The ethical and technical challenges of recent research with psychedelics and the attempt to regulate them as a health technology open a new horizon for reflections on scientific development and questions about how we experience spiritual and non-ordinary experiences of consciousness and relate to nature. We understand that Psychology needs to resort to psyc...
Background and HypothesisVisual hallucinations (VH) are a core symptom of both Lewy body diseases (LBDs; e.g., Parkinson’s disease and dementia with Lewy bodies) and serotonergic psychedelics (SPs; e.g., psilocybin and mescaline). While these classes of VH differ in etiology, shared pathways are suggested by overlapping phenomenology and neural mechanisms. T...
Inspired by the conference theme, Leaps and Stumbles, our panel takes a quantum leap beyond conventional notions of information. We provide a systematic consideration of information phenomena during altered states of consciousness generated by ingestion of “magic mushrooms.” Our exploration is anchored in the book, Psychedelic Information Theory: Shamanism i...
Psilocybin is a hallucinogen with complex neurobiological and behavioral effects. This is the first study to use MRI to follow functional changes in brain activity in response to different doses of psilocybin in fully awake, drug naive rats. Female and male rats were given IP injections of vehicle or psilocybin in doses of 0.03 mg/kg, 0.3 mg/kg, and 3.0 mg/k...
There is notable controversy about the role of psychotherapy in clinical trials of psychedelic-assisted therapy (PAT). This heated and perpetually evolving debate informs questions such as how much therapy should accompany a psychedelic intervention (Marseille et al., 2022), what type of therapy most effectively complements psychedelic administration (Cavarr...
After a long period of obscurantism, a possible role of psychedelics in clinical practice has progressively become a tangible perspective during the last two decades. However, the resounding enthusiasm linked to such 'psychedelic renaissance' runs the risk to unduly minimize the possible hazards associated with these compounds, while expanding their alleged ...
Background and aimsThis is the first systematic review of the extant literature on all major psychedelic-assisted treatment for alcohol use disorder (AUD), tobacco use disorder (TUD) and other substance use disorders (SUD). We aimed to summarise the evidence for efficacy of psychedelic-assisted treatment for AUD, TUD, and SUD; to evaluate its quality; and to...
Purpose of reviewExploration of the potential of serotonergic psychedelic drugs, such as psilocybin and LSD, as potential treatments for headache disorders. This review addresses the need for well-informed physician guidelines and discusses mechanisms, safety, and efficacy of these treatments. Further research, including the consideration of combination with...
Background and objectivePsilocybin is currently being extensively studied as a potential therapeutic agent for multiple psychiatric disorders. Here, a systematic literature review of all published pharmacokinetic data on the pharmacologically active metabolite of psilocybin, psilocin, is presented.MethodsThe review includes clinical studies that reported pha...
Psychedelics have emerged as a promising approach to treating mental disorders, challenging traditional paradigms in psychiatry. This study conducted an integrative literature review to investigate the advances, challenges, and implications of the therapeutic use of these substances, addressing the guiding question: “What are the current scientific perspecti...
In the rapidly growing field of psychedelic research, psilocybin (and active metabolite psilocin) has been proposed as a promising candidate in the search for novel treatments for neuropsychiatric disorders. Clinical trials have revealed that psilocybin has a large, rapid, and persistent effect in the improvement of symptoms of depression and anxiety. The sa...
This study presents a scientometric analysis of the scientific literature on the clinical use of psilocybin in mental disorders, covering publications from 2023 to 2025. The objective is to identify research trends, collaboration networks, and the scientific impact of this rapidly evolving field. A total of 359 unique records were retrieved from Scopus and W...
This scoping review examines the emerging evidence for psilocybin-assisted therapy (PAP) in treating trauma-related disorders such as posttraumatic stress disorder (PTSD), depression, and persistent post-concussion symptoms (PPCS), with specific implications for intimate partner violence (IPV)-related brain injury and PTSD. Guided by PRISMA-ScR methodology, ...
Psychedelic medicine has existed for thousands of years as a traditional, sacred practice and is now in varying stages of legalization for clinical application in the United States. PsychedelicAssisted Therapy uses specific psychoactive substances to facilitate altered states of consciousness in which clients have access to unconscious material and there is ...
There is increasing interest in establishing psychedelic research programs at academic medical centers. However, psychedelics are intensely psychoactive, carry considerable sociopolitical baggage, and most are Schedule I drugs, creating significant potential impediments to implementation. There is little formal guidance for investigators on navigating the co...
ObjectivesThis scoping review aimed to synthesize the existing data about psilocybin pharmacokinetics to learn what has been described regarding body disposition and safety when psilocybin was used in controlled research settings.MethodsWe performed a scoping literature review following the framework proposed by the JBI manual for evidence synthesis. Control...
IntroductionMushrooms, belonging to the phyla Ascomycota and Basidiomycota, comprise approximately 14,000 known species, among which a small fraction are toxic. While toxic mushrooms are primarily associated with adverse health effects, recent research highlights their potential as sources of bioactive compounds with promising therapeutic applications.Method...
Molecular brain imaging by positron emission tomography (PET) and single photon emission computer-tomography (SPECT) entails the mapping of the cerebral distribution of radiopharmaceuticals that track physiological processes such as blood perfusion and glucose metabolism, or the abundance in brain of specific molecular targets such as neuroreceptors. PET and...
OBJECTIVE: Unipolar and bipolar depression severely impact millions of individuals worldwide, with a significant subset of cases remaining unresponsive to conventional treatments. Psilocybin-assisted psychotherapy (PAP) has demonstrated therapeutic efficacy; however, the optimal psychotherapeutic approach remains undefined, ranging from unstructured models r...
Background: Psychedelic-assisted therapy (PAT) is experiencing a resurgence, with expanding evidence proving its efficacy for treatment-resistant psychiatric-mental health conditions. Psychiatric-mental health nurses (PMHNs) are uniquely positioned to provide PAT due to their integrated care capabilities, yet their roles are poorly defined. Aim: This review ...
