Classic psychedelics such as lysergic acid diethylamide (LSD) and psilocybin induce mild cardiovascular activation in addition to their psychological effects. While these effects are well described in healthy adults, little is known about their dynamics in clinical populations undergoing psychedelic-assisted psychotherapy. This retrospective, observational, single-center study analyzed...
Lysergic acid diethylamide (LSD) has shown remarkable potential in modulating brain functional organization and dynamics. However, the exact mechanisms underlying its effects remain unclear. In this study, we employed a data-driven approach to analyze recurrent functional connectivity patterns in resting-state fMRI data and developed a parameterized feedback inhibition model to characterize...
Background: Depressive disorders affect approximately 280 million globally, with many finding treatments ineffective or limited by side effects. Growing evidence suggests that psychedelic therapies may help alleviate depressive symptoms. Among these, lysergic acid diethylamide (LSD) microdosing shows promise for major depressive disorder (MDD). However, research on LSD microdosing in clinical...
Expectations can impact antidepressant treatment and psychedelic therapy, often enhancing placebo effects and influencing outcomes. However, research in this context is lacking. Our study explored the expectations of participants with major depressive disorder (MDD) before microdosing lysergic acid diethylamide (LSD) in an open-label trial. Twenty-three individuals with MDD completed a...
Treatment with a single dose of a pharmaceutical formulation of lysergic acid diethylamide (LSD) resulted in a dose‐dependent reduction in anxiety in individuals with generalized anxiety disorder (GAD), a Phase 2b study has found. The two highest of four tested dose strengths of the MM120 formulation demonstrated significant improvement relative to placebo.
The analyses described in this SAP will assess the efficacy and safety of LSD (MB-22001) in comparison with active placebo (caffeine). The analysis described cover those for the primary, secondary and safety endpoints described in the Protocol.
Serotonergic psychedelics like psilocybin and LSD have shown potential therapeutic benefits for mental health conditions, including depression, PTSD, and addiction. However, research remains limited due to regulatory barriers and a lack of diversity in study populations. Spanish-speaking individuals, despite their significant global and U.S. presence, are underrepresented in psychedelic...
Microdosing psychedelics is an increasingly popular phenomenon where small amounts of psychedelic drugs are taken regularly. Qualitative data have been published regarding the experiences of microdosers, but never in the context of a randomised controlled trial. Semi-structured video interviews with 40 healthy males were conducted following a double-blind placebo-controlled trial of 10 µg of...
Major depressive disorder (MDD) affects approximately 5 % of the global population. Classic psychedelics have shown promise in treating various mental health disorders. This study evaluated the feasibility and tolerability of an 8-week regimen of microdosed lysergic acid diethylamide (LSD) as a treatment for major depressive disorder in an open-label phase 2A trial (LSDDEP1). Nineteen...
Psychedelic drugs have begun to show therapeutic promise. However, there is a growing research effort focused on creating nonhallucinogenic analogs of these substances. The goal is to develop new treatments for an expanding list of psychiatric and neurodegenerative disorders, while eliminating the complications and costs of treatment engendered by the subjective psychedelic experience....
