Reconsidering evidence for psychedelic-induced psychosis: an overview of reviews, a systematic review, and meta-analysis of human studies.

Background: Persons with schizophrenia are excluded from psychedelic-assisted therapy due to concerns about the risk of triggering or worsening psychosis. However, there is limited meta-analytic data on the risk of psychedelic-induced psychosis in individuals with pre-existing psychotic disorders.

Methods: We conducted a systematic review, meta-analysis, and overview of reviews to assess the incidence of psychedelic-induced psychosis and symptom exacerbation in schizophrenia.

Insights from Ecstatic Epilepsy: From Uncertainty to Metacognitive Feelings.

Ecstatic epilepsy is a rare form of focal epilepsy linked to the anterior insula in which patients experience a blissful state with a unique set of symptoms, including a feeling of physical well-being, mental clarity, a sense of oneness with the universe, and time dilation. In this chapter, we reflect on how these symptoms coincide with our current knowledge of the insula's functions and explore how this stunning natural model can further inform our understanding of the insula's role in the sentient self, uncertainty and surprise monitoring, and metacognitive feelings.

Psychedelic-assisted therapy for palliative care within a home treatment setting: A case report.

Key Clinical Message: This case study describes the feasibility and safety of psychedelic-assisted therapy (PAT) as a home-based intervention for a patient with throat cancer experiencing significant existential distress. The patient tolerated the intervention well. This case supports the feasibility and safety of PAT for patients with life-threatening conditions in a home setting.

[Ethics in the practice of psychedelic-assisted psychotherapy].

This article proposes 10 points considered essential on the ethics associated with the practice of psychotherapy assisted by psychedelics (PAP) : 1) respect of the legal framework (LStup) of the use of psychotropic drugs ; 2) adequately manage psychedelics (storage, production and safety) ; 3) announce adverse effects to the competent authority ; 4) guarantee a psychotherapeutic follow-up ; 5) guarantee the safety of the patients during the treatment ; 6) establish indications on the basis of scientific evidence ; 7) do not confuse personal recreational use and strict medical use ; 8) avoid proselytizing or bad medical practices ; 9) do not to consider the personal consumption of psychedelics as a competency in care and 10) ensure that access to care is equitable and reasonable.

Psilocybin-assisted therapy for depression: A systematic review and dose-response meta-analysis of human studies.

Psilocybin is increasingly studied for its antidepressant effect, but its optimal dosage for depression remains unclear. We conducted a systematic review and a dose-response meta-analysis to find the optimal dosage of psilocybin to reduce depression scores. Following our protocol (CRD 42022220190) multiple electronic databases were searched from their inception until February 2023, to identify double-blind randomized placebo-controlled (RCTs) fixed-dose trials evaluating the use of psilocybin for adult patients with primary or secondary depression.

Can psychedelics enhance group psychotherapy? A discussion on the therapeutic factors.

Background: Despite the growth of psychedelic research, psychedelic-assisted group psychotherapy (PAGP) has received little attention in comparison to individual psychedelic-assisted psychotherapy models.

Methods: In this article, we aim to discuss the therapeutic potential of PAGP, as well as outline existing models and the challenges of this approach. Using Irvin Yalom's 11 therapeutic factors of group therapy as a basic framework, we analyse current literature from clinical studies and neurobiological research relative to the topic of PAGP.

Lessening of the pervasiveness of interpersonal patterns in borderline personality disorder explains symptom decrease after treatment: A process analysis.

Background: Problematic interpersonal patterns, as defined by the core conflictual relationship theme (CCRT) method, are part of the clinical presentation of clients with borderline personality disorder (BPD). So far, we do not know whether the pervasiveness of interpersonal patterns changes and if this change explains therapy outcome.

Methods: In a secondary analysis of a randomized controlled trial on a brief version of psychiatric treatment for BPD, a treatment with a psychodynamic focus, the present study included N = 39 clients.

[Microdosing LSD: practices and risks].

The practice of microdosing, which consists of ingesting a hallucinogen at 5-10% of a dose that would induce a psychedelic effect, has recently been the subject of growing interest by the media. The craze for microdosing has been relayed by the supposed effects of increased performance and creativity reported by professionals, especially in Silicon Valley. Despite this strong public interest, the evidence supporting this practice remains preliminary.

[What's new in addiction medicine].

The development of research, clinical practice and prevention in addiction medicine is, compared to other disciplines, more influenced by socio-political factors. Research on psychedelics has thus long been hampered by prohibitive policy but has recently been revived thanks to the relaxation of these political positions. The extensive prescription of baclofen for alcohol addiction is mainly the consequence of popular support and has so far not been clearly supported by specific research.
