Recent clinical trials have found that the serotonergic psychedelic psilocybin effectively alleviates anxiodepressive symptoms in patients with life-threatening illnesses when given in a supportive environment. These outcomes prompted Canada to establish legal pathways for therapeutic access to psilocybin, coupled with psychological support. Despite over one-hundred Canadians receiving...

Psilocybin has reemerged as a promising treatment for difficult-to-treat depression (DTD). Although there is limited evidence regarding interactions between psilocybin and other psychotropic drugs, clinical trials require that patients discontinue their antidepressants before study entry to isolate the benefits of psilocybin and to minimize the risk of adverse events. We present the first case...

Abstract Psychedelic substances, which can occasion mystical experiences, are sometimes used for religious and spiritual reasons. Despite strong links between psychedelics and spirituality, no previous systematic review has investigated connections between psychedelics and indicators of long-term spiritual growth. Thus, 34 empirical studies were analyzed with 19,724 total participants from 32...

Abstract Background Current drug policy classifies psilocybin, a substance produced by psychoactive mushrooms, as having a high potential for abuse, neglecting its therapeutic properties. We aimed to investigate if psilocybin mushrooms pose a risk to Brazilian public health compared to other toxic agents and whether evidence-based regulatory discussions are needed. Methods A retrospective...

In the past few years, psilocybin, a psychedelic compound found in "magic mushrooms" (psilocybin mushrooms), has undergone decriminalization in numerous cities across the US and has been legalized in Oregon and Colorado. Proponents of psilocybin decriminalization have emphasized its therapeutic potential in treating mental health disorders. Furthermore, psilocybin mushrooms are considered the...

Major depression disorder is an entity with high prevalence and worldwide impact. Current treatments present a non-response rate of 15-30%, and certain adverse effects are seen like apathy syndrome and lack of emotional response. It is stated that the treatment with psilocybin fungi allows the possibility of dose reduction and suspension of classic psychotropic drugs and entails changes on an...

Alzheimer’s disease (AD) stands as a formidable neurodegenerative ailment and a prominent contributor to dementia. The scarcity of available therapies for AD accentuates the exigency for innovative treatment modalities. Psilocybin, a psychoactive alkaloid intrinsic to hallucinogenic mushrooms, has garnered attention within the neuropsychiatric realm due to its established safety and efficacy in...

Abstract Serotonergic psychedelics (e.g., psilocybin) have shown potential for treating psychiatric disorders, with therapeutic effects lasting weeks after a single dose. Predictive processing theories posit that psychedelics work by loosening priors or high-level beliefs, including ingrained biases that have become pathological, leading to shifts in bottom-up vs top-down information processing...

Our study aimed to unravel the unknown mechanisms behind the exceptional efficacy of Psilocybin (PSI) in treating treatment-resistant depression (TRD). Focusing on Wistar-Kyoto (WKY) rats with a TRD phenotype and Wistar (WIS) rats as a normative comparison, we investigated behavioral and neuroplasticity-related responses to PSI, striving to shed light on the distinctive features of its...

Major depressive disorder (MDD) is a leading cause of disability worldwide across domains of health and cognition, affecting overall quality of life. Approximately one third of individuals with depression do not fully respond to treatments (e.g., conventional antidepressants, psychotherapy) and alternative strategies are needed. Recent early phase trials suggest psilocybin may be a safe and...

Psilocybin, a naturally occurring, tryptamine alkaloid prodrug, is currently being investigated for the treatment of a range of psychiatric disorders. Preclinical reports suggest that the biological effects of psilocybin-containing mushroom extract or "full spectrum" (psychedelic) mushroom extract (PME), may differ from those of chemically synthesized psilocybin (PSIL). We compared the effects...

Psilocybin is a widely studied psychedelic substance that leads to the psychedelic state, a specific altered state of consciousness. To date, the relationship between the psychedelic state's neurobiological and experiential patterns remains undercharacterized because they are often analyzed separately. We investigated the relationship between neurobiological and experiential patterns after...

The resurgence of interest in psychedelics as treatments for psychiatric disorders necessitates a better understanding of potential sex differences in response to these substances. Sex as a biological variable (SABV) has been historically neglected in medical research, posing limits to our understanding of treatment efficacy.
