Background: Traumatic brain injury (TBI) can result in prolonged post-concussive syndrome and chronic hypoxic-ischemic brain injury (HIBI) sequelae remains therapeutically challenging with the persistence of significant neurological and cognitive impairments. While conventional treatments often provide limited relief, emerging research explores alternative therapeutic interventions, including...
A ibogaína é um alcaloide indólico extraído da Tabernanthe iboga, investigado por seu possível papel na redução de sintomas de abstinência, fissura e recaída em transtornos por uso de substâncias. Este estudo teve como objetivo analisar, por meio de revisão de literatura, as evidências científicas sobre eficácia, segurança, mecanismos farmacológicos e implicações ético-regulatórias do uso da...
Classical serotonergic psychedelics, such as psilocybin, show emerging evidence of therapeutic potential across a range of mental health disorders, including depression, anxiety, and substance use disorders, with indications of transdiagnostic efficacy. While early-phase studies yielded encouraging results, recent larger-scale phase 3 trials, such as those evaluating psilocybin for...
Introduction MM120 (lysergide D-tartrate, LSD, CAS 32426-57-6) is under development as a potential treatment for generalized anxiety disorder and major depressive disorder. MM120 may elicit profound lasting psychological changes through interaction with brain 5-HT1A, 1B, 2A, 2C, 6 and 7 receptors, among others, while the complete mechanism is not clear. Objectives The study was performed to...

Introduction Intravenous (IV) ketamine has demonstrated rapid antidepressant and anti-suicidal effects in treatment-resistant depression (TRD), yet interindividual variability in response remains significant. One unexplored factor is the impact of concomitant antidepressant medication during ketamine treatment. Desvenlafaxine, a serotonin-norepinephrine reuptake inhibitor (SNRI), may enhance...
Abstract Catatonia is a potentially life-threatening psychomotor syndrome that can complicate substance intoxication and may be missed in acute psychiatric and addiction settings. Synthetic cannabinoids (e.g., Spice/K2) are associated with severe neuropsychiatric presentations including agitation, psychosis, autonomic instability, and diagnostic ambiguity. This talk presents a clinical case of...
Introduction Treatment-resistant depression (TRD) remains a major clinical challenge, with limited efficacy of available therapies. Psilocybin, a serotonergic psychedelic, has shown promising antidepressant effects. As recent studies have shown altered default mode network activity following psilocybin administration, further neuroimaging research in clinical populations is needed to clarify...
Introduction In treatment-resistant depression, commonly defined as a lack of response to two or more consecutive treatments of antidepressants. Esketamine (the S-enantiomer of ketamine) nasal spray, administered in combination with either a selective serotonin reuptake inhibitor (SSRI) or a serotonine-norepinephrine reuptake inhibitor (SNRI), is the only treatment approved in Europe...
Introduction Current antidepressants (SSRIs/SNRIs) face limitations including delayed onset (4–6 weeks) and modest efficacy (~50% response rates), while serotonergic psychedelics show rapid antidepressant potential via 5-HT2A agonism and synaptic plasticity but are hindered by hallucinogenic activity and 5-HT2B-mediated cardiotoxicity. Objectives To address these challenges, we characterize...
Introduction MM120 (lysergide D-tartrate, a formulation of LSD) is under development as a potential treatment for generalized anxiety and major depressive disorders. How psychedelic drugs interact at the TrkB receptor, a key target of neuroplasticity, is not reported. Objectives The study evaluated binding and functional activity of known serotonergic psychedelic compounds and SRI fluoxetine at...
