Low‐dose psilocybin in short‐lasting unilateral neuralgiform headache attacks: results from an open‐label phase Ib ascending dose study

Headache The Journal of Head and Face Pain September 20, 2024 James Rucker, Sadie Hambleton, Catherine Bird et al. 12 citations

Abstract Background Short‐lasting unilateral neuralgiform headache attacks (SUNHA) are trigeminal autonomic cephalalgias that feature intense and recurrent paroxysms of pain and autonomic symptoms. Many patients are left with debilitating symptoms despite best‐available treatment. Psychedelics, such as the serotonin 2A partial agonist psilocybin, have shown promise in related disorders such as...

Psilocybin and Motor Function: A Triple‐Blind, Dose‐Finding Study in Healthy Participants

Psychiatric Research and Clinical Practice July 23, 2024 Chiranth Bhagavan, Richard Kanaan, Olivia Carter et al. 2 citations

Background There has been a resurgence of research into the potential therapeutic benefits of psychedelics for neuropsychiatric disorders. Classic psychedelics, such as psilocybin, exert complex effects on higher cognitive functions such as perception and awareness, but their impact on motor function remains unexplored. Moreover, there is a theoretical rationale for using psychedelics to...

In Table 3, titled “Psilocybin studies on depressive disorders,” specifically in the fourth row related to the study conducted by Carhart-Harris et al. (2016), the main results column inaccurately presented the Cohen's d figure, which included data from Carhart-Harris et al. (2018) that...

Probing the functional magnetic resonance imaging response to psilocybin in functional neurological disorder (PsiFUND): study protocol.

Wellcome Open Research 2024 Matt Butler, Catherine Bird, Carolina Maggio et al. 4 citations

Functional neurological disorder (FND) is a common cause of neurological symptoms including seizures and movement disorders. It can be debilitating, is associated with high health and social care costs, and can have a poor prognosis. Functional magnetic resonance imaging (fMRI) has suggested FND is a multi-network disorder. Converging evidence suggests that other mechanisms including...

Evidence versus expectancy: the development of psilocybin therapy

BJPsych Bulletin May 29, 2023 James Rucker 9 citations

Summary Although the development of psilocybin therapy has come as a surprise to many, modern research with the drug has been ongoing for 25 years. Psilocybin therapy is composed of psilocybin dosing sessions embedded within a wider process of psychoeducation, psychological support and integration. Early phase clinical trial evidence is promising, particularly for treatment-resistant...

Single-Dose Psilocybin for a Treatment-Resistant Episode of Major Depression.

The New England journal of medicine November 3, 2022 Guy M. Goodwin, Scott T Aaronson, Oscar Alvarez et al. 1,095 citations

Psilocybin is being studied for use in treatment-resistant depression. In this phase 2 double-blind trial, we randomly assigned adults with treatment-resistant depression to receive a single dose of a proprietary, synthetic formulation of psilocybin at a dose of 25 mg, 10 mg, or 1 mg (control), along with psychological support. The primary end point was the change from baseline to week 3 in the...

Expectancy in placebo-controlled trials of psychedelics: if so, so what?

Psychopharmacology September 5, 2022 Matthew Butler, Luke A. Jelen, James Rucker 91 citations

Modern psychedelic research remains in an early phase, and the eventual introduction of psychedelics into clinical practice remains in doubt. In this piece, we discuss the role of blinding and expectancy in psychedelic trials, and place this in a broader historical and contemporary context of blinding in trials across the rest of healthcare. We suggest that premature and uncritical promotion...

Psychedelics, Mystical Experience, and Therapeutic Efficacy: A Systematic Review

Frontiers in Psychiatry July 12, 2022 Kwonmok Ko, Gemma Knight, James Rucker et al. 296 citations

The mystical experience is a potential psychological mechanism to influence outcome in psychedelic therapy.

CNS Drugs July 20, 2021 Vera Miriam Ludwig, Cathrin Sauer, Allan H. Young et al. 23 citations

(Es)ketamine and monoamine oxidase inhibitors (MAOIs), e.g., tranylcypromine, are therapeutic options for treatment-resistant major depression. Simultaneous administration is currently not recommended because of concern about hypertensive crises. Our objective was to evaluate whether changes in systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) during esketamine...

The mechanistic effects of ayahuasca are yet to be fully established. In this prospective naturalistic study, 63 self-selected participants took...

Psilocybin: From Serendipity to Credibility?

Frontiers in Psychiatry April 21, 2021 James Rucker, Allan H. Young 40 citations

Psilocybin has a long history of non-medical use and some seem to infer from this that it has therapeutic utility. Early phase clinical trials with psilocybin are encouraging, but suggest only that larger, multicentre trials are required. These are ongoing but will take many years to complete. Meanwhile, retreat centers offering paid experiences with psilocybin truffles have opened in some...
