This study examines the existence and mechanistic underpinnings of lasting neural, cognitive, and behavioural plasticity in response to N-N-dimethyltryptamine (DMT) in a hazardous drinking population. It combines behavioural, neuroimaging, ecological momentary and qualitative data to gain a holistic understanding of potential mechanisms of therapeutic change following DMT. Primarily, we test...

Abstract Psilocybin therapy (PT) is emerging as an effective intervention for Major Depressive Disorder (MDD), offering comparable efficacy to conventional treatments like selective serotonin reuptake inhibitors (SSRIs). Music, an emotionally evocative stimulus, provides a valuable tool to explore changes in hedonic and predictive processing mechanisms via expectancy violations, or ‘surprises’....

Abstract Major Depressive Disorder (MDD) is a highly prevalent mental health condition characterized by symptoms including anhedonia, which is defined as diminished pleasure, and impulsivity, which has been linked to increased substance abuse, self-harm and suicidal tendencies. Both anhedonia and impulsivity have been contributed to alterations in reward system function, with the striatum being...

Psychedelic therapies are an emerging class of treatments in psychiatry with great potential, however relatively little is known about their interactions with other commonly used psychiatric medications. As psychedelic therapies become more widespread and move closer to the clinic, they likely will need to be integrated into existing treatment models which may include one or more traditional...

There is growing evidence to support the use of the psychedelic drug psilocybin for difficult-to-treat depression. This paper compares the cost-effectiveness of psilocybin-assisted psychotherapy (PAP) with conventional medication, cognitive behavioural therapy (CBT), and the combination of conventional medication and CBT. A decision model simulated patient events (response, remission, and...

Psychedelic therapy (PT) is an emerging paradigm with great transdiagnostic potential for treating psychiatric disorders, including depression, addiction, post-traumatic stress disorder, and potentially others. 'Classic' serotonergic psychedelics, such as psilocybin and lysergic acid diethylamide (LSD), which have a key locus of action at the 5-HT2A receptor, form the main focus of this...
