Intravenous ketamine is a rapid-acting intervention for treatment-resistant depression (TRD) in adults with major depressive disorder and bipolar disorder (BD). While efficacy is established, a comprehensive integration of clinical, neurophysiological, biomarker, metabolic, and cognitive predictors remains lacking, limiting precision CNS-targeted therapy. To synthesize recent evidence on...
Psychedelic-assisted therapies (PATs) can produce rapid and sustained antidepressant effects, yet variability in response remains substantial. Identifying predictors and moderators is essential for optimising patient selection, preparation, and delivery. To map and synthesise the evidence on the predictors of antidepressant response to classic/serotonergic psychedelics administered with...
Treatment-resistant depression (TRD) affects about 30% of patients with major depressive disorder and remains a major clinical challenge.The limited effectiveness of classical antidepressants suggests that the pathophysiology of TRD is complex and extends beyond the traditional monoamine hypothesis.The aim of this paper was to present current concepts of the neurobiological background of TRD...
Abstract Mindfulness-based art therapy (MBAT) is an interdisciplinary intervention that integrates mindfulness techniques with art activities. While previous research has examined MBAT’s effectiveness in reducing depressive symptoms, little is known about the temporal dynamics of change during participation. This study explored session-to-session changes in mindfulness, rumination, and affect...
Consciousness is most frequently defined as a subjective experience of mental processes. The phenomenon of consciousness has always been a subject of great interest in various fields of science, including psychiatry, and the most prominent scientists have engaged in research on it. The studies performed in recent years have brought about novel data on the evolutionary and neurobiological...
Methamphetamine is a highly stimulating psychoactive drug that causes life-threatening addictions and affects millions of people around the world. Its effects on the brain are complex and include disturbances in the neurotransmitter systems and neurotoxicity. There are several known treatment methods, but their effectiveness is moderate. It must be emphasised that no drugs have been approved...
Abstract Objectives This study attempts to assess the concentration of two opposite-acting adipokines (anti-inflammatory adiponectin and pro-inflammatory resistin) in antidepressant-resistant patients undergoing ketamine infusion (KI) and electroconvulsive therapy (ECT). Methods The study group comprised 52 patients hospitalised due to episodes of depression in the course of bipolar disorders....
