ObjectiveEating disorders (EDs) are characterized by high rates of psychiatric comorbidity and suboptimal treatment outcomes. There remain critical gaps in research, including the exploration of effective transdiagnostic interventions. This forum article examines the potential of psilocybin treatment (PT) as a transdiagnostic intervention for EDs and common ...
Traumatic brain injury (TBI) causes persistent neurobehavioral deficits and increases the risk of psychiatric disorders, including depression, anxiety, and cognitive dysfunction linked to disrupted neuroplasticity, neuroinflammation, and serotonergic (5-HT) signaling. No effective pharmacotherapies exist for chronic TBI. Psilocybin, a psychedelic 5-HT2A rece...
Serotonergic psychedelics are increasingly investigated as treatments for affective disorders. Concerns persist regarding their potential to induce hypomania or mania, particularly in individuals with bipolar spectrum vulnerability. Whether these substances precipitate transient mood switches or contribute to persistent bipolar illness or diagnostic transiti...
Serotonergic psychedelics such as N,N-dimethyltryptamine (DMT) and 4-phosphoryloxy-N,N-dimethyltryptamine (psilocybin) show therapeutic promise for psychiatric and neurodegenerative disorders but may be limited by liabilities from serotonin (5-HT)-2A mediated psychoactive effects and potential cardiotoxicity via 5-HT2B activation. To address these limitation...
The goal of this randomized placebo controlled trial is to compare the antidepressant effect of a single oral dose of psilocybin 25 mg compared to 1 mg in 100 patients with cancer related major depressive disorder. The main question it aims to answer is: The primary objective of this study is to evaluate the efficacy of a single 25 mg oral dose of psilocybin...
Psilocybin can produce sustained benefits in affective and trauma-related disorders, yet if and how it reshapes sensory representations of learned valence associations remains largely unclear. To address this, we used longitudinal two-photon calcium imaging in awake C57BL/6 mice to examine how psilocybin modulates layer 2/3 auditory cortex activity at single...
In our original case report we provide detailed accounts of two research participants who reported the emergence of spontaneously recovered, previously forgotten traumatic memories of sexual assaults during psilocybin treatment. In their commentary of this article, Kangaslampi et al. argue that we preemptively label the experiences as dissociated traumatic m...
Anhedonia, a core symptom of depression, is often resistant to conventional treatments and significantly impacts quality of life. This secondary analysis aimed to evaluate the effects of psilocybin-assisted psychotherapy (PAP) on anhedonia severity in individuals with treatment-resistant depression (TRD). Participants (n = 30) with TRD and a primary diagnosi...
Psilocybin has been reported to decrease depression symptoms among individuals with bipolar disorder (BD), but has also been associated with reports of mania, psychosis and increased depression. With increasing recreational use of psilocybin, and the potential for psilocybin to be used as a treatment for depression, a better understanding of the risks and be...
Binge Eating Disorder (BED) is the most prevalent eating disorder and is associated with psychiatric comorbidities, health impairments, and decreased quality of life. Emerging evidence suggests that psilocybin-assisted therapy may promote cognitive and emotional flexibility and disrupt maladaptive behavioral patterns, making it a promising candidate for BED ...
There is a large and rapidly growing body of literature investigating the therapeutic effects of classic psychedelics in affective and anxiety disorders, but very few studies have examined the inverse of this, that is, the potential for psychedelics to inflict anxiety and affective symptoms. A systematic literature search was performed and 39 papers were inc...
Personality disorders (PDs) are characterized by rigid and maladaptive patterns of self- and interpersonal functioning, leading to high clinical burden and limited treatment outcomes. Schema Therapy (ST), an integrative psychotherapy rooted in cognitive-behavioral principles, conceptualizes PDs in terms of Early Maladaptive Schemas (EMS)-pervasive cognitive-...
In their recent case report article, Peck and colleagues suggested that two patients recovered dissociated traumatic memories during psilocybin treatment for anorexia nervosa. These case reports are of clinical and scientific interest and confirm that psychedelics may induce vivid memory-like experiences. However, the reports warrant scrutiny. Here, based on...
Background: Post-traumatic stress disorder (PTSD) is a debilitating condition leading to significant personal and societal burden. Standard treatments frequently demonstrate limited efficacy, leading to persistent symptoms and high dropout rates. Psilocybin has shown promise in treating depression, a condition that is often comorbid with PTSD. We aimed to ex...
