Theorizing that Psychedelic Assisted Therapy May Play a Role in the Treatment of Trauma-Induced Personality Disorders.

Journal of addiction psychiatry 2024 Gianni Martire, Daniel Sipple, David Baron et al. 341 citations

Borderline personality disorder (BPD) and post-traumatic stress disorder (PTSD) share overlapping neurobiological mechanisms particularly reward deficiency and stress-like anti-reward processes. And so, BPD may be reclassified as a "traumatic personality stress disorder" (TPSD) with ensuing common therapeutic strategies that may stabilize dopaminergic reward function such as...

Acute effects of MDMA on trust, cooperative behaviour and empathy: A double-blind, placebo-controlled experiment.

J Psychopharmacol June 15, 2020 Anna Borissova, Bart Ferguson, Matthew B. Wall et al. 37 citations

BACKGROUND: 3,4-Methylenedioxymethamphetamine (MDMA) is being actively researched as an adjunct to psychotherapy. It may be beneficial to trust, empathy and cooperative behaviour due to its acute prosocial effects. AIM: To test (a) the acute effects of MDMA on measures of empathy, trust and cooperative behaviour, and (b) subacute changes in mood three days after MDMA administration. METHODS: =7...

Neural correlates of the LSD experience revealed by multimodal neuroimaging

UNC Libraries April 22, 2020 Peter J. Hellyer, Luke T. J. Williams, Ben Sessa et al. 1 citation

Lysergic acid diethylamide (LSD), the prototypical “psychedelic,” may be unique among psychoactive substances. In the decades that followed its discovery, the magnitude of its effect on science, the arts, and society was unprecedented. LSD produces profound, sometimes life-changing experiences in microgram doses, making it a particularly powerful scientific tool. Here we sought to examine its...

Psilocybin for treatment-resistant depression: fMRI-measured brain mechanisms.

Sci Rep October 13, 2017 Robin Carhart-Harris, Leor Roseman, Mark Bolstridge et al. 590 citations

Psilocybin with psychological support is showing promise as a treatment model in psychiatry but its therapeutic mechanisms are poorly understood. Here, cerebral blood flow (CBF) and blood oxygen-level dependent (BOLD) resting-state functional connectivity (RSFC) were measured with functional magnetic resonance imaging (fMRI) before and after treatment with psilocybin (serotonin agonist) for...

Increased Global Functional Connectivity Correlates with LSD-Induced Ego Dissolution.

Curr Biol April 13, 2016 Enzo Tagliazucchi, Leor Roseman, Mendel Kaelen et al. 531 citations

Lysergic acid diethylamide (LSD) is a non-selective serotonin-receptor agonist that was first synthesized in 1938 and identified as (potently) psychoactive in 1943. Psychedelics have been used by indigenous cultures for millennia [1]; however, because of LSD's unique potency and the timing of its discovery (coinciding with a period of major discovery in psychopharmacology), it is generally...

Neural correlates of the LSD experience revealed by multimodal neuroimaging.

Proc Natl Acad Sci U S A April 11, 2016 Robin Carhart-Harris, Suresh Muthukumaraswamy, Leor Roseman et al. 887 citations

Lysergic acid diethylamide (LSD) is the prototypical psychedelic drug, but its effects on the human brain have never been studied before with modern neuroimaging. Here, three complementary neuroimaging techniques: arterial spin labeling (ASL), blood oxygen level-dependent (BOLD) measures, and magnetoencephalography (MEG), implemented during resting state conditions, revealed marked changes in...

The Effects of Acutely Administered 3,4-Methylenedioxymethamphetamine on Spontaneous Brain Function in Healthy Volunteers Measured with Arterial Spin Labeling and Blood Oxygen Level–Dependent Resting State Functional Connectivity

Biological Psychiatry January 10, 2014 Robin Carhart-Harris, Kevin Murphy, Robert Leech et al. 182 citations

The MTLs appear to be specifically implicated in the mechanism of action of MDMA, but further work is required to elucidate how the drug's characteristic subjective effects arise from its modulation of spontaneous brain activity.

Neural correlates of the psychedelic state as determined by fMRI studies with psilocybin

Proceedings of the National Academy of Sciences January 23, 2012 Alessandro Colasanti, Robin J. Tyacke, Robert Leech et al. 1,191 citations

Psychedelic drugs have a long history of use in healing ceremonies, but despite renewed interest in their therapeutic potential, we continue to know very little about how they work in the brain. Here we used psilocybin, a classic psychedelic found in magic mushrooms, and a task-free functional MRI (fMRI) protocol designed to capture the transition from normal waking consciousness to the...
