Towards mapping neuro-behavioral heterogeneity of psychedelic neurobiology in humans Flora Moujaes, Katrin H. Preller, Jie Lisa Ji, John D. Murray, Lucie Berkovitch, Franz X. Vollenweider, Alan Anticevic Biological Psychiatry, 2023 doi : 10.1016/j.biopsych.2022.10.021 ABSTRACT Precision psychiatry aims to identify markers of inter-individual variability that allow predicting the right treatment for each patient. However, bridging the gap between molecular-level manipulations and neural systems-level functional alterations remains an unsolved problem in psychiatry. After decades of low success rates in pharmaceutical R&D for psychiatric drugs, multiple studies now point to the potential of psychedelics as a promising fast-acting and long-lasting treatment for some psychiatric symptoms. Yet, given the highly [...]

Liechti Neuropsychopharmacology, 2022, 1-8. Doi : 10.1038/s41386-022-01297-2 Growing interest has been seen in using lysergic acid diethylamide (LSD) and psilocybin in psychiatric research and therapy. However, no modern studies have evaluated differences in subjective and autonomic effects of LSD and psilocybin or their similarities and dose equivalence. We used a double blind, randomized, placebo-controlled, [...]

Loss of Meaning (LoM), a component of demoralization, can be elevated by a cancer diagnosis and predicts DHD and SI in this population. We completed [...]

O’Keane Irish Journal of Psychological Medicine, 2020, 1-6. doi:10.1017/ipm.2020.94 The medium- to long-term consequences of COVID-19 are not yet known, though an increase in mental health problems are pre- dicted. Multidisciplinary strategies across socio-economic and psychological levels may be needed to mitigate the mental health burden of COVID-19. Preliminary evidence from the rapidly progressing field of psychedelic science shows that psilocybin therapy offers a promising transdiagnostic treatment strategy for a range of disorders with restricted and maladaptive habitual patterns of cognition [...]

Woolley Journal of Psychoactive Drugs, 2019, 51, (2) 174–188. doi : 10.1080/02791072.2019.1593559 Abstract Contemporary research with classic psychedelic drugs (e.g. lysergic acid diethylamide (LSD) and psilocybin) is indebted to the 20th century researchers and clinicians who generated valuable clinical knowledge of these substances through experimentation. Several recent reviews that highlight the contributions of this early literature have focused on psychedelic-assisted individual psychotherapy modalities. None have attempted to systematically identify and compile experimental studies of psychedelic-assisted group therapy. In therapeutic settings, psychedelics were often used [...]

Weissman ACS Pharmacology & Translational Science, 2021, 4, (2), 436-451 Doi : 10.1021/acsptsci.1c00024 Abstract Use of classic psychedelics (e.g., psilocybin, ayahuasca, lysergic acid diethylamide) is increasing and psychedelic therapy is receiving growing attention as a novel mental health intervention. Suicidality remains a potential safety concern associated with classic psychedelics and is, concurrently, a mental health concern that psychedelic therapy may show promise in targeting. Accordingly, further understanding of the relationship between classic psychedelics and suicidality is needed. Therefore, we conducted a systematic review [...]
