We quantify cellular- and circuit-resolution neural network dynamics following therapeutically relevant doses of the psychedelic psilocybin. Using chronically implanted Neuropixels probes, we recorded local field potentials (LFP) alongside action potentials from hundreds of neurons spanning infralimbic, prelimbic and cingulate subregions of the medial prefro...
Background: Current trauma treatment options often fail to meet patients' needs. Despite the availability of established interventions, many trauma treatments fail to adequately meet patients' needs. In parallel, there has been renewed scientific and public interest in the therapeutic potential of psychedelics and related compounds, accompanied by increasing...
Objective: Hallucinogen-persisting Perception Disorder (HPPD) is a rare condition characterized by the re-experiencing of one or more perceptual symptoms that an individual experienced while intoxicated with a hallucinogenic substance when the individual is sober. While there are several case reports of HPPD in adult patients, there is a scarcity of document...
IMPORTANCE: Psilocybin-assisted psychotherapy may offer a novel approach to treating depression, anxiety, and existential distress in individuals with life threatening illnesses, where current treatments show limited efficacy. OBJECTIVE: To evaluate the efficacy and safety of psilocybin-assisted psychotherapy versus active placebo and psychotherapy in adults...
Treatment resistant depression (TRD) is frequently encountered in clinical practice. The lack of response of the condition to conventional medications and augmentation strategies has spawned the search for novel treatment approaches. Psychedelic medications used in conjunction with intensive psychotherapy, so-called psychedelic-assisted psychotherapy (PAP), ...
Introduction: Psilocybin, a serotonergic psychedelic, has shown therapeutic potential in treating mental health disorders by, amongst the many effects, promoting neuroplasticity and reorganising functional connectivity across cortical and subcortical networks involved in emotion and cognition. Veterans with traumatic brain injuries (TBI) often experience chr...
Depression prevalence is markedly elevated in oncological patients, particularly among head and neck cancer (HNC) cohorts, who face twice the prevalence of major depressive disorder (MDD) compared to other cancer populations. MDD in this context independently predicts poorer clinical outcomes and increased morbidity. HNC management often involves acute surgi...
BACKGROUND: Recent regulatory changes in Australia have approved 3,4-methylenedioxymethamphetamine for treating post-traumatic stress disorder and psilocybin for treatment-resistant depression. However, limited data exists on Australian mental healthcare providers' attitudes, knowledge and readiness to implement with psychedelic-assisted psychotherapy. METHO...
Background Recent studies have suggested that psychedelics such as lysergic acid diethylamide (LSD) and psilocybin might benefit patients with mental illness. This revival calls for revisiting the field’s past experiences with these agents. From 1960 to 1973, many patients were treated with LSD and/or psilocybin at the Department of Psychiatry at Frederiksbe...
Psychedelic-assisted therapies and ketamine are two modalities gaining attention in psychiatry for treating conditions such as depression, PTSD, and substance use disorders. However, perceptions of these treatments vary globally. This study explores the familiarity, attitudes, and perceptions of Jordanian physicians and medical students toward psychedelic su...
BACKGROUND: Obsessive-compulsive disorder (OCD) is a common and disabling condition. A large proportion of patients fail to respond to first-line treatment with serotonin reuptake inhibitors either selective serotonin reuptake inhibitors (SSRIs) or clomipramine. Preliminary evidence suggests psilocybin, a serotonin receptor agonist, might be efficacious. We ...
Psychoactive substances are compounds that can influence perception, consciousness, cognition, and emotions. The psychoactive substances caffeine, nicotine, cannabis, and psilocybin all originate from natural sources and can be used without complex processing or synthesis. Their natural availability has contributed to a long-standing history of human use and...
BackgroundDespite a limited evidence base to inform clinicians, Australia has adopted a national approach in rescheduling psilocybin and MDMA as clinical therapies for treatment-resistant depression (TRD) and post-traumatic stress disorder (PTSD), respectively.PurposeThis paper explores clinical research domains warranting further investigation through outli...
Background Ketamine exerts potent but transient antidepressant effects in treatment-resistant depression (TRD). Combinations of ketamine and psychotherapy have attracted interest, but no trial has investigated a psychedelic model of ketamine-psychotherapy for TRD to our knowledge. Aims This secondary analysis of a randomised clinical trial (RCT) explores the...
Psilocybin is among the most extensively studied psychedelics, with previous research suggesting its potential therapeutic role in suicide prevention. However, the precise mechanisms through which psilocybin may aid in suicide prevention remain unclear. This study thus employed network pharmacology and molecular docking tools to explore the mechanisms by whi...
Depression and anxiety are disabling and high incidence mental disorders characterized by phenotypic heterogeneity. Currently available treatments show severe limitations. Thus, there is an urgent need for effective treatments in this population. In the search for novel rapid-acting antidepressants, the psychedelic psilocybin has emerged as a promising thera...
This paper provides an overview of psychedelic research at the Mayo Clinic in the 1950s and 1960s, focusing on methods, objectives, findings, and ethical practices. We highlight instances where researchers prioritized scientific progress over the autonomy, safety, and equitable treatment of research subjects, and discuss this history in the context of ongoin...
OBJECTIVES: Psychedelics may be promising treatments for substance use disorders (SUD). This study aims to understand how individuals with alcohol use disorder (AUD), opioid use disorder (OUD), and psychiatric disorders perceive and experience psychedelics for both nonmedical and medical use. METHODS: Data for this cross-sectional survey study were collected...
