Background: Advanced Alzheimer's disease (AD) is generally regarded as a stage of irreversible functional decline. Psilocybin is known to transiently alter large-scale brain network dynamics and to induce plasticity-related mechanisms in preclinical models, yet clinical data in advanced dementia remain lacking. Case presentation: We report the case of an oct...
We propose a first-of-its-kind open-label clinical trial to investigate the feasibility, tolerability, and safety of administering psilocybin in autistic adults with treatment-resistant depression (TRD). In this study, 20 participants (intellectually able and fluent-speech adults) with autism and co-occurring TRD will receive around 20 hours of manualized ps...
Abstract Background: This case describes a substance-induced manic episode with psychotic features in which interaction with an AI (artificial intelligence) chatbot appeared to corroborate and reinforce the patient’s delusional thought content and to contradict medical advice. Excerpts from the patient’s interactions with the AI chatbot provide novel clinica...
This Phase 2a clinical trial is an open-label, single-group, within-subjects pilot study designed to evaluate the safety, feasibility, and preliminary efficacy of psilocybin as a therapeutic intervention for adults with developmental stuttering. This pilot study will assess whether further research to explore the potential benefits of psilocybin-assisted the...
Serotonergic psychedelics have shown promise in clinical trials for treating an array of mental health disorders, including depression, anxiety, and post-traumatic stress disorder. Despite these findings, our understanding of how these drugs mechanistically exert their therapeutic effects remains incomplete. While researchers have regularly employed rodent p...
Psychoactive substances used for recreational purposes have mind-altering effects, but systematic evaluation of these effects is largely limited to self-reports. Automated analysis of expressed language (speech and written text) using natural language processing (NLP) tools can provide objective readouts of mental states. In this pre-registered systematic re...

A previously healthy adolescent presented to the emergency department with an abrupt onset of altered mental status and abnormal behaviour, including shaking of the extremities, rocking back and forth, and non-sensical speech, after ingestion of chocolate that contained psilocybin. Neurological
Context: Measuring therapeutic connection during psilocybin-assisted therapy is essential to understand underlying mechanisms, inform training, and guide quality improvement. Purpose: To evaluate the feasibility of directly observing indicators of therapeutic connection during psilocybin administration encounters. Methods: We evaluated audio and video data f...
RationaleSerotonergic psychedelics are being studied as novel treatments for mental health disorders and as facilitators of improved well-being, mental function, and creativity. Recent studies have found mixed results concerning the effects of low doses of psychedelics ("microdosing") on these domains. However, microdosing is generally investigated using ins...

BackgroundWe draw on both interdisciplinary enhancement substance use research and critical drug studies scholarship to reconceptualise enhancement substance use. Our critical discourse approach illuminates how a variety of substances are positioned as tools for self-improvement. In reconceptualising enhancement substance use, we ask what different substance...
BackgroundNatural speech analytics has seen some improvements over recent years, and this has opened a window for objective and quantitative diagnosis in psychiatry. Here, we used a machine learning algorithm applied to natural speech to ask whether language properties measured before psilocybin for treatment-resistant can predict for which patients it will ...
