BACKGROUND: Migraine and cluster headache are two primary headache disorders for which conventional treatments are limited. Classic psychedelic substances such as lysergic acid diethylamide (LSD) and psilocybin are potentially promising new treatment candidates for these conditions. AIMS: The aim of the present study was to investigate the possible relations...
Brain aging (BA) processes are complex, often affect multiple systems, and frequently lead to cognitive decline and increased susceptibility to insults. BA appears to be a primary risk for the development of many prominent neurodegenerative pathologies. The US Census Bureau predicts that the aging population (65+) will represent a greater proportion of the U...
Olfactory dysfunction (OD) has become increasingly prevalent since the COVID-19 pandemic, yet effective treatments remain limited. In recent years, anecdotal reports have emerged on the potential benefits of serotonergic psychedelics (lysergic acid diethylamide [LSD], psilocybin, etc.) in improving OD. To date, only one case series in the medical literature ...
The serotonergic psychedelics psilocybin, LSD and DMT hold great promise for the development of new treatments for psychiatric conditions such as major depressive disorder, addiction and end-of-life anxiety. Previous studies in both animals and humans have confirmed the effects of these drugs on neuronal activity and plasticity. However, the understanding of...
This study presents the development and validation of a high-performance liquid chromatography method with diode array detection (HPLC-DAD) for determining the content of tryptamines in methanolic extracts of dried fruiting bodies of mushrooms belonging to species of the Psilocybe genus. The objective is to initiate the assessment of tryptamine content in fu...
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: Psilocybin-containing mushrooms are gaining the attention of the scientific community due to the potential benefits offered by their psychoactive phytochemicals in the treatment of addiction and various mental health conditions. Although there are hundreds of different Psilocybe species, only a handful have been successfully cultivated under indo...
Abstract Background and Aims Networks of so-called underground, or illegal, psilocybin mushroom practitioners are popularly known to exist, though few systematic investigations of their practices have been conducted. We sought to uncover the experiences of a hidden community of psilocybin practitioners in order to inform scientific and policy dialogues about...
Treating amotivated states remains difficult. Classical psychedelic drugs (5-HT2A receptor agonists) such as LSD and psilocybin have shown therapeutic potential in treating such symptoms, but their development has been hindered by their undesirable hallucinogenic effects. There is increasing evidence that administration of psychedelics at dose levels too low...
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...
Integrating advanced pharmaceutical innovations and artificial intelligence (AI) offers transformative potential for psychiatric care. This Patent Highlight reviews novel therapeutic strategies, including the synergistic use of monoamine antidepressants and short-duration psychedelics, alongside AI-driven behavioral efficacy tracking. The combination of sele...
5HT 2A R is a G-protein-coupled receptor that drives many neuronal functions and is a target for psychedelic drugs. Understanding ligand interactions and conformational transitions is essential for developing effective pharmaceuticals, but mechanistic details of 5HT 2A R activation remain poorly understood. We utilized all-atom molecular dynamics simulations...
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...
Serotonin receptors, also known as 5-hydroxytryptamine (5-HT) receptors, are a diverse family of G protein-coupled and ligand-gated ion channel receptors that mediate the physiological effects of the neurotransmitter serotonin. These receptors are widely distributed throughout the central and peripheral nervous systems, where they regulate numerous processes...
Physical touch is often included as a supportive or therapeutic tool in psychedelic-assisted therapy (PAT), involving instrumental forms of physical contact, supportive touch and somatic techniques. However, participants under the influence of psychedelics have reduced capacity to provide consent, are more suggestible and may experience and interpret therape...
Selecting the optimal dose of psilocybin for treating Major Depressive Disorder (MDD) and Treatment-Resistant Depression (TRD) is crucial for clinical development and regulatory approval. This meta-analysis evaluates psilocybin's efficacy and safety in treating MDD to determine the optimal dose and timing for clinical trials. A systematic review and Dose-Res...
While the movement to liberalize psychedelics bears many parallels to that of cannabis, there are important differences that must be considered in development of regulatory policy. It is critical to avoid conflating debates about liberalization for therapeutic and recreational purposes. As with cannabis, this conflation has been driven by advocates of recrea...
Abstract Background Traditionally associated with recreational and spiritual uses, psychedelics have gained attention in psychotherapy for their therapeutic potential. Functioning as potent 5-hydroxytryptamine (5HT) agonists, these compounds have demonstrated the ability to enhance neural plasticity by activating serotoninergic and glutamatergic systems. Des...
Understanding neuromodulatory effects of serotonin 2A receptor (5-HT2A R) agonists with diverse pharmacological profiles is relevant to advancing psychedelic-related drug applications. We performed simultaneous positron emission tomography (PET) and pharmacological magnetic resonance imaging (phMRI) in anesthetized nonhuman primates (NHP; N = 3) to examine p...
Background: Psychedelics such as psilocybin, lysergic acid diethylamide, and 3,4-methylenedioxymethamphetamine are increasingly recognized for their potential therapeutic benefits in treating complex and chronic mental health conditions. Growing public interest in psychedelics may drive increased consumption outside of medically supervised clinical trials. C...
