Post-traumatic stress disorder (PTSD) is a debilitating psychiatric condition that develops following exposure to a traumatic event. Individuals with this condition experience numerous physiological and behavioral alterations, including intrusive memories, avoidance of trauma-related stimuli, heightened anxiety, hypervigilance, impaired cognition, elevated resting heart rate and blood pressure,...

How is it that psychedelics so profoundly impact brain and mind? According to the model of "Relaxed Beliefs Under Psychedelics" (REBUS), 5-HT2a agonism is thought to help relax prior expectations, thus making room for new perspectives and patterns. Here, we introduce an alternative (but largely compatible) perspective, proposing that REBUS effects may primarily correspond to a particular (but...

ALSUntangled reviews alternate and off-label treatments prompted by patient interest. Here, we review psilocybin, a chemical derived from mushrooms and belonging in the category of drugs known as psychedelics. Psilocybin has plausible mechanisms for slowing ALS progression because of its ability to cross the blood brain barrier and effect neurogenesis and inflammation. Currently, there are no...

The rising prevalence of depression, with its associated suicide risk, demands effective fast-acting treatments. Ketamine has emerged as promising, demonstrating rapid antidepressant effects. While early studies show swift mood improvements, its precise mechanisms remain unclear. This article aims to compile and synthesize the literature on ketamine's molecular actions. Ketamine primarily works...

Psychedelic compounds continue gaining scientific and regulatory traction as potential new treatments for psychiatric disorders. While most psychiatrists will likely not work directly with these compounds, psychedelic research practices provide insights that may improve conventional psychiatric care. Through its emphasis on 'set and setting' (mindset and environment, respectively), psychedelic...

The revival of psilocybin in psychopharmacological research heralds a potential paradigm shift for treating mood and anxiety disorders, and other psychiatric conditions beyond the psychotic spectrum. This critical review evaluates current evidence on psilocybin's efficacy, juxtaposing potential benefits with the practical aspects of psychedelic-assisted psychotherapy (PAP) and the...

Abstract Background Peripheral levels of brain-derived neurotrophic factor (BDNF) are often used as a biomarker for the rapid plasticity-promoting effects of ketamine, psychedelics, and other psychoplastogens in humans. However, studies analyzing peripheral BDNF after psychoplastogen exposure show mixed results. In this meta-analysis, we aimed to test whether the rapid upregulation of...

Abstract Psychedelic drugs are under active consideration for clinical use and have generated significant interest for their potential as anti‐nociceptive treatments for chronic pain, and for addressing conditions like depression, frequently co‐morbid with pain. This review primarily explores the utility of preclinical animal models in investigating the potential of psilocybin as an...

In this article we aimed synthesize all available evidence regarding the effects of non-invasive brain stimulation (NIBS) techniques combined with mindfulness-based interventions (MBIs) on mental health indicators. We performed a systematic review of randomized controlled trials evaluating NIBS/MBIs combinations in clinical populations and a random effects pairwise meta-analysis of studies...
