Research Square (Research Square) February 23, 2024 Ari Brouwer, Joshua K. Brown, Earth Erowid et al. 5 citations

Abstract Psychedelic therapy has the potential to become a revolutionary and transdiagnostic mental health treatment, yielding enduring benefits that are often attributed to the experiences that coincide with peak psychedelic effects. However, there may be an underrecognized temporal structure to this process that helps explain why psychedelic and related altered states of consciousness can...

Research Square (Research Square) January 4, 2024 Laetitia Vanderijst, Felix Hever, Anne Buot et al.

Abstract Background: A significant number of individuals with alcohol use disorder remain unresponsive to currently available treatments, which calls for the development of new alternatives.

Abstract Background Depression is a major global health challenge, affecting over 300 million people worldwide.

A quantitative textual analysis of the subjective effects of ayahuasca in naive users with and without depression

Research Square (Research Square) August 23, 2023 Lucas Villar Magalhães da Cruz, Bheatrix Bienemann Favero, Fernanda Palhano-Fontes et al.

Abstract Ayahuasca is a brew with psychoactive properties that has been used as an entheogen for centuries, with more recent studies suggesting it is a promising treatment for some clinical disorders. Although there is an emerging scientific literature on its effects, to the best of our knowledge no study has explored the self-reported experiences of first-time ayahuasca users with quantitative...

“Why would you open someone’s brain up?” Lived experience insights inform a psilocybin-assisted psychotherapy treatment manual for body image disturbance

Research Square (Research Square) July 27, 2023 Claire Finkelstein, Olivia Soha, Alana Roy et al. 2 citations

Abstract Background: Body Image Disturbance (BID) is the distorted experience of one’s body. BID presents a risk for the onset, maintenance and relapse of body dysmorphic disorder and eating disorders, including anorexia nervosa (AN). Current treatments tend to focus on the cognitive and behavioural aspects while overlooking the perceptual symptoms and BID frequently persists beyond physical...

Administration effects of four psilocybin mushroom extracts on serotonin levels and endothelial nitric oxide synthase activity levels in vivo and in vitro after one hour

Research Square (Research Square) July 18, 2023 Sanah Malomile Nkadimeng, L. Hay, Christiaan Ml Steinmann et al. 1 citation

Abstract Background Psilocybin-containing mushrooms induce antidepressant and momentary increase in blood pressure (BP) with potential risk to users with cardiovascular diseases. Irregularities in nitric oxide (NO) levels play a key role in endothelial dysfunctions leading to increases in BP. Mushrooms species show large variation in potency which may potentially induce different outcomes and...

Ethopharmacological evaluation of antidepressant-like effect of serotonergic psychedelics in C57BL/6J male mice

Research Square (Research Square) July 7, 2023 Rika Takaba, Daisuke Ibi, Keisuke Yoshida et al. 4 citations

Abstract Serotonergic psychedelics such as psilocybin, lysergic acid diethylamide, and DOI exert a hallucinatory effect through serotonin 5-HT 2A receptor (5-HT2A) activation. Recent studies have revealed that serotonergic psychedelics have therapeutic potential for neuropsychiatric disorders, including major depressive and anxiety-related disorders. However, the involvement of 5-HT2A in...

Abstract Background. Alongside a recent revival in the use of psychedelics in clinical settings, there have been increases in the prevalence of recreational use, with many using psychedelics to deal with difficult emotions or to improve wellbeing. While clinical research is conducted in carefully controlled settings, this is not necessarily the case for recreational use. In this mixed-methods...

Psilocybin Combines Rapid Synaptogenic And Anti-Inflammatory Effects In Vitro

Research Square (Research Square) March 8, 2022 Gabriella Smedfors, Elliot J. Glotfelty, Negar Kalani et al. 8 citations

Abstract Psilocybin is a psychedelic substance approaching clinical use. The drug has long-lasting effects after single or multiple administrations and enhances structural plasticity in the brain. Little is known if the plasticity inducing effects of psilocybin could be timed to other treatments and promote a larger effect. We investigated the effect of psilocybin on cultured mouse hippocampal...

This study sought to determine why such an exclusion exists, what the implications of the exclusion criteria are, and if there was agreement in expert opinion. Methods In-depth interviews with 12 experts in the...
