BackgroundCurrent first-line treatment for social anxiety disorder (SAD), one of the most prevalent anxiety disorders, is limited in its efficacy. Hence, novel treatment approaches are urgently needed. The current review suggests a combination of meditation-based interventions and the administration of a psychedelic as a future alternative treatment approach...
Psychotherapy with the use of psychedelic substances, including psilocybin, lysergic acid diethylamide (LSD), ketamine, and 3,4-methylenedioxymethamphetamine (MDMA), has demonstrated promise in treatment of post-traumatic stress disorder (PTSD), anxiety, addiction, and treatment-resistant depression. Psychedelic-assisted psychotherapy (PP) represents a uniqu...
Background: Practitioners in a variety of spiritual/religious traditions have described “mystical experiences”, defined by a common set of qualities. The “Mystical Experience Questionnaire” (MEQ30) provides a validated and quantitative measure of mystical experience, and has been used successfully to demonstrate that the hallucinogenic substance psilocybin t...
Mindfulness-based interventions and psychedelic-assisted therapy have been experimentally utilised in recent years as alternative treatments for various psychopathologies with moderate to great success. Both have also demonstrated significant post-acute and long-term decreases in clinical symptoms and enhancements in well-being in healthy participants. These...
The aim of the study is to identify neural signatures, behavioral and phenomenological expressions of self-related processes including: sense of agency, semantic distinction between self and other, selflessness (altruism), social agency, embodied self (interoception), perceptual functioning of dissolved self including hallucinations and crossmodal processing...
Depression is a major public health problem that affects approximately 4.4% of the global population. Since conventional pharmacotherapies and psychotherapies are only partially effective, as demonstrated by the number of patients failing to achieve remission, alternative treatments are needed. Mindfulness meditation (MM) and psilocybin represent two promisi...
This is a double-blind placebo-controlled study investigating the acute and persisting effects of psilocybin on meditation, spirituality, health, well-being, prosocial attitudes, and brain functioning. This study will use questionnaires and functional magnetic resonance imaging (fMRI) to examine the acute and persisting effects of psilocybin on brain functio...
Meditation and psychedelics have played key roles in humankind's search for self-transcendence and personal change. However, neither their possible synergistic effects, nor related state and trait predictors have been experimentally studied. To elucidate these issues, we administered double-blind the model psychedelic drug psilocybin (315 μg/kg PO) or placeb...
In recent years, the scientific study of meditation and psychedelic drugs has seen remarkable developments. The increased focus on meditation in cognitive neuroscience has led to a cross-cultural classification of standard meditation styles validated by functional and structural neuroanatomical data. Meanwhile, the renaissance of psychedelic research has she...
This chapter begins with a brief review of descriptions and definitions of mystical-type experiences and the historical connection between classic hallucinogens and mystical experiences. The chapter then explores the empirical literature on experiences with classic hallucinogens in which claims about mystical or religious experiences have been made. A psycho...
Psilocybin can occasion mystical-type experiences with participant-attributed increases in well-being. However, little research has examined enduring changes in traits. This study administered psilocybin to participants who undertook a program of meditation/spiritual practices. Healthy participants were randomized to three groups (25 each): (1) very low-dose...
Objective: Schizophrenia patients have a higher prevalence of type 2 diabetes mellitus than the general population, and even first-episode, drug-naive (FEDN) patients with schizophrenia have shown a higher prevalence of impaired glucose tolerance (IGT) than the general population. We aimed to investigate the prevalence of abnormal glucose tolerance after glu...
This study will investigate the effects of psilocybin dose and the frequency and intensity of support activities for spiritual practice (e.g., meditation) on a battery of attitudinal and behavioral outcome measures in 75 healthy volunteers who are interested in pursuing a program of spiritual practices with the intention applying spiritual insights and knowl...
The experiences induced by psychedelics share a wide variety of subjective features, related to the complex changes in perception and cognition induced by this class of drugs. A remarkable increase in introspection is at the core of these altered states of consciousness. Self-oriented mental activity has been consistently linked to the Default Mode Network (...
This is a pilot study to finalize methods for a larger study being planned for the future. This research is being done to characterize performance of tasks, brain functioning, and the effects of psilocybin in individuals with a long-term meditation practice. There are three different parts of the pilot study: 1. Effects of psilocybin on psychological functio...
