ABSTRACT Background: Psychedelic substances are increasingly recognized for their therapeutic potential to ease psychological suffering linked to end-of-life issues. However, amid renewed scientific and public interest, policy remains restrictive. Existing reviews have made progress in synthesizing the results of studies of psychedelic interventions, especia...
Introduction: The classic psychedelic psilocybin has attracted special interest across clinical and non-clinical settings as a potential tool for mental health. However, despite increasing attention to challenging psychedelic experiences, few studies have explored the relevance of emotionally painful, shame-related processes with psychedelic use. Methods: Th...
Executive function deficits, common in psychiatric disorders, hinder daily activities and may be linked to diminished neural plasticity, affecting treatment and training responsiveness. In this pioneering study, we evaluated the feasibility and preliminary efficacy of psilocybin-assisted frontal-midline theta neurofeedback (NF), a neuromodulation technique l...
This retrospective case report explores the impact of psilocybin mushroom intake on the emergence of mental imagery in an autistic woman with aphantasia. Aphantasia refers to the inability to generate visual mental images, which can significantly affect individuals' experiences and cognitive processes. The case study focuses on a 34-year-old autistic woman w...
Background: Psychedelic-assisted therapy has gained significant attention in recent years. However, there is a lack of empirical clarity on the role of psychosocial interventions (PI) in clinical trials of psychedelic treatment due in part to deficiencies in reporting practices found in the existing literature. These PI include non-drug support or interventi...
This work is a literature review on the use of psilocybin in psychotherapeutic treatment of mental illnesses. The review answers the question of what opportunities and risks are associated with the use of the psychoactive substance psilocybin. Peer-reviewed studies between 2017 and 2022 were included. Nine studies were found regarding the following indicatio...
Flotation-Reduced Environmental Stimulation Therapy (REST) and mindfulness meditation (MM) are known to induce altered states of consciousness (ASC) and self-consciousness. In this study, we use a phenomenological and predictive processing (PP) framework to compare the interventions alongside the psychedelic experience. Ego-dissolution scores were greater th...
This retrospective study presents the case of a young woman in her mid-twenties who suffered from insecurity and abandonment-related anxiety, which intensified after a breakup of her relationship. Her parents' alcoholism and schizophrenia, as well as emotional and physical violence, had been a part of her childhood, but they had appeared 'normal' to her. Her...
Recent studies suggest psychedelic use may be associated with changes in a variety of beliefs or belief-like states, including increased 1) mind perception, 2) non-naturalistic beliefs, and 3) Atheist-Believer status (e.g., believer, agnostic, or non-believer). We conducted a prospective longitudinal study among participants (N = 657) who planned to have a p...
This article presents the case of a young woman in her mid-twenties with a history of depression since childhood. She lived with a mother who failed to take care of her. The patient cared for the emotional needs of the mother instead of the mother caring for the daughter's needs. Her father was mostly absent. Already around the age of thirteen, the patient w...
The Altered Xperience Project (AXP) is an ongoing research project that takes the form of an open citizen science initiative. Its main goal is to systematically collect and consolidate data on the subjective experiences induced by various consciousness-manipulating techniques (CMTs). These include both psychoactive substances as well as non-pharmacological m...
Some recent research and commentary have suggested that most or all the effects reported by people who microdose psychedelics may be explained by expectations or placebo effects. Here we step through all the available evidence from dose-controlled studies that have investigated the effects of low doses of LSD and psilocybin. We suggest eight reasons why curr...
Preparing participants for psychedelic experiences is crucial for ensuring these experiences are safe, and potentially, beneficial. However, there is currently no validated measure to assess the extent to which participants are well-prepared for such experiences. Our study aimed to address this gap by developing, validating, and testing the Psychedelic Prepa...
The Yale Program for Psychedelic Science (YPPS) supports a multi-disciplinary research community dedicated to investigating the effects of psychedelic substances on brain function, cognition, and behavior, including their therapeutic potential in treating neuropsychiatric conditions. In support of this mission, YPPS is testing the safety and efficacy of psil...
In this pilot study 12 adult outpatients with body dysmorphic disorder that has not responded to at least one adequate trial of a serotonin reuptake inhibitor will be treated openly with a single oral dose of psilocybin. Followup visits to monitor safety and clinical outcome will be conducted over a 3 month period. In this pilot study, up to 12 adult outpati...
In recent psychedelic therapy research, the concept of 'mystical experience' has been highlighted, as in several studies it has been identified as a significant predictor of improved outcome. Many studies mentioning the concept, for example, reports of randomized clinical trials, typically do not provide detailed examples of such experiences, however. In ord...
In medicine, psychedelics were initially considered as a tool for clinicians to understand psychotic states. Based on the presented case data, a reversal of that concept is proposed: psychedelics could be conceptualized as a tool for people chronically anxious and depressed since early childhood to understand ordinary states of mind (e.g. calmness, hopefulne...
While a relatively large body of research exists on many aspects of psychedelic therapy, articles describing a complete, successful treatment process are rarely found. This article therefore presents a case of a woman in her early forties with early complex trauma due to domestic violence, sexual abuse and poverty in her childhood, resulting in approximately...
Self or ego dissolution (SED) is a recurring, yet vaguely defined phenomenon often associated with positive therapeutic outcomes within clinical research on classic psychedelic substances. The aim of this thesis is to achieve a deeper understanding and improve terminological clarity of SED in a psychedelic context, here defined as research settings in which ...
This is the French translation of the Yale Manual for Psilocybin-Assisted Therapy of Depression. Le Manuel de Yale pour le traitement thérapeutique de la dépression assisté par la psilocybine fournit aux chercheurs et aux thérapeutes des méthodes, une structure et des domaines à prendre en compte concernant l'utilisation de la thérapie assistée par les psych...
