There are few effective treatments for eating disorders (EDs), and new interventions are urgently needed. The MEDication and other drugs For Eating Disorders ("MED-FED") survey investigated the lived experience of adults with EDs regarding their prescription and non-prescription drugs use. Psychedelic drugs were highly rated in this survey for their impact on ED symptoms and general mental...
Research into psychedelics has gained renewed interest due to their potential to address psychiatric, neurological, and other peripheral conditions. These substances offer long-term therapeutic benefits, contrasting with the side effects and limitations of current psychiatric medicines. This study examines the legislations and regulatory frameworks for psychedelics in Australia, Canada, The...
Innovative formulations of N,N-dimethyltryptamine (DMT) and 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) enable parenteral and intranasal delivery, respectively. These delivery systems overcome limitations of poor bioavailability and rapid metabolism, offering rapid-onset, short-duration therapeutic effects. The compositions support controlled psychedelic interventions for psychiatric...
Recent evidence suggests that psychedelics can induce rapid and long-lasting antidepressant effects. The generally acknowledged explanation for these traits is the phenomenon of neuroplasticity, although the exact underlying molecular mechanisms remain unclear. This study investigates the effects of psilocin, lysergic acid diethylamide (LSD) and N,N-dimethyltryptamine (DMT) on synaptogenesis...
Psychedelics offer promising outcomes in psychiatry. However, the preparation of participants (set) and the environmental conditions of taking a psychedelic (setting) are not standardized. We describe the set and setting for therapeutic use of psychedelic drugs in people with psychiatric disorders. In this systematic review, articles were identified in the PubMed and Web of Science databases...
Ischemic stroke is a leading cause of death and disability worldwide. Survivors face disability and psychiatric sequelae resulting from ischemia-induced cell death and associated neuroinflammation, and oxidative stress. Herbal medicines have been shown to elicit neuroprotective effects following stroke due to their anti-inflammatory and antioxidant effects. Preliminary evidence suggests that...

The "psychedelic renaissance" is sparking growing interest in clinical research, along with a rise in clinical trials. Substances such as 3,4-methylenedioxymethamphetamine (MDMA), psilocybin and N,N-dimethyltryptamine (DMT) are involved. The focus of this paper is on indolethylamine N-methyltransferase (INMT), a crucial enzyme in the biosynthesis of key compounds, including DMT, which meets...
Little is known about motives of healthy volunteers to participate in psychedelic trials and how they appraise their study experience retrospectively. This paper explored reasons why healthy people register for psychedelic trials, factors that they considered to contribute to either positive or negative study experiences, and under which circumstances they would seek a psychedelic experience...
Susac syndrome is a rare autoimmune endotheliopathy that affects the central nervous system, retina, and inner ear, characterized by encephalopathy, branch retinal artery occlusions, and sensorineural hearing loss. Due to the heterogeneity of its presentation, early diagnosis, and treatment remain challenging. To evaluate the clinical outcomes and radiological responses in two patients with...
It is unclear whether hallucinogenic tryptamine derivatives namely N,N-dimethyl-tryptamine (DMT) and 5-methoxy-N,N-dimethyl-tryptamine (5-MeO-DMT) exert positive inotropic effects in the human heart. Therefore, we measured the inotropic effects of these drugs in isolated left and right atrial preparations of mice that overexpress human 5-HT4 receptors (5-HT4-TG) and preparations from wild type...
