Impact of Psilocybin on Motor Function in Healthy Participants: A Phase 1, Randomised, Triple-Blind, Dose-Finding Study

CNS Drugs August 7, 2026 Chiranth Bhagavan, Olivia Carter, Glenn Nielsen et al.

BACKGROUND: Psychedelics exert widespread effects on brain activity, but their impact on motor function is unclear. This is clinically relevant given the emerging interest in psychedelic-assisted physical therapy for disorders of motor function. This study examined the feasibility and safety of administering movement tasks following low-to-moderate doses of psilocybin in healthy volunteers....

Ten practical suggestions for setting up a psychedelic study.

Journal of Psychopharmacology June 16, 2026 Alice Caulfield, Matthew Butler, Mitul A. Mehta

The therapeutic potential of psychedelics is currently being explored in a range of neuropsychiatric conditions. Nevertheless, their designation as Schedule 1 substances causes substantial regulatory and economic barriers to research. Rigorous human mechanistic studies are required to address the critical knowledge gaps surrounding the mechanisms underlying the putative treatment effects of...

Psilocybin-assisted physiotherapy for refractory motor functional neurological disorder: protocol for a randomised dose-comparison pilot study

Acta Neuropsychiatrica November 4, 2025 Chiranth Bhagavan, Alexander Bryson, Olivia Carter et al. 4 citations

Abstract Background: Motor functional neurological disorder (FND) is a common illness associated with significant functional impairment. There are no effective pharmacotherapies, and despite the early promise of physiotherapy studies, many suffer disabling symptoms in the long term. There is a theoretical rationale for combining psychedelics with physiotherapy; however, the potential benefit of...

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

Wellcome Open Research April 22, 2025 Matthew Butler, Catherine Bird, Carolina Maggio et al. 3 citations

Background 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...

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...

A closer look at yoga nidra- early randomized sleep lab investigations.

Journal of Psychosomatic Research March 2023 Erica Sharpe, Matthew Butler, Jesse Clark-Stone et al.

We aimed to examine trial feasibility plus physiological and psychological effects of a guided meditation practice, Yoga Nidra, in adults with self-reported insomnia. Twenty-two adults with self-reported insomnia were recruited to attend two visits at our research center. At Visit 1 (V1), participants were asked to lie quietly for ninety minutes. The primary outcome was change in...

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...

Views on Using Psychoactive Substances to Self-Manage Functional Neurological Disorder: Online Patient Survey Results

The Journal of Neuropsychiatry and Clinical Neurosciences May 17, 2022 Matthew Butler, Mathieu Seynaeve, Abigail Bradley‐Westguard et al. 6 citations

Objective: Functional neurological disorder (FND) causes a high burden of disability and distress. Although it is a common disorder, there is a pressing need for improved access to evidence-based treatments. With difficulties in finding effective treatment, some people with FND may seek alternative means of symptom relief, such as legal and illicit psychoactive substances, although the...

Ceremonial Ayahuasca in Amazonian Retreats—Mental Health and Epigenetic Outcomes From a Six-Month Naturalistic Study

Frontiers in Psychiatry June 9, 2021 Simon Ruffell, Nige Netzband, WaiFung Tsang et al. 74 citations

Ayahuasca is a natural psychoactive brew, used in traditional ceremonies in the Amazon basin. Recent research has indicated that ayahuasca is pharmacologically safe and its use may be positively associated with improvements in psychiatric symptoms. The mechanistic effects of ayahuasca are yet to be fully established. In this prospective naturalistic study, 63 self-selected participants took...
