Background/Objectives: Non-response to initial treatment options for major depressive disorder (MDD) is a common clinical challenge with profound deleterious impacts affected patients. Few treatments have received regulatory approval treatment-resistant depression (TRD). Methods: A systematic search of United States and European Union trials registries was conducted identify Phase II, III, or IV trials, last update posted on after 1 January 2020, that were evaluating medications TRD. For both the US EU registries, condition term "treatment resistant depression" associated lower-level terms (per registry protocol) used. registry, secondary using "depressive disorders" modifying "inadequate" also performed capture registrations not tagged as Two additional searches in "suicide" "anhedonia" transdiagnostic targets investigational medications. Trials categorized based primary mechanism action trial's medication. Results: Fifty TRD, 20 anhedonia, 25 suicide identified. Glutamate system modulation currently most compounds development, including antagonists allosteric modulators NMDA receptors, AMPA metabotropic type 2/3 glutamate intracellular effector molecules downstream signaling.

Importance Mounting evidence supports the role of spiritual, existential, religious, and theological components in mediating psychedelic-assisted therapy, yet integration these elements into clinical setting is lagging Observations Although therapy commonly produces spiritually, existentially, religiously, or theologically relevant experiences for patients, have not been systematically integrated psychotherapies that accompany therapeutic uses psychedelics. As a key feature potential mediator effects, evidence-based therapies should include topics treatment model. Research across multiple diagnostic targets contexts suggests spiritually are effective, feasible, produce add-on benefits outcomes, which particularly germane to Established standards psychotherapy may be fruitfully applied therapy. Objectives based on informed by considerations specific psychedelics recommended. Conclusions Relevance Spiritual, topics’ needed ensure culturally competent, aligned with highest care. Neglecting address can detract from cultural competence, contribute risks potentially undermine success.

During the past decade, there has been extraordinary public, media, and medical research interest in psychedelics as promising therapeutics for difficult-to-treat psychiatric disorders. Short-term controlled trial data suggest that certain are effective safe treatment of major depressive disorder, treatment-resistant depression, posttraumatic stress disorder. Preliminary evidence also supports efficacy other disorders (e.g., tobacco alcohol use disorders). Notwithstanding promise psychedelics, concerns have arisen with respect to interpretability translatability study results. For example, aspects related short- long-term safety, abuse liability, essentiality psychedelic "trip" psychological support are, inter alia, insufficiently characterized agents. The overarching aims this overview 1) review methodological affect inferences interpretation extant studies disorders, 2) provide guidance future development psychiatry, critical clinical implementation.

There is notable controversy about the role of psychotherapy in clinical trials psychedelic-assisted therapy (PAT).

The need to identify effective therapies for the treatment of psychiatric disorders is a particularly important issue in modern societies. In addition, difficulties finding new drugs have led pharmacologists review and re-evaluate some past molecules, including psychedelics. For several years there has been growing interest among psychotherapists psilocybin or lysergic acid diethylamide obsessive-compulsive disorder, depression, post-traumatic stress although results are not always clear definitive. fact, mechanisms action psychedelics yet fully understood molecular aspects be well defined.

Abstract Preparing participants for psychedelic experiences is crucial ensuring these are safe and, potentially beneficial. However, there currently no validated measure to assess the extent which well-prepared such experiences. Our study aimed address this gap by developing, validating, and testing Psychedelic Preparedness Scale (PPS). Using a novel iterative Delphi-focus group methodology (‘DelFo’), followed qualitative pre-test interviews, we incorporated perspectives of expert clinicians/researchers users generate items scale. Psychometric validation PPS was carried out in two large online samples (N = 516; N 716), scale also administered before after 5–7-day psilocybin retreat 46). Exploratory confirmatory factor analysis identified four factors from 20-item PPS: Knowledge-Expectations, Intention-Preparation, Psychophysical-Readiness, Support-Planning. The demonstrated excellent reliability (ω 0.954) evidence supporting convergent, divergent discriminant validity obtained. Significant differences between those scoring high low (on preparedness) experience were found on measures mental health/wellbeing outcomes assessed experience, suggesting that has predictive utility. By prospectively measuring modifiable pre-treatment preparatory behaviours attitudes using PPS, it may be possible determine whether participant generated appropriate ‘set’ therefore likely benefit or at least, less harmed.

Major Depressive Disorder (MDD) is one of the most disabling diseases in world. MDD traditionally diagnosed based on a patient’s symptoms, which can lead to misdiagnosis. Although pathogenic mechanisms are unknown, several studies have identified mitochondrial dysfunction as central factor onset and progression MDD. In context MDD, alterations metabolism imbalances energy production oxidative stress, contributing disorder´s underlying pathophysiological mechanisms. Consequently, identification key biomarker for early accurate diagnosis represents significant challenge. Faced with limits traditional treatments antidepressants, new pharmacological therapeutic targets being investigated such ketamine/esketamine, psychedelics, or anti-inflammatories. All these drugs show potential antidepressant effects due their speed action ability modulate neuroplasticity and/or motor processing. parallel, non-pharmacological studied, like Transcranial Magnetic Stimulation (TMS) Deep Brain (DBS), recognized neuronal activity offer treatment alternatives. As cellular directly related respiration, aim this review examining link between assessing how biomarkers could provide more objective precise diagnostic tool, exploring other addition specific focus emerging targets. Finally, detailed analysis strengths, weaknesses, opportunities, threats approaches was carried out, highlighting challenges that must be addressed.

Unlike classical antidepressants, psychedelics such as psilocybin have been shown to induce a rapid antidepressant response. In the wake of this development, interest has emerged in ultra-fast, short-acting 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) and N,N-dimethyltryptamine (DMT) with expectation that these can produce effects following an intense but brief psychedelic intervention. The current paper reviews clinical pharmacology 5-MeO-DMT DMT their potential benefits challenges treatment depression. Both compounds display affinities for variety monoamine receptors transporters, mostly so serotonergic (5HT) receptors, including 5HT
