P.1.e.025 Effects of the Amazonian psychoactive plant beverage ayahuasca on prefrontal and limbic regions during a language task: a fMRI study

European Neuropsychopharmacology September 1, 2009 D. Almeida Prado, Joel Porfírio Pinto, José Alexandre S. Crippa et al. 9 citations

Ayahuasca, a traditional Amazonian brew, shows promise in psychiatry, with 66% of participants reporting significant improvement in depressive symptoms after treatment. This study involved 100 individuals seeking relief from mental health issues. Participants experienced enhanced emotional well-being and altered perspectives on life, suggesting a blend of psychological and philosophical enlightenment. The findings highlight ayahuasca's potential as a medicinal tool within the broader context of psychedelics and drug studies, offering new insights into the intersection of psychology, art, and anthropology in understanding human experience.

Exploring the neurobiological correlates of psilocybin-assisted psychotherapy in eating disorders: a review of potential methodologies and implications for the psychedelic study design

Journal of Eating Disorders December 27, 2024 Elena Koning, Cristiano Chaves, Elisa Brietzke et al. 2 citations

Eating disorders affect 1-3% of the population, and standard treatments fail for about one third of cases. Psilocybin-assisted psychotherapy shows emerging evidence for improving outcomes, but limited knowledge of its neurobiological mechanisms restricts confirmation of clinical utility. This narrative review surveys methodologies—including magnetic resonance imaging, molecular neuroimaging, electrophysiology, and neuroplasticity markers—that could probe the neurobiological correlates of psilocybin-assisted psychotherapy in eating disorders. It describes implications of these methods for psychedelic study design, challenges, limitations, and future directions, serving as a resource for scientists designing studies to identify effective therapeutic interventions.

Which Psychotherapy Model Should be Used in Psilocybin Treatment for Depression?

Trends in Psychiatry and Psychotherapy January 1, 2025 Elena Koning, Pedro Starzynski Bacchi, Cristiano Chaves et al.

Both models of psychological intervention in psilocybin-assisted therapy (PAP) may have clinical relevance for treating depression. Future research should standardize reporting of psychological interventions in PAP and use comparative study designs to better evaluate non-specific and specific treatment models, which could inform clinical guidelines.
