatric diseases, with a rapid onset of therapeutic activity. However, the mechanisms responsible for such effects remain incompletely characterized. We aimed to study in vitro pharmacological profile and i...
Abstract Objective: Psychedelic-assisted therapies are emerging as safe and effective treatments for some psychological conditions including depression, anxiety, posttraumatic stress disorder, and substance use disorders. As ketamine therapy is already available in general medicine and 3,4 Methylenedioxymethamphetamine (MDMA) and psilocybin are in late-stage...

Improvements to a sense of connectedness to self, others and the wider world have been reported by participants in clinical trials of psychedelic therapy. Such accounts have led us to a definition of the psychological construct of 'connectedness' as 'a state ...
The mystical experience is a potential psychological mechanism to influence outcome in psychedelic therapy. It includes features such as oceanic boundlessness, ego dissolution, and universal interconnectedness, which have been closely linked to both symptom reduction and improved quality of life.

Background: The Relaxed Beliefs Under pSychedelics (REBUS) model proposes that serotonergic psychedelics decrease the precision weighting of neurobiologically-encoded beliefs, and offers a unified account of the acute and therapeutic action of psychedelics. Although REBUS has received some neuroscientific support, little research has examined its psychologic...

BackgroundPatients diagnosed with major depressive disorder (MDD) who fail to respond to two or more antidepressants are often considered to have treatment-resistant depression (TRD). Many of the current options for TRD have significant side effect profiles, are expensive, and are difficult to access. There has been a revival of psychedelic research in recen...

Abstract Psychedelic substances such as psilocybin and ketamine may represent the future of antidepressant treatment, due to their rapid and prolonged effects on mood and cognition. The current body of psychedelic research has focused on administration and treatment within a psychiatric context. Here, instead, we put to the test the contention that it is nec...
12097 Background: More than 17 million people in the U.S. live with cancer and up to 25% of them have major depression. Depression leads to lower treatment adherence, reduced quality of life, and higher rates of mortality in cancer. Yet, interventions used to treat depression in patients with cancer have limited success. Prior trials using psilocybin to trea...
There is currently renewed interest in the use of psychedelic therapy in the treatment of psychiatric disorders, including depression.
