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...
RATIONALE: Anecdotal evidence suggests that psychedelic researchers often have personal experiences with psychedelic substances. While such experiences may benefit research, concerns have been raised about potential biases and "excessive enthusiasm." However, the prevalence of personal experiences, their perceived relevance, and their association with opinio...
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...
Psilocybin, a compound found in Psilocybe mushrooms, is emerging as a promising treatment for neurodegenerative and psychiatric disorders, including major depressive disorder. Its potential therapeutic effects stem from promoting neuroprotection, neurogenesis, and neuroplasticity, key factors in brain health. Psilocybin could help combat mild neurodegenerati...
Use of selective serotonin reuptake inhibitor (SSRI) antidepressants has been associated with reduced intensity of emotional experience. Conversely, some research has shown that use of psilocybin in patients with depression leads to an increase in responsiveness to emotional face stimuli, suggesting that the psychedelic generates a transient elevation in moo...
Interest in and use of hallucinogens appears to be growing in the United States, yet less is known about the use of multiple hallucinogens. The aims of this study are to characterize subgroups of lifetime hallucinogen use and to identify sociodemographic correlates of these subgroups. Latent class models were fit using 2021-2022 National Survey on Drug Use a...
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...
Abstract Background We have designed a novel psychedelic-derived compound (HBL20017) characterized by high functional efficacy at 5-HT2A, 5-HT1A, and 5-HT2C receptors. We assessed its hallucinogenic properties and its potential for OCD treatment on the marble burying test (MBT) and in mice homozygous for deletion of the Synapse Associated Protein 3 (SAPAP3) ...
Abstract Background Major depressive disorder (MDD) is a multifactorial and heterogeneous disorder that affects around 280 million individuals worldwide, with approximately 80 million experiencing treatment-resistant depression (TRD). Neuronal hypotrophy and axon hypomyelination in the prefrontal cortex (PFC) are hallmark features of MDD, highlighting the ne...
Depression, a common mental disorder, affects people at different stages of life.Classic antidepressant treatment is generally effective, however, it is prolonged.Nonetheless, numerous patients who undergo various classic antidepressant therapies still suffer from depression.Therefore, the search for novel medications is essential.In this review, we explore ...
BACKGROUND AND AIMS: Psilocybin has emerged as a potential treatment for alcohol use disorder (AUD), but early efficacy data are inconsistent. Depression following alcohol detoxification significantly increases the risk of relapse. This pilot study aimed to evaluate the feasibility, acceptability, and preliminary efficacy of psilocybin-assisted psychotherapy...
BACKGROUND: People with HIV (PWH) are disproportionately affected by cigarette use, with a 40 - 70% prevalence rate. Although many express a strong interest in quitting, many PWH who smoke experience lower cessation rates with traditional treatments, in part due to their comorbid anxiety and depressive symptoms. Psilocybin, a classic psychedelic referred to ...
The serotonergic hallucinogen psilocybin has shown potential as a treatment for psychiatric conditions like alcohol use disorder (AUD) and depression in clinical studies. Epigenetic mechanisms, including DNA methylation, are hypothesized to contribute to its lasting therapeutic benefits. In this exploratory study, we present the first methylome-wide analysis...
This study examines the relationship between psilocybin reforms and usage patterns of prevalent psychedelics in the United States. Given decriminalization efforts in several cities and legalization in Oregon, the author analyzes drug use panel data from University of Michigan's Monitoring the Future project to assess changes in self-reported use of psilocybi...
Background Classic psychedelics, such as psilocybin and LSD, evoke certain kinds of altered states of consciousness. Specific features of the experience, such as its allegedly ineffable nature, have been discussed as posing challenges to the informed consent process. A growing call for tailored informed consent documents (ICDs) in the psychedelic bioethics l...
Perception of visual contrast depends on the surrounding spatial context. Typically, the salience of a central target is reduced by a high contrast surrounding stimulus, an effect known as surround suppression. Although this phenomenon is well-studied, the role of specific neurotransmitter systems during surround suppression in human vision remains unclear. ...
