Treatment-resistant depression (TRD) is a subset of Major Depressive Disorder which does not respond to traditional and first-line therapeutic options. There are several definitions and staging models of TRD and a consensus for each has not yet been established. However, in common for each model is the inadequate response to at least 2 trials of antidepressant pharmacotherapy. In this review, a...
Conform definiiei stabilite de Monitorul European pentru Droguri i Toxicomanie (European Monitoring Centre for Drugs and Drug Addiction -EMCDDA), o "substan psihoactiv nou este considerat orice substan narcotic sau psihotrop n form pur sau n preparate, care nu este controlat prin Conveniile privitoare la droguri ale Naiunilor Unite i care reprezint o ameninare la adresa sntii umane comparabil...
Neuroimaging studies of the psychedelic state offer a unique window onto the neural basis of conscious perception and selfhood. Despite well understood pharmacological mechanisms of action, the large-scale changes in neural dynamics induced by psychedelic compounds remain poorly understood. Using source-localised, steady-state MEG recordings, we describe changes in functional connectivity...
Abstract Background Psychedelic microdosing is the trending practice of using tiny repeated doses of psychedelic substances to facilitate a range of supposed benefits. With only a few published studies to date, the subject is still under-researched, and more knowledge is warranted. Social media and internet discussion forums have played a vital role in the growing visibility of the microdosing...
World-wide, researchers and practitioners in psychiatry are increasingly interested in the effectiveness of such substances as MDMA, LSA, and psylocibin in treating such disorders as addiction, post-traumatic stress disorder, and other types of depressive and anxiety. Although most of these substances were declared illegal in most countries during the 1970s, research into their use was...
Abstract Upon injury, psychotropic psilocybin‐producing mushrooms instantly develop an intense blue color, the chemical basis and mode of formation of which has remained elusive. We report two enzymes from Psilocybe cubensis that carry out a two‐step cascade to prepare psilocybin for oxidative oligomerization that leads to blue products. The phosphatase PsiP removes the 4‐ O ‐phosphate group to...
Depression and anxiety are prevalent psychiatric disorders that carry significant morbidity. Pharmacological and psychosocial interventions are used to manage these conditions, but their efficacy is limited. Recent interest into the use of psychedelic-assisted therapy using ayahuasca, psilocybin or lysergic acid diethylamide (LSD) may be a promising alternative for patients unresponsive to...
N-Benzylphenethylamines, commonly known as NBOMes, are synthetic psychedelic compounds derived from the phenethylamine class of psychedelics (2C-X compounds), which originally have been derived from the naturally occurring alkaloid mescaline. Analogously to their parent compounds and other classical psychedelics, such as psilocybin and lysergic acid diethylamide (LSD), NBOMes are believed to...
Psychedelics can induce eyes-closed imagery in which various visions can be experienced. These visions vary from simple geometrical patterns, to more complex imagery, to full immersion within “other realms”. Past studies suggest that the visual cortex is involved in processing these visions, yet these studies were limited into investigation of activity. In this thesis, the aim was to expand on...
Background: Health professional students frequently use alcohol and narcotics. The potential impact on academic performance and professional behaviour is concerning.Aim: This study aimed to determine self-reported use of alcohol, illicit substances (e.g. cannabis, lysergic acid diethylamide [LSD], magic mushroom, cocaine, crack, ecstasy, methamphetamine and heroin), prescription medication and...
