The genus Psilocybe of Basidiomycota includes more than two hundred species of mushroom-forming fungi, which are widely known for the production of the secondary metabolite psilocybin, a prodrug of its in vivo dephosphorylated active metabolite psilocin [1]. Psilocybin is being currently used in numerous clinical trials including the treatment of Major Depre...
End of life and palliative care has improved in recent decades but the psychopharmacological options available to clinicians and patients in these contexts remain limited. In particular, psychological factors such as depression, existential distress, and well-being remain challenging to address with current medications. Here, we review recent research on the...
Existential distress is a significant source of suffering for patients facing life-threatening illness. Psychedelic-Assisted Therapies (PAT) are novel treatments that have shown promise in treating existential distress, but openness to providing PAT may be limited by stigma surrounding psychedelics and the paucity of education regarding their medical use. Ho...
BackgroundTerminally ill patients may experience existential distress, depression, or anxiety, limiting quality of life in the final stage. Existing psychotherapeutic or pharmacological interventions have (time) limited efficacy. Psychedelic treatment may be a safe and effective alternative treatment option.AimSystematically review studies on psychedelic tre...
There is a growing body of research suggesting that palliative care patients coping with existential distress may benefit from psilocybin. However, there is a large gap regarding the perceptions of palliative care providers who may provide education, counseling services, recommendations, and/or prescriptions for psilocybin if it is decriminalized, commercial...
People with advanced cancer are at heightened risk of desire for hastened death (DHD), suicidal ideation (SI), and completed suicide. Loss of Meaning (LoM), a component of demoralization, can be elevated by a cancer diagnosis and predicts DHD and SI in this population. We completed a randomized controlled trial in which psilocybin-assisted psychotherapy (PAP...
The purpose of this study is to determine whether psilocybin-assisted group psychotherapy is a safe and feasible treatment for demoralization in long-term AIDS survivors (LTAS). This study is an open-label mixed-methods pilot study of an individual oral psilocybin drug session combined with ten sessions of an evidence-based, manualized brief group psychother...
The primary objective of this double-blind, placebo-controlled pilot study is to assess the efficacy of psilocybin administration (4-phosphoryloxy-N,N-dimethyltryptamine), a serotonergic psychoactive agent, on psychosocial distress, with the specific primary outcome variable being anxiety associated with cancer. Secondary outcome measures will look at the ef...
cancer patient: cancer patientWith the technological advances that have been made in diagnostics for cancer, more disease is being detected at an earlier stage. Although this generally improves the patient's chances for survival, a diagnosis of cancer can often provoke significant psychological distress in patients. A significant number of cancer patients wi...
BACKGROUND: A recently published randomized controlled trial compared single-dose psilocybin with single-dose niacin in conjunction with psychotherapy in participants with cancer-related psychiatric distress. Results suggested that psilocybin-assisted psychotherapy facilitated improvements in psychiatric and existential distress, quality of life, and spiritu...
Cancer is highly prevalent and one of the leading causes of global morbidity and mortality. Psychological and existential suffering is common in cancer patients, associated with poor psychiatric and medical outcomes. Promising early-phase clinical research (1960s to early 1970s) suggested a therapeutic signal for serotoninergic psychedelics (e.g. psilocybin,...
This chapter reviews what is known about the therapeutic uses of the serotonergic or classic hallucinogens, i.e., psychoactive drugs such as LSD and psilocybin that exert their effects primarily through agonist activity at serotonin 2A (5HT2A) receptors. Following a review of the history of human use and scientific study of these drugs, the data from clinica...
Anxiety and depression are some of the most common psychiatric symptoms of patients suffering with life-threatening diseases, often associated with a low quality of life and a poor overall prognosis. 5-HT2A-receptor agonists (serotonergic hallucinogens, 'psychedelics') like lysergic acid diethylamide (LSD) and psilocybin were first investigated as therapeuti...
BackgroundClinically significant anxiety and depression are common in patients with cancer, and are associated with poor psychiatric and medical outcomes. Historical and recent research suggests a role for psilocybin to treat cancer-related anxiety and depression.MethodsIn this double-blind, placebo-controlled, crossover trial, 29 patients with cancer-relate...
