There is currently renewed interest in the use of psychedelic therapy in the treatment of psychiatric disorders, including depression. The proposed systematic review will aim to identify, evaluate and summarise the psychological processes of change underlying psychedelic therapy for depression in the current literature and consider the implications these pro...
Psilocybin as a novel treatment for depression is garnering a lot of attention from both the mainstream media and the academic community. Although phase 3 trials are only just beginning, we feel that it is important for clinicians to consider what psilocybin-assisted psychotherapy might look like in the clinical setting. In this narrative review article we h...
Despite an increasing body of research highlighting their efficacy to treat a broad range of medical conditions, psychedelic drugs remain a controversial issue among the public and politicians, tainted by previous stigmatisation and perceptions of risk and danger. This narrative review examines the evidence for potential harms of the classic psychedelics by ...
Psilocybin-containing mushrooms have been consumed by various cultures in many different parts of the world for thousands of years. Psilocybin, a classic psychedelic, contains unique psychoactive properties and has been incorporated into religious ceremonies and investigated for its medicinal value. In the mid-20th century, psilocybin, along with most other ...
Current treatment options for major depressive disorder (MDD) have limited efficacy and are associated with adverse effects. Recent studies investigating the antidepressant effect of serotonergic psychedelics-also known as classic psychedelics-have promising preliminary results with large effect sizes. In this context, we conducted a review of the putative n...
Research on the therapeutic potential of psychedelic substances is rapidly expanding. A major limitation within this field is the unpredictability of individual responses to psychedelic substances. A better understanding of factors that can predict psychedelic experience is essential to both clinical progress and wider harm reduction frameworks. Ketamine, MD...
Psychedelic drugs such as psilocybin are under investigation for the treatment of several psychiatric conditions. They also have the remarkable property of producing persisting positive psychological changes in healthy volunteers for at least several months. In this study, 35 medium-high doses of psilocybin were administered to 28 healthy volunteers (12 fema...
Background: Due to increasing evidence of efficacy in treating mental health disorders, psilocybin may become a legal medicinal drug. This study tested the validity of Carhart-Harris & Nutt (2017) model of extra-pharmacological (EP) factors and examined whether such factors should be taken into account in any psychological suitability test for medicinally pr...
Background and Aims: The benefits of classic serotonergic psychedelics (e.g. psilocybin, LSD, DMT, ayahuasca) are becoming more widely known with the resurgence in research in the past decade. Furthermore, the benefits of mindfulness are well documented. However, no systematic reviews have examined linkage of mindfulness and psychedelics use. The aim of this...
Introduction Major depressive disorder is a highly prevalent clinical condition, affecting more than 300 million individuals worldwide. About 1/3 of patients with MDD fail to achieve remission despite treatment with multiple antidepressants and are considered to have treatment-resistant depression (TRD). Novel antidepressants with rapid and sustained effects...
In this précis I summarise the main ideas of my book Philosophy of Psychedelics. The book discusses philosophical issues arising from the therapeutic use of classic psychedelic drugs such as psilocybin and LSD. The book is organised around what I call the Comforting Delusion Objection to psychedelic therapy: the concern that this novel and promising treatmen...
"The Psilocybin for Depression: The ACE Manual '' describes the structure, procedures, and scripts used in the two Imperial College London studies (Psilodep) researching psilocybin treatment for major depression.
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 necessary to...
Introduction: Microdosing refers to the repetitive administration of tiny doses of psychedelics (LSD, Psilocybin) over an extended period of time. This practice has been linked to alleged cognitive benefits, such as improved mood and creativity, potentiated by targeting serotonergic 5-HT2A receptors and facilitating cognitive flexibility. Nonetheless, in the...
Clinical research into serotonergic psychedelic drugs including psilocybin, LSD and N,N-DMT (e.g., in ‘ayahuasca’) is expanding rapidly and clinical trials across a range of psychiatric conditions have shown promising efficacy, with larger trials ongoing. Resting-state functional magnetic resonance imaging (fMRI) has emerged as a brain imaging strategy commo...
Spontaneous Spiritual Awakenings (SSAs) are subjective experiences characterised by a sud- den sense of direct contact, union or merging with a perceived ultimate reality, the universe, or the divine. These profound transformative experiences have scarcely been researched, de- spite extensive anecdotal evidence suggesting their potential to catalyse drastic,...
Objective: Recent clinical trials have demonstrated that psilocybin may have strong antidepressant effects, and may be effective in the treatment of depressive disorders when embedded in a psychotherapeutic protocol (psilocybin-assisted psychotherapy; PAP). However, despite promising results, the mechanism(s) that may be responsible for the antidepressant ef...
After decades of stagnancy, research on psychedelic substances (such as LSD, psilocybin or DMT) has experienced a renaissance over the last 10 years, with various major research programs being conducted across Europe and the United States. This research primarily investigates the potential of psychedelics in the treatment of mental health disorders, their sh...
Dados da Organização Mundial de Saúde (OMS) informam que a depressão circunda entre as doenças mais incapacitantes do mundo, estimando-se que mais de 300 milhões de pessoas sofram com esta patologia. A psilocibina é um princípio ativo extraído do cogumelo do gênero Psilocybe de natureza química semelhante ao neurotransmissor serotonina (5- hidroxitriptamina)...
