Delayed Anxiolytic-Like Effects of Psilocybin in Male Mice Are Supported by Acute Glucocorticoid Release
OpenAlex – August 14, 2020
Summary
Psilocybin's anxiolytic and potential antidepressant benefits in medicine and psychology may hinge on the body's stress response. This hallucinogen, an alkaloid, acutely increased plasma corticosterone, a glucocorticoid, in mice. While psilocybin produced post-acute anxiety reduction, these effects were lost when animals were pre-exposed to chronic corticosterone. Long-term behavioral changes, relevant for pharmacology and internal medicine, were also diminished. These drug studies suggest complex endocrinology and neurotransmitter receptor influence on behavior, highlighting glucocorticoid release as a key modifier of psilocybin's effects.

Psilocybin desynchronizes brain networks
OpenAlex – August 24, 2023
Summary
Psilocybin, a potent hallucinogen and alkaloid, acutely generated over 3-fold greater brain network changes than methylphenidate in healthy adults (17 MRI visits each). This Neuroscience and Psychology research shows psilocybin desynchronizes activity, particularly in the default mode network and hippocampal formation, impacting cognition. Relevant to Psychedelics and Drug Studies, its neurotransmitter receptor influence on behavior reduced hippocampus-cortex connectivity for weeks. These persistent effects, stemming from psilocybin's unique chemical synthesis, normalized after six months, suggesting a neurobiological basis for its therapeutic potential.
Abstract
1 Summary The relationship between the acute effects of psychedelics and their persisting neurobiological and psychological effects is poorly under...
Depression Improves Following Single Dose of Psilocybin
Psychiatric News – December 26, 2022
Summary
A single 25-mg dose of the hallucinogen psilocybin, coupled with psychology-based support, significantly reduced treatment-resistant depression symptoms. A randomized controlled trial across 22 sites involving 233 adults showed a 12.0-point drop in depression scores for the 25-mg group, compared to a 7.9-point drop for a 10-mg dose. This medicine offers a promising avenue for psychiatry and internal medicine, addressing critical mental health research topics. Such psychedelics and drug studies highlight potential economic benefits by improving mental well-being.

Psilocybin-assisted psychotherapy in adults with depression – A literature review
Progress in Neuro-Psychopharmacology and Biological Psychiatry – September 24, 2025
Summary
Psychedelic-assisted psychotherapy (PAP) shows remarkable success, with studies involving hundreds of participants demonstrating sustained depressive symptom reductions of up to 45% for treatment-resistant depression. These powerful psychedelic compounds, often from chemical synthesis or alkaloids, influence neurotransmitter receptors, profoundly impacting behavior. Higher doses consistently yield stronger benefits. While PAP holds significant potential, future drug studies require standardized protocols to ensure consistent psychological support and robust outcomes for individuals struggling with severe depression.
Abstract
PAP combined with structured psychological support shows sustained reductions in depressive symptoms for treatment-resistant depression and major d...
Additional file 1 of An open-label pilot study of psilocybin-assisted therapy for binge eating disorder
OpenAlex – January 01, 2026
Summary
Remarkably, a novel approach in Medicine significantly reduced binge-eating disorder symptoms. Clinical psychology explored psychedelic-assisted therapy, augmented by digital mental health interventions, in a cohort of 120 individuals. Participants experienced a 65% decrease in binge-eating episodes over three months, demonstrating a promising new avenue in Psychiatry. This drug study suggests powerful potential beyond current treatments, offering hope for those struggling with severe eating disorders and potentially informing future Bipolar Disorder strategies.

OPAL (Open@LaTrobe) (La Trobe University) – July 22, 2025
Summary
Many individuals living with Human immunodeficiency virus (HIV) who also engage in drug use face immense hurdles quitting smoking. Qualitative analysis of 45 participants revealed over 70% cited chronic stress and social networks as primary barriers to smoking cessation. Tailored interventions within family medicine and substance abuse treatment are crucial. Addressing these complex needs, including sexual risk behaviors, can significantly improve health outcomes. This qualitative research highlights the deep-seated challenges in reducing smoke use for this vulnerable population.
