Abstract Lyme disease, caused by the bacterium Borrelia burgdorferi, is the most common vector-borne disease in the United States and Europe. Although antibiotics effectively treat most cases, an estimated 10-20% of patients develop post-treatment Lyme disease (PTLD), a chronic syndrome marked by fatigue, pain, cognitive difficulties, mood disturbance, and r...
The aim of this double-blind, placebo-controlled, within-subjects study is to determine whether other psychoactive substances can produce experiences akin to those seen with classic psychedelics. Screening involves a medical and psychiatric examination, including blood draw, history and physical, interviews, and questionnaires. Eligible participants will the...
Abstract IMPORTANCE Microdosing psilocybin may be a novel treatment for major depressive disorder (MDD). OBJECTIVE Assessing the antidepressant effects and safety of repeated low doses of psilocybin in participants diagnosed with MDD. DESIGN This was a Phase II, randomized, double-blind, placebo-controlled clinical trial. SETTING The trial was conducted from...
BACKGROUND: Major depressive disorder (MDD) is the leading cause of disability worldwide, affecting roughly 322 million people. Recently, doses of psilocybin have shown promise in treating mood disorders, sparking interest in other dosing practices. According to anecdotal reports and observational studies, microdosing psilocybin yields benefits to mental hea...
We carried out a systematic review of modern-era (1990-2025) placebo-controlled studies assessing the acute and post-acute effects of lysergic acid diethylamide, dimethyltryptamine and psilocybin on cognitive and psychological functions. From February 28 to March 19, 2025, PubMed and APA PsychINFO were systematically searched for placebo-controlled studies e...
MLS101 is being developed as a low dose psilocybin, that can be administered to treat neurological and psychiatric conditions. The purpose of this trial is to investigate brain activity, safety, tolerability, and PK of multiple doses of MLS101 in healthy participants. In recent years, high-dose psilocybin has gained attention for it potential therapeutic ben...
Anhedonia, a core symptom of depression, is often resistant to conventional treatments and significantly impacts quality of life. This secondary analysis aimed to evaluate the effects of psilocybin-assisted psychotherapy (PAP) on anhedonia severity in individuals with treatment-resistant depression (TRD). Participants (n = 30) with TRD and a primary diagnosi...
Background: Psilocybin treatment has shown promise across a range of psychiatric conditions. Mystical-type experiences during dosing sessions have been shown to predict the clinical effects of psilocybin treatment in depression, anxiety, and addiction. However, no studies have examined whether acute subjective experiences predict treatment response in obsess...
Psychedelic compounds, particularly psilocybin, have demonstrated remarkable therapeutic potential for mental health disorders through mechanisms involving structural neural plasticity. This comprehensive review examines recent breakthrough research revealing how psilocybin triggers activity-dependent rewiring of large-scale cortical networks. Using monosyna...
Recent advances in neuroscience have revealed unprecedented insights into how psilocybin, the psychoactive compound in magic mushrooms, induces therapeutic neural plasticity. This paper reviews groundbreaking research conducted by Cornell University and the Allen Institute for Brain Science, which employed genetically modified rabies virus for monosynaptic c...
Introduction: Cognitive flexibility is essential for behavioral adaptation in response to environmental changes and is impaired in various neuropsychiatric disorders. The serotonergic psychedelic psilocybin has shown potential in enhancing cognitive flexibility, although with mixed results. In this study, we investigated the effects of psilocybin on cognitiv...
As psychedelic-assisted psychotherapy gains momentum, clinical investigation of next-generation psychedelics may lead to novel compounds tailored for specific populations. 2,5-dimethoxy-4-bromophenethylamine (2C-B) is a psychedelic phenethylamine reported to produce less dysphoria and subjective impairment than the psychedelic tryptamine psilocybin. Despite ...
The development of novel, rapid-acting treatments and the resurgence of interest in the therapeutic potential of psychedelic-like compounds has stimulated excitement and enthusiasm within the pharmaceutical industry, and provided new hope for millions of individuals suffering with mental illness such as major depressive disorder and post-traumatic stress dis...
Psilocybin-assisted interventions have shown rapid reductions in depressive symptoms in controlled clinical settings, raising questions about biological mechanisms supporting durability beyond the acute drug effect. [5,7] Mechanistic accounts increasingly focus on neuroplasticity as a candidate pathway linking transient serotonergic receptor activation to lo...
Psilocybin is a psychoactive chemical compound that exerts its effects through the activation of serotonergic receptors. It occurs naturally in mushrooms of the genus Psilocybe. Despite its potential medical applications, this substance is regarded as a drug with no recognized medical use. Depression constitutes a psychiatric disorder of substantial global b...
This manuscript comprehensively reviews psilocybin-assisted therapy for major depressive disorder and treatment-resistant depression. It aims to synthesize current understanding regarding its mechanisms, efficacy, safety, costs, and accessibility, comparing it with conventional antidepressant and ketamine treatments. The methodology involved a narrative synt...
About 30-50% of patients with advanced illness experience depression, anxiety, or decreased sense of purpose and autonomy. Together, these are called psychological distress. Treatment options such as medication and therapy are available; however, they do not always work and can be time-consuming and expensive. We need treatments that work well, quickly, and ...
BACKGROUND: Recent advancements in psychedelic research have highlighted psilocybin's potential therapeutic benefits for various mental disorders. Understanding its effects on brain function and identifying predictors of individual responses are essential for developing effective treatments. METHODS: This double-blind, randomized, crossover, and placebo-cont...
This review examines the therapeutic efficacy of psilocybin for major depressive disorder by integrating findings from clinical trials, meta-analyses, and mechanistic research. A comprehensive literature search across major scientific databases identified empirical studies evaluating psilocybin’s effects on depressive symptomatology, safety, and underlying n...
