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...
This study is assessing the efficacy and safety of NPX-5 in psilocybin-assisted psychotherapy for the treatment of adjustment disorder due to cancer diagnosis. Who is it for? This study is for people who are aged between 18 and 80 years old and suffer from anxiety after adjusting to an acutely stressful event of their cancer diagnosis. This is called adjustm...
Selective serotonin reuptake inhibitors (SSRIs) are widely prescribed for mood and anxiety disorders, the same conditions under which psychedelic-assisted therapies are gaining renewed interest. However, it remains unclear how SSRI treatment may influence sensitivity to psychedelics, particularly through the shared engagement of serotonergic pathways. Here, ...
This research study will use computerized tasks, electroencephalography (EEG), and magnetic resonance imaging (MRI) to look at how the drug psilocybin, a naturally occurring compound contained in hundreds of species of psychoactive mushrooms, changes thoughts and brain activity. In this double-blind, placebo-controlled, within-subject, full cross-over study ...
Rationale: Ego-dissolution represents a key therapeutic mechanism in psychedelic-assisted therapy, yet current measurement approaches may inadequately capture its multidimensional nature. Objective: To develop and validate the Multidimensional Ego-Dissolution Assessment (MEDA) and examine substance-specific patterns across classical psychedelics. Methods: It...
Background: Psychedelic therapies are gaining attention as tools to alleviate anxiety and depression across various clinical populations. However, the mechanisms behind psychedelics' therapeutic efficacy and the potential differences in how patients with certain diagnoses experience their subjective effects remain unknown. One commonly suggested mediator of ...
This paper follows 8 scientists who ventured into the world of psychedelics on a quest to find transformational pathways forward. Each have worked on aspects of global environmental change for decades, and observing environmental crises converging into a global polycrisis/metacrisis with genuine potential for collapse, we have all carried psychological burde...
Meaning is a primary existential concern in those with advanced illnesses and functions as an important coping mechanism. Loss of meaning contributes to existential distress, and, in particular, may manifest as demoralization, a syndrome of poor coping that is associated with negative outcomes. Psychedelics are unique psychoactive compounds that, among other...
This article corrects an idea in psychedelic science and culture that the ancient Eleusynian Mysteries used psychedelics, as claimed by Carl Ruck and co-authors in (1978), revitalized by Brian Muraresku's (2020), and popularized by social media heavyweights such as Joe Rogan. It begins by exposing critical methodological flaws in the arguments, namely, a pat...
INTRODUCTION: Psychedelic-assisted therapy shows promise for treating various mental health conditions; however, its reliance on intensive psychological preparation limits its broader application. Digital health interventions have the potential to address this limitation by providing structured, accessible and scalable preparation solutions. This randomised ...
Psychedelic and psychedelic-adjacent substances, including 3,4-methylenedioxymethamphetamine (MDMA) and classic serotonergic hallucinogens, are undergoing renewed therapeutic investigation and remain in non-medical use. Inadvertent exposure during early, unrecognized pregnancy is clinically plausible, yet pregnancy-specific safety evidence is limited. To map...
Classic psychedelics, such as psilocybin, lysergic acid diethylamide (LSD), and N,N-dimethyltryptamine (DMT), have emerged as potent modulators of neuroplasticity and metaplasticity in the adult brain, offering novel therapeutic strategies for neuropsychiatric disorders. Recent findings reveal that beyond their transient psychotropic effects, these compounds...
Background: Major depressive disorder (MDD) is a highly prevalent and disabling psychiatric condition associated with substantial clinical, social, and economic burden [1,2]. Despite the availability of conventional antidepressants, their limited effectiveness, delayed onset of action, and high relapse rates have renewed interest in innovative therapeutic ap...
IMPORTANCE: As psychedelic-assisted therapies gain clinical legitimacy, their cultural portability remains underexamined. While promising results have emerged from trials on existential distress in life-limiting illness, most protocols reflect Euro-American values. The expansion of these therapies calls for a pivot toward cultural humility and renewed attent...
Neuroplasticity refers to the ability of the brain to modify synaptic connections and reorganize neural circuits, underpinning cognitive function, emotional regulation, and recovery from injury. Recent advances have redefined adult neuroplasticity as more dynamic and therapeutically accessible than previously thought, spurring investigation into pharmacologi...
Psilocybin, a classic psychedelic compound, has garnered renewed interest as a potential treatment for various psychiatric disorders. This review provides a comprehensive overview of psilocybin's history, recent clinical evidence, ongoing clinical trials, neuroimaging findings, and regulations. Historically used in spiritual and healing rituals, psilocybin w...
Abstract Lyme disease, caused by the bacterium Borrelia burgdorferi, is the most common vector-borne disease in the United States and Europe. Although antibiotics effectively treat most cases, an estimated 10-20% of patients develop post-treatment Lyme disease (PTLD), a chronic syndrome marked by fatigue, pain, cognitive difficulties, mood disturbance, and r...
The goal of this laboratory study is to establish whether and which microdoses of psilocybin are safe to administer at home to healthy participants. Eligible participants will be given ascending doses of psilocybin trihydrate and a single, interspersed, randomized placebo on separate days in double-blind fashion. The participants will be asked to complete qu...
The aim of this double-blind, placebo-controlled, within-subjects study is to determine whether other psychoactive substances can produce experiences akin to those seen with classic psychedelics. Screening involves a medical and psychiatric examination, including blood draw, history and physical, interviews, and questionnaires. Eligible participants will the...
Abstract Repeated mild traumatic brain injury (RmTBI) can produce lasting cognitive, emotional, and social deficits (e.g., persistent post-concussion symptoms; PPCS). Despite the prevalence of RmTBI in sports, military, and domestic violence settings, effective treatments to alleviate the neurological consequences of RmTBI remain limited. Psilocybin, a serot...
