Psychedelic-assisted therapy is gaining recognition for its potential to enhance human functioning. While most research has focused on psychedelic' therapeutic use for mental illness, this review applies the PERMA Theory of Well-Being to systematically examine their role in enhancing well-being in healthy individuals. The final search of five academic databa...
Background and Hypothesis Visual hallucinations (VH) are a core symptom of both Lewy body diseases (LBDs; e.g., Parkinson’s disease and dementia with Lewy bodies) and serotonergic psychedelics (SPs; e.g., psilocybin and mescaline). While these classes of VH differ in etiology, shared pathways are suggested by overlapping phenomenology and neural mechanisms. ...
ObjectivesMood disorders and existential distress impact those with cancer or a serious illness at higher rates than the general population. There have been limited pharmacological advances in recent years, and available psychological interventions vary in degree of impact and durability as a treatment modality in this population. A recent renaissance in psy...
4-bromo-2,5-dimethoxyphenethylamine (2C-B) is a psychoactive substance with reportedly similar acute effects to both the prototypical empathogen 3,4-methylenedioxymethamphetamine (MDMA, Ecstasy) and the classic psychedelic substance psilocybin (contained in "magic, hallucinogenic mushrooms"). Pharmacologically, MDMA mainly releases serotonin (5-HT) via the s...
There is a growing body of clinical research on the therapeutic potential of psychedelics for the treatment of mental health disorders, notably depression. Accordingly, the new revision of the European Medicines Agency guideline on the clinical investigation of products for depression will incorporate a section covering specific regulatory recommendations fo...
Background: Preliminary evidence suggests psilocybin may have therapeutic value for various mental health conditions; despite this, it is currently illegal in the UK. Less is known about how people form their attitudes towards psilocybin policies. Objectives: To explore whether beliefs about the benefits and safety of psilocybin influence support for psilocy...

Background and Objectives: Substance use disorders (SUDs) affect millions worldwide. Despite increasing drug use, treatment options remain limited. Psychedelic-assisted therapy (PAT), integrating psychedelic substances with psychotherapy, offers a promising alternative by addressing underlying neural mechanisms. Materials and Methods: This review's purpose i...
There is notable controversy about the role of psychotherapy in clinical trials of psychedelic-assisted therapy (PAT). This heated and perpetually evolving debate informs questions such as how much therapy should accompany a psychedelic intervention (Marseille et al., 2022), what type of therapy most effectively complements psychedelic administration (Cavarr...
Psilocybin, a psychedelic compound in “magic” mushrooms, has promise as a novel treatment for psychiatric disorders, many of which are more prevalent in females and have onsets during adolescence. However, there is a lack of research about how factors such as sex and age affect responses to psilocybin, as well as potential safety concerns with developmental ...
This scoping review examines the emerging evidence for psilocybin-assisted therapy (PAP) in treating trauma-related disorders such as posttraumatic stress disorder (PTSD), depression, and persistent post-concussion symptoms (PPCS), with specific implications for intimate partner violence (IPV)-related brain injury and PTSD. Guided by PRISMA-ScR methodology, ...
Serotonin receptors, also known as 5-hydroxytryptamine (5-HT) receptors, are a diverse family of G protein-coupled and ligand-gated ion channel receptors that mediate the physiological effects of the neurotransmitter serotonin. These receptors are widely distributed throughout the central and peripheral nervous systems, where they regulate numerous processes...
Although studies of psychedelic-assisted psychotherapy are accumulating, there is no consensus regarding best practice of the psychotherapeutic component. In this systematic review, we summarised the quality of reporting on psychological interventions in research about psychedelic treatments. The design followed PRISMA guidelines and was preregistered in PRO...
This study aims to investigate the effects of oral psilocybin on OCD symptomatology and provide the first evidence of the neural mechanism that may mediate psilocybin's purported therapeutic effects on OCD. Aim 1: To investigate the effects of psilocybin on OCD symptomatology. OCD symptom severity will be assessed before treatment and 24 and 48 hours after t...
Background: Negative perceptions of psilocybin and challenges of participant enrollment may represent barriers to conducting a randomized controlled trial examining psilocybin for chronic neuropathic pain. Aim: Prior to trial initiation, we aimed to examine patient attitudes toward the trial via a prospective preference assessment. Methods: Twenty-six patien...
Different study designs of psychedelic trials may impact the blinding and expectance, leading to biased treatment effects. This study aimed to examine the association between antidepressant efficacy and study designs in psychedelic trials. Six databases were systematically searched. Eligible trials were required to investigate the efficacy of psychedelics (p...
OBJECTIVES: Promising studies show that psilocybin-assisted therapy relieves existential distress in patients with serious illnesses, a difficult condition to treat with current treatment options. There is growing interest in this therapy in palliative care. Canada recently amended its laws to allow physicians to request psilocybin for end-of-life distress. ...
Over the past decade there has been a surge in interest in placebo-controlled trials using non-classical 3,4-methylenedioxymethamphetamine (MDMA) and classical psychedelics such as psilocybin, lysergic acid diethylamide (LSD) and N,N-dimethyltryptamine (DMT) to treat neuropsychiatric disorders. However, the success and reliability of these trials depend on t...
Abstract Ketamine and psilocybin show potential as therapies for various mental illnesses, including major depressive disorder. However, further investigation into their neural mechanisms is required to understand their effects on the brain. By combining computational modelling with electroencephalography (EEG), we examine the effects of ketamine and psilocy...
