Psilocybin therapy for adult females with anorexia nervosa: pilot study.

Br J Psychiatry July 8, 2026 Hannah Douglass, Meg J. Spriggs, Kate Godfrey et al.

Background Anorexia nervosa is a debilitating eating disorder with high mortality and chronicity rates owing to the paucity of effective existing treatments. Several clinical trials using psilocybin therapy have demonstrated therapeutic efficacy and safety in psychiatric conditions, including anorexia nervosa. Aims This study aimed to further assess the safety, feasibility and potential...

Human brain changes after first psilocybin use.

Nature Communications May 5, 2026 T Lyons, M Spriggs, L Kerkelä et al. 19 citations

Psychedelics have robust effects on acute brain function and long-term behavior but whether they also cause enduring functional and anatomical brain changes is largely unknown. In an exploratory, placebo-controlled, within-subjects, electroencephalography (EEG), and magnetic resonance imaging (MRI) study in 28 healthy, entirely psychedelic-naive participants, anatomical and functional brain...

Neuroplasticity and Psychedelics: a comprehensive examination of classic and non-classic compounds in pre and clinical models

arXiv Preprint Archive November 29, 2024 Claudio Agnorelli, Meg J. Spriggs, Kate Godfrey et al. 32 citations

Neuroplasticity, the ability of the nervous system to adapt throughout an organism's lifespan, offers potential as both a biomarker and treatment target for neuropsychiatric conditions. Psychedelics, a burgeoning category of drugs, are increasingly prominent in psychiatric research, prompting inquiries into their mechanisms of action. Distinguishing themselves from traditional medications,...

Body mass index (BMI) does not predict responses to psilocybin

Journal of Psychopharmacology November 14, 2022 Meg J. Spriggs, Bruna Giribaldi, Taylor Lyons et al. 15 citations

Background: Psilocybin is a serotonin type 2A (5-HT 2A ) receptor agonist and naturally occurring psychedelic. 5-HT 2A receptor density is known to be associated with body mass index (BMI), however, the impact of this on psilocybin therapy has not been explored. While body weight-adjusted dosing is widely used, this imposes a practical and financial strain on the scalability of psychedelic...

Study Protocol for “Psilocybin as a Treatment for Anorexia Nervosa: A Pilot Study”

Frontiers in Psychiatry October 20, 2021 Meg J. Spriggs, Hannah Douglass, Rebecca J. Park et al. 78 citations

Background: Anorexia nervosa (AN) is a serious and life-threatening psychiatric condition. With a paucity of approved treatments, there is a desperate need for novel treatment avenues to be explored. Here, we present (1) an overview of the ways through which Public Patient Involvement (PPI) has informed a trial of psilocybin-assisted therapy for AN and (2) a protocol for a pilot study of...

Psychedelics and health behaviour change

Journal of Psychopharmacology May 29, 2021 Pedro J. Teixeira, Matthew W. Johnson, Christopher Timmermann et al. 87 citations

Healthful behaviours such as maintaining a balanced diet, being physically active and refraining from smoking have major impacts on the risk of developing cancer, diabetes, cardiovascular diseases and other serious conditions. The burden of the so-called ‘lifestyle diseases’—in personal suffering, premature mortality and public health costs—is considerable. Consequently, interventions designed...
