Several studies suggested the efficacy of dispositional mindfulness and mindfulness-based interventions in reducing anxiety and depression in cardiovascular diseases. However, data on the impact of mindfulness on the psychological well-being of patients with an implantable cardioverter-defibrillator (ICD) are scarce. In this study, 422 patients with an ICD were prospectively recruited. Logistic...
Ketamine is an N-methyl-D-aspartate (NMDA)-receptor antagonist that produces sedation, analgesia, and dissociation at low doses and profound unconsciousness with antinociception at high doses. At high and low doses, ketamine can generate gamma oscillations (>25 Hz) in the electroencephalogram (EEG). The gamma oscillations are interrupted by slow-delta oscillations (0.1 to 4 Hz) at high doses....
AbstractOver the past decade, numerous open-label studies and early clinical trials have shown that psychedelics hold promise for the fast and possibly lasting relief of a wide range of conditions ranging from major depressive disorder, end-of-life anxiety, and obsessive-compulsive disorder to smoking, alcohol use, and eating disorders. Among the questions still to be resolved in this endeavor...
Psilocybin acutely alters several cognitive domains, with a localized rather than global focus, in a dose- and time-dependent manner. However, the significant methodological constraints call for further research, in the context of depression and with standardized protocols, with longitudinal studies also imperative.
Psychedelics (hallucinogenic 5-HT2A agonists such as psilocybin) are gaining recognition for their potential to treat a range of conditions, including anxiety-related psychopathology. Despite early promising results, the mechanisms by which psychedelic therapy alleviates anxiety are not well understood. Here, we review neural and cognitive mechanisms underlying anxiety-related psychopathology...
Prolonged Grief Disorder (PGD) is distinct from yet related to non-pathologic grief, depression, addiction, and Post-Traumatic Stress Disorder (PTSD) with a prevalence of up to 10% in bereaved populations. Hallmarks of PGD include functional impairment a year or more post-bereavement and intense yearning for the deceased. Current treatments for PGD are typically psychological rather than...
Taxonomic studies of dreams that continue to influence the dreamer's thoughts and feelings after awakening have distinguished three types of impactful dreams: nightmares, existential dreams, and transcendent dreams. Of these, existential dreams and transcendent dreams are characterized by recurrent metacognitive appraisal of the epistemic tension between complementary (a) metaphoric (A "is" B)...
Abstract Two views on psychedelic experiences include realism and idealism. While a realist view suggests that psychedelic experiences reveal a pre-given world to us, an idealist view suggests they are mere projections of a pre-given mind. This chapter highlights and contrasts their common tendency towards grasping and representations. It presents a promising alternative that aims at going...
Transmethylation in the context of psychiatry has historically referred to the enzymatic transfer of a methyl group from one biochemical to another, whose resulting function can change so dramatically that a biochemical like tryptamine, for example, is converted into the hallucinogen dimethyltryptamine. Central to endogenous methylation activity is the folate cycle, which generates the primary...
Zen Buddhism is perceived by many Buddhists as the path to transcendent truth, and Zen meditation is considered as an effective and representative approach. This article seeks to decipher the Zen meditation experience with the latest findings from Hawkins' theory of thousand-brain intelligence and the cerebral rewarding system. According to the findings, it suggests that Zen meditation might...
