This case study explores the potential role of mystical-type experiences in ketamine-assisted psychotherapy (KAP). A patient with generalized anxiety disorder and migraines underwent four intramuscular KAP sessions (0.5-0.9 mg/kg). Outcomes were assessed using the Outcome Questionnaire-45 (OQ-45), the Hood Mysticism Scale (HMS), and interviews. Greater therapeutic gains followed sessions with...
In this paper, which is in part intended as a speculative provocation and which combines philosophy of science, clinical practice and psychedelic therapy in a novel manner, we examine ketamine-assisted psychotherapy (KAP) through the lens of an expanded model of enactive cognition. While much work within both KAP and psychedelic-assisted therapy (PAT) in general has relied upon broadly...
Psychological and existential distress are common across the cancer trajectory and can impair quality of life, treatment adherence, and family functioning. Although psychosocial and pharmacological interventions provide meaningful support, their overall effects are often modest. This review examines the emerging role of psychedelic-assisted therapy (PAT) as a potential approach to better...
With growing research on the use of psychedelics to treat mental health conditions, greater attention to the psychosocial procedures accompanying substance administration is warranted. This scoping review aims to categorize psychosocial protocols used in research involving psychedelics as psychiatric treatment according to their purpose, denomination, format, therapeutic orientation,...
Background Methamphetamine use disorder (MAUD) is associated with substantial psychiatric and physical morbidity, and current treatment options remain limited. Ketamine-assisted psychotherapy (KAP) has shown promise in substance use disorders, but little is known about how individuals experience and interpret this intervention, particularly in MAUD. Qualitative investigation may provide insight...
Ketamine combined with psychotherapy has shown promise in treating posttraumatic stress disorder (PTSD), but predictors of clinical benefit remain unclear. In this systematic review and individual participant data meta-analysis (IPDMA), we examined patient- and treatment-level predictors of PTSD symptom change after combined treatment. Eligible studies combined ketamine with psychotherapy in...
Recent studies have shown promising results for psychedelics in the treatment of psychiatric disorders. Both in clinical and recreational settings, contextual elements, such as music, can influence the experience of users and may be linked to positive outcomes. This systematic review identifies how music is being selected and used in psychedelisc-assisted psychotherapy (PAP). The search adopted...
Abstract The Czech Republic, like many European countries, continues to face significant challenges in treating substance use disorders (SUDs), with high relapse rates and complex comorbidities often linked to trauma and mental illness. Psychedelic-assisted psychotherapy (PAP) has re-emerged internationally as a promising therapeutic modality, although available evidence remains heterogeneous...
Psychedelic therapies are moving from the margins of medicine into clinical practice, bringing unresolved ethical questions to the forefront. Among them, ketamine-assisted psychotherapy (KAP) has gained the widest medical acceptance, particularly for treatment-resistant depression (TRD). In August 2025, this development reached a new stage as Norway became the first country to approve...
