The serotonin 1B receptor is required for some of the behavioral effects of psilocybin in mice.
Recent studies highlight the promising use of psychedelic therapies for psychiatric disorders, including depression. The persisting clinical effects of psychedelics such as psilocybin are commonly attributed to activation of the serotonin 2A receptor (5-HT2AR) based on its role in the acute hallucinatory effects. However, the active metabolite of psilocybin ...
Psilocybin Treatment as an Adjunct to Cognitive Behavioral Therapy for Eating Disorders: Therapeutic Rationale & Considerations for Protocol Development
Eating disorders (ED) remain challenging to treat, with high dropout and low remission rates in cognitive-behavioral therapy for EDs (CBT-ED). Psilocybin treatment (PT) demonstrates therapeutic potential to enhance CBT-ED by exerting several neurobiological, psychological, and experiential effects (e.g., antidepressant, neuroplasticity, emotional openness) t...
Psilocybin reporting in media (PRiMe) for the treatment of depression.
ObjectivesInterest in psilocybin as a treatment for depression has risen over the past decade, fuelled by promising clinical trials and a rapidly evolving regulatory landscape. Media coverage plays a critical role in shaping public perceptions, yet little is known about how psilocybin is portrayed in global anglophone online news for the treatment of depress...
Psilocybin-assisted therapy for individuals with palliative care needs: A systematic review of safety and efficacy.
BackgroundPalliative Care is concerned with relieving suffering and improving the quality of life of patients and their families. Currently, questions arise about how to provide patients with good end-of-life care. There has been increasing interest in the beneficial effects of using psilocybin-assisted therapy in patients with severe chronic illnesses near ...
Which Psychotherapy Model Should be Used in Psilocybin Treatment for Depression?
ObjectiveUnipolar and bipolar depression severely impact millions of individuals worldwide, with a significant subset of cases remaining unresponsive to conventional treatments. Psilocybin-assisted psychotherapy (PAP) has demonstrated therapeutic efficacy; however, the optimal psychotherapeutic approach remains undefined, ranging from unstructured models roo...
Psilocybin in the real world: Regulatory, ethical, and operational challenges in Australia's clinical landscape.
Australia's reclassification of psilocybin as a Schedule 8 substance for treatment-resistant depression represents a significant shift in psychiatric policy. While this regulatory change positions Australia as a global leader in psychedelic medicine, its implementation has revealed substantial challenges. This article critically examines the regulatory, ethi...
Breaking the chains of depression: A systematic review and meta-analysis of psilocybin therapy.
Psilocybin, a naturally occurring hallucinogenic substance present in certain mushrooms, has drawn growing attention as a therapeutic breakthrough for several mental and psychiatric conditions. Psilocybin originated in spiritual and cultural traditions and has become the focus of extensive scientific research. This meta-analysis and systematic review aggrega...
Advances in Psychedelic Therapeutics: Multimodal Iboga Analogs, EEG-Guided Psilocybin Dosing, and Optimized Harmine-DMT Formulations.
Emerging psychedelic therapeutics increasingly rely on mechanistic precision, receptor selectivity, and pharmacokinetic control. Recent inventions introduce simplified iboga analogs with tunable polypharmacology, real-time EEG biomarkers that individualize psilocybin dosing, and standardized harmine-DMT ratios with high bioavailability. Together, these innov...
Psychedelic experiences elicited by serotonergic psychedelics: Molecular mechanisms and functional connectivity changes in the brain.
Classical psychedelics, like lysergic acid diethylamide (LSD), N,N-dimethyltryptamine (DMT), and psilocybin, can alter perception, emotion, and cognition, and have shown promise as 're-purposed' treatments for some psychiatric disorders. Recent trials have, e.g., demonstrated rapid and sustained symptom relief in treatment-resistant depression. While promisi...
Psilocybin-assisted psychotherapy for treatment-resistant obsessive-compulsive disorder: protocol for an open-label pilot study.
BackgroundObsessive-compulsive disorder (OCD) is a debilitating mental disorder commonly treated with selective serotonin reuptake inhibitors, atypical antipsychotic augmentation and cognitive-behavioural therapy. However, up to 60% of people with OCD do not respond to these treatments. Therefore, a novel intervention, psilocybin-assisted psychotherapy (PAP)...
Regional specificity of the cingulate cortex thickness association with the intensity of psilocybin experience: a replication study.
RATIONALE: Individual variability in psilocybin response is a major challenge for psychedelic-assisted therapy, with structural brain features potentially serving as predictive biomarkers. (Lewis et al. Biomedicines 8(2):34 2020) reported that rostral anterior cingulate cortex thickness predicted emotional experiences under psilocybin, suggesting cortical mo...
Real-World Psilocybin Therapy for Treatment-Resistant Depression: a Retrospective Observational Study
Abstract Psilocybin has demonstrated promising antidepressant effects in depression and treatment-resistant depression (TRD) in controlled clinical trials. However, its effectiveness and safety in real-world therapeutic settings remain largely unknown. Although psilocybin is not yet approved as an antidepressant treatment, Switzerland’s unique legal framewor...
The Psychedelic Psilocin Suppresses Activity of Central Amygdala Corticotropin-Releasing Factor Receptor 1 Neurons and Decreases Ethanol Drinking in Female Mice.
Alcohol use disorder (AUD) is a highly prevalent disorder with limited therapeutic options. The central amygdala (CeA) is a critical brain region as dysregulation within the CeA and the corticotropin-releasing factor (CRF) system are associated with AUD pathology. CeA CRF1 receptors regulate alcohol drinking and have served as a therapeutic target in alcohol...
Acute and post-dosing effects of single-dose psilocybin for obsessive-compulsive disorder in a randomized, double-blind, placebo-controlled trial: an interpretative phenomenological analysis.
IntroductionThe subjective effects of psilocybin on obsessive-compulsive disorder (OCD) are under-explored. Therefore, we conducted a qualitative study of participant experiences from the first randomized placebo-controlled trial of single-dose psilocybin combined with unstructured and non-directive support for individuals with treatment-refractory OCD. Our ...
Stepping back into life: How Psychedelic Assisted Psychotherapy transforms the way of life of the terminally ill.
This qualitative study of how successful Psychedelic Assisted Psychotherapy (PAP) transforms the way of life of terminally ill subjects provides new knowledge for researchers and clinicians contemplating its use. Using an interpretive phenomenological approach (IPA) and interviews with subjects before and after PAP from a recent randomised control trial, we ...
Psilocybin in Alcohol Use Disorder Maintains Abstinence Efficacy: A Scoping Review
Alcohol use disorder is a psychiatric condition characterized by excessive alcohol consumption. The drugs that are used to treat it often fail to prevent relapse. At the same time, psilocybin is increasingly being investigated for the treatment of various substance use disorders. This review aims to evaluate the results of the most recent clinical trials ass...
Psilocybin in late-life mental health: Addressing depression, loneliness, and existential anxiety.
The global demographic shift toward aging populations has intensified the need for innovative therapeutic interventions targeting late-life mental health conditions, notably depression, loneliness, and existential distress. Traditional pharmacological treatments often exhibit limited efficacy and poor tolerability in older patients, primarily due to age-rela...
Psilocybin induces sex- and context-specific recruitment of the stress axis.
Following decades of prohibition, psychedelic drugs have reemerged as promising therapeutics for stress-related conditions, including depression and post-traumatic stress disorder. Still, their impact on stress-related brain regions and the hypothalamic-pituitary-adrenal (HPA) axis remains unclear. This work explores the acute effects of psilocybin on the pr...
