Treatment-resistant depression (TRD) remains a formidable challenge in psychiatry, with nearly one-third of patients with major depressive disorder (MDD) failing to respond adequately to first-line pharmacological treatments. Pathophysiology in MDD has highlighted the N-methyl-D-aspartate (NMDA) glutamatergic system as a promising therapeutic target. In 2022, the US Food and Drug Administration...
Sleep paralysis is a temporary parasomnia with momentary atonia of the muscles in the body during the sleep-wake changes often accompanied by hallucinations and distress. Although it has an approximate prevalence of about 7.6 percent throughout the world, there is no particular pharmacotherapy that is approved. This paper compares 5 phytoconstituents of Hiptage benghalensis that include...
PsychedelicsMay 1, 2026Madeleine Cluck, Alison B. Purcell, Zuzana Kazan et al.
There is currently an ongoing resurgence in research on the therapeutic potential of psychedelics for psychiatric conditions. Psychedelic-assisted therapy (PAT) differs from most current forms of psychiatric treatment in two primary domains: its requirement for fewer doses (often just one), and its documented ability to promote profound insights, introspection, and cognitive shifts. Autism...
To synthesize evidence on pharmacological treatments for major depressive disorder (MDD) to inform updated Brazilian clinical guidelines. This overview included systematic reviews and meta-analyses published in the last 10 years, identified through MEDLINE, Cochrane Library, and SciELO. Eligible studies involved adults with MDD receiving pharmacological interventions. Risk of bias was assessed...

Depression is a prevalent comorbidity in cancer, yet conventional treatments show inconsistent efficacy. This review sought to provide a mechanism-based framework for managing cancer-related depression by exploring its unique pathophysiology and evaluating promising pharmacotherapies based on their alignment with these biological pathways. This narrative review synthesized evidence on promising...
The phase 2 data presented here support the development of TSND-201 for posttraumatic stress disorder (PTSD), a disorder for which there is a significant unmet need for rapid-acting and effective treatments. TSND-201 (methylone) is a highly selective, rapid-acting neuroplastogen that releases serotonin, norepinephrine, and dopamine without direct activity at 5-hydroxytryptamine (5-HT) 2A...
Depression is one of the most common mental health challenges people face today. It goes beyond just feeling sad — it shapes the way a person thinks, behaves, and experiences the world around them. The persistent low mood, the fading interest in things that once brought joy, the fog that makes even simple decisions feel overwhelming — all of it quietly chips away at a person's quality of life....
Psychedelic drugs are increasingly under investigation as potential therapeutic agents for mental health conditions and are being increasingly used recreationally. Psychedelic use may result in an episode of intense psychological distress, commonly referred to as a "bad trip." Bad trips represent a potentially volatile, erratic, and dangerous situation, which may, in extreme cases, require...
Psilocybe mushrooms (psilocybin/psilocin [PSI/PSC]) and ayahuasca (N,N-dimethyltryptamine [DMT]) are hallucinogenic serotonergic agonists. Pregnant and lactating women are frequently omitted from clinical studies; hence minimal developmental/reproductive/neurotoxicity (DART/DNT) and endocrine disruption (ED) data in humans are available. Hallucinogens contaminated with pesticides may have...
Background: 3,4-methylenedioxymethamphetamine (MDMA), or "Ecstasy," is a semi-synthetic stimulant and hallucinogen widely used recreationally. While known for producing euphoria, it is associated with severe medical complications including serotonin syndrome, rhabdomyolysis, and multi-organ failure. Although MDMA is known to cause various vascular and muscular lesions, deep venous thrombosis...
