Reduction in Cerebral Perfusion after Heroin Administration: A Resting State Arterial Spin Labeling Study

PLoS ONE September 10, 2013 Niklaus Denier, Hana Gerber, Marc Vogel et al. 32 citations

In 15 heroin-dependent patients receiving stable heroin-assisted treatment, heroin reduced blood flow in the left anterior cingulate cortex, left medial prefrontal cortex, and insula compared to placebo. These brain areas are involved in self-regulation and emotional processing. The findings suggest that heroin's effects on these regions may contribute to its ability to reduce craving and produce relaxation in maintenance therapy.

Psychological Therapy Quantity and Depressive Symptom Reduction in Psychedelic-Assisted Therapy: A Systematic Review and Meta-Analysis.

JAMA network open January 2, 2026 Gianluca Andri Florineth, Isabell Klima, Anna Laura Boeker et al. 5 citations

In a systematic review and meta-analysis of 12 controlled clinical trials involving 733 adults with depressive symptoms, psychedelic-assisted therapy (PAT) with psilocybin or LSD produced a large overall reduction in depressive symptoms compared to control conditions. More hours of preparation therapy before the psychedelic session were significantly linked to greater symptom reduction. However, the number of post-dosing integration therapy hours, total therapy sessions, and longer follow-up periods were not associated with better outcomes. Most studies had high risk of bias due to ineffective blinding. The findings suggest that preparation therapy may be a key component in optimizing PAT outcomes, but further research is needed.

[Interventional psychiatric procedures and novel substances for the treatment of affective disorders: An overview and outlook].

Therapeutische Umschau. Revue therapeutique April 1, 2025 Tobias Bracht, Daniela Hubl, Kristina Adorjan et al. 1 citation

For patients with difficult-to-treat depression who do not respond to at least two antidepressant trials, remission rates are significantly lower than the 67% seen with initial or secondary pharmacological treatment. Brain stimulation procedures and novel substances offer innovative and effective options to complement standard therapies. This overview covers repetitive transcranial magnetic stimulation, electroconvulsive therapy, ketamine/esketamine, transcranial direct current stimulation, deep brain stimulation, and psychedelic-assisted psychotherapy, with an outlook on individualized, procedure-specific indications.
