Psychedelics and related compounds have shown efficacy for the treatment of a variety of conditions that are prevalent among older adults, including mood disorders, the psychological distress associated with a serious medical illness, post-traumatic stress disorder (PTSD), and prolonged grief disorder. Psychedelics also have properties that could help provid...
Psychiatric illnesses - such as major depressive disorder, anxiety disorder, substance use disorder, and posttraumatic stress disorder (PTSD) - are widely prevalent and represent a substantial health burden worldwide. Yet, conventional medications for mental illnesses often fail to provide relief to patients' disruptive and disabling symptoms. Existing and e...
IntroductionSmall-scale clinical studies with psychedelic drugs have shown promising results for the treatment of several mental disorders. Before psychedelics become registered medicines, it is important to know the full range of adverse events (AEs) for making balanced treatment decisions.ObjectiveTo systematically review the presence of AEs during and aft...
New medicines containing classic hallucinogenic and entactogenic psychedelic substance are under development for various psychiatric and neurological disorders. Many of these, including psilocybin, lysergic acid diethylamide (LSD), and 3,4-methylenedioxymethamphetamine (MDMA) are Schedule I controlled substances of the United States Controlled Substances Act...
ObjectiveSerotonergic psychedelics are re-emerging as potential novel treatments for several psychiatric disorders including major depressive disorder. The Canadian Network for Mood and Anxiety Treatments (CANMAT) convened a task force to review the evidence and provide a consensus recommendation for the clinical use of psychedelic treatments for major depre...
AbstractThe involvement of certain recreational drugs, namely, hallucinogens, in the development of hyperactive syndromes is well known, but not well studied. In this report, we expand on this relationship by documenting the development of substance-induced psychosis in a young patient who used a large amount of psilocybin and developed symptoms of a first p...
To investigate the efficacy of a 16 week treatment with PSIL428 patient reported anxiety levels in otherwise healthy individuals suffering from depression and or anxiety symptoms. Randomized, double-blind, placebo-controlled study assessing the efficacy of micro-dosed psilocybin on reducing anxiety and/or depression levels in adults Study summary: The Instit...
Psychedelics such as lysergic acid diethylamide (LSD), psilocybin (magic mushrooms), and mescaline exhibit intense effects on the human brain and behaviour. In recent years, there has been a surge in studies investigating these drugs because clinical studies have shown that these once banned drugs are well tolerated and efficacious in medically supervised lo...
Background: The use of psychedelic compounds to treat psychiatric disorders has become a very significant topic of research over the past several years. Psilocybin has risen to prominence as one of the most studied among these psychedelic compounds. Multiple trials have already shown that it can be a safe and efficacious treatment for various medical conditi...
Effects of serotonin 2A/1A receptor stimulation by psilocybin on mood and emotion processing in major depressive disorder: a randomized double-blind placebo-controlled study Major depressive disorder (MDD) is one of the world's greatest contributor to the global burden of disease and MDD affects around 17% of the Swiss population (Tomonaga et al. 2013). It i...
The word "psychedelic" (psyche (i.e., the mind or soul) and delos (i.e., to show)) has Greek origin and was first coined by psychiatrist Humphry Osmond in 1956, who had been conducting research on lysergic acid diethylamide (LSD) at the time. Psychedelic drugs such as N,N-DMT/DMT (N,N-dimethyltryptamine), 5-MeO-DMT (5-methoxy-N,N-dimethyltryptamine), LSD (ly...
Psychedelic drugs such as psilocybin have shown substantial promise for the treatment of several psychiatric conditions including mood and addictive disorders. They also have the remarkable property of producing persisting positive psychological changes in healthy volunteers for at least several months. In this study (NCT03289949), 35 medium-high doses of ps...
Rationale & objectives ± 3,4-Methylenedioxymethamphetamine (MDMA) and psilocybin are currently moving through the US Food and Drug Administration's phased drug development process for psychiatric treatment indications: posttraumatic stress disorder and depression, respectively. The current standard of care for these disorders involves treatment with psychiat...
Psychedelics extracted from plants have been used in religious, spiritual, and mystic practices for millennia. In 1957, Dr. Hofmann identified and synthesized the prodrug psilocybin, a substance present in more than 200 species of psychedelic mushrooms. Although there were limitations related to the scientific design of many studies, clinical observations pe...
Psilocybin-containing mushrooms have been consumed by various cultures in many different parts of the world for thousands of years. Psilocybin, a classic psychedelic, contains unique psychoactive properties and has been incorporated into religious ceremonies and investigated for its medicinal value. In the mid-20th century, psilocybin, along with most other ...
Recent clinical and preclinical evidence points towards empathogenic and prosocial effects elicited by psychedelic compounds, notably the serotonin 5-HT2A agonists lysergic acid diethylamide (LSD), psilocybin, N,N-Dimethyltryptamine (DMT), and their derivatives. These findings suggest a therapeutic potential of psychedelic compounds for some of the behaviour...
Psilocybin (a serotonin 2A, or 5-HT2A, receptor agonist) has shown preliminary efficacy as a treatment for mood and substance use disorders. The current report utilized positron emission tomography (PET) with the selective 5-HT2A receptor inverse agonist radioligand [11C]MDL100,907 (a.k.a. M100,907) and cortical regions of interest (ROIs) derived from restin...
Purpose of reviewDespite advances in treatment modalities for mood disorders over recent decades, further therapeutic options are still required. Increased research is occurring, with the pursuit of psychedelic-based pharmacotherapies for a range of mood disorders and other conditions.Recent findingsSerotonergic psychedelics have been found to modulate brain...
