Aims: To examine whether psychedelic-like states of consciousness can be induced through brain stimulation techniques, evaluate their potential advantages over pharmacological psychedelics, and explore how stimulation-assisted psychotherapy may offer a clinically viable model for mental health treatment. Methods: A structured narrative review was conducted using PubMed and PsycINFO,examining...

Epilepsy is a chronic neurological disorder characterized by altered cortical excitability. The disorder is often associated with psychological distress and reduced quality of life. The purpose of the present review is to critically summarize the evidence on the effectiveness of meditation-based interventions for people with epilepsy. A comprehensive search was conducted in PubMed, Scopus, and...

While research on novel therapeutic applications of ketamine is expanding, particularly in controlled settings, there is limited exploration of its consumption related to self-treatment of psychiatric conditions. This study investigated the characteristics of people who use ketamine and psychedelics for self-treatment of psychiatric conditions, providing insight into patterns of use within this...

The success of ketamine, a dissociative anesthetic and non-competitive N-methyl-D-aspartate receptor (NMDAR) antagonist, as a rapidly acting antidepressant has ignited efforts to identify other novel depression treatments. In recent years, several clinical trials indicated that nitrous oxide (N2O), an inhalational dissociative anesthetic in clinical use for over 150 years, also has rapid and...

Ketamine has well-known dissociative, analgesic, and antidepressant properties, but it is unknown whether the neurophysiologic effects that are associated with these properties can be modulated separately from one another. Considering that specific cortical oscillations have been associated with specific therapeutic effects, modulating selective aspects of ketamine neurophysiology could inform...

Treatment-resistant depression (TRD), defined by unsuccessful response to multiple antidepressants, affects approximately one-third of individuals with major depressive disorder, yet its underlying molecular mechanisms remain poorly understood. Here, we developed a preclinical model of TRD in which mice exposed to chronic social defeat stress were sequentially treated with fluoxetine (FLX) and...

Ketamine consists of two enantiomers, (R)-ketamine and (S)-ketamine, which exhibit distinct pharmacological properties. Currently, only the (S)-enantiomer has been approved for the treatment of major depressive disorder, whereas recent clinical studies have failed to demonstrate an antidepressant effect for (R)-ketamine. The quantitative electroencephalography (qEEG) gamma-enhancing effect of...

Aims: To review and compare the safety, efficacy, cost-effectiveness and remission rates of electroconvulsive therapy (ECT) versus ketamine in patients with major depressive episodes. Methods: A narrative review of the literature was undertaken, focusing on randomised and non-randomised clinical trials, systematic reviews, and meta-analyses comparing ketamine and ECT in adults with major...

The medial prefrontal cortex (mPFC) undergoes extensive GABAergic interneuron maturation during adolescence, a process that establishes excitatory-inhibitory balance and supports adult cognitive function. Disruptions during this critical developmental period contribute to neuropsychiatric disorders, yet the enduring consequences for adult synaptic plasticity remain poorly understood. Here we...

Suicide is a major cause of death worldwide and a key public health challenge. Pharmacologic and neuromodulatory interventions are central to suicide prevention. This review summarizes evidence for these interventions with potential antisuicidal effects across major psychiatric disorders and, where possible, distinguishes their direct effects on suicide diathesis from those mediated by...
