Mindfulness-based cognitive therapy (MBCT) is a promising intervention for generalized anxiety disorder (GAD). Although GAD is associated with cognitive impairments, it remains unclear whether MBCT benefits cognitive functioning in clinical practice. This study examined outcomes of MBCT among adults with GAD in a routine clinical setting. In this assessor blinded randomized trial, 140 adults...
Anhedonia is a core feature of major depressive disorder (MDD) that is frequently resistant to available treatments. Psilocybin's specific efficacy for anhedonia remains unclear. To evaluate psilocybin's efficacy for anhedonia in treatment-resistant MDD. In this randomized, double-blind, placebo-controlled trial, 20 participants with treatment-resistant MDD received psilocybin (25 mg or 1 mg)...
Several studies have reported entropy reductions in regions of the brain associated with affective-regulatory and reward- and motivation-related processes in patients with major depressive disorder. However, whether low-dose ketamine modulates this reduction remains unclear. We analyzed resting-state functional magnetic resonance imaging data from two single-infusion low-dose ketamine trials....
Intranasal (es)ketamine has shown efficacy in therapy of treatment-resistant depression (TRD). However, its effects on suicidality have not been fully elucidated. We conducted a retrospective longitudinal cohort study of 80 patients affected by TRD, treated with intranasal (es)ketamine. Suicidality was assessed using item 10 of the clinician-rated Montgomery-Åsberg Depression Rating Scale...
Mindfulness-based interventions (MBIs) have been identified as a complementary treatment for children with ADHD. While there is a growing interest in developing MBIs in online formats, its application in parents is largely based on healthy populations. A two-arm randomized controlled trial (RCT) was designed to investigate the effectiveness of an online MBI (arm 1) compared with an online...
Treatment-resistant depression (TRD) affects 30-60% of individuals with major depressive disorder and carries substantial morbidity and healthcare costs. Intravenous (IV) ketamine (KET) is a rapid-acting antidepressant, but benefits are often transient, prompting augmentation to sustain efficacy or improve tolerability. We conducted a systematic review and meta-analysis of randomized controlled...
Chronic psychological stress is a major public health problem with adverse effects on mental health, health-related quality of life (HRQoL), and work functioning. Transcendental Meditation (TM) is a standardised meditation that may reduce stress and enhance wellbeing, yet long-term evidence in workplace settings is limited. This study evaluated the effect of TM on perceived stress and related...
Ketamine/esketamine produce rapid antidepressant effects, with growing interest in how acute subjective experiences and the surrounding set and setting shape clinical outcomes. Little is known about how audiovisual adjustments during ketamine/esketamine treatment influence comfort, tolerability, or patient experience, despite their common use in clinical practice. Virtual reality (VR) is one...
Suicidal ideation covaries with depressive severity during six-month real-world esketamine treatment in a cohort enriched for borderline personality disorder.
Anhedonia, a core symptom of major depressive disorder (MDD), is associated with illness severity, suicide risk, poor functioning, and predicts poor response to antidepressants. While no treatments are approved, ketamine and esketamine show promise in reducing anhedonia. This study examines clinical and sociodemographic features linked to anhedonia treatment response in treatment-resistant...
BACKGROUND: Ketamine is an effective rapid-acting treatment for treatment-resistant depression (TRD), producing antidepressant effects within hours of administration. Because it induces states of heightened neuroplasticity and psychological openness, psychotherapy may enhance its therapeutic effects. METHODS: This exploratory, nonrandomized, open-label clinical trial evaluated the adjunctive...
The contribution of patient support to psilocybin's antidepressant effects remains uncertain. Relationships between therapeutic alliance (Scale to Assess Therapeutic Relationship-Patient version; STAR-P), psychedelic experience (Five-Dimensional Altered States of Consciousness Questionnaire and Emotional Breakthrough Inventory; 5D-ASC and EBI) and clinical outcomes (Montgomery-Åsberg Depression...
This study evaluated the long-term comparative effectiveness and safety of esketamine versus injectable ketamine and esketamine versus oral antidepressants for major depressive disorder (MDD). This emulated target trial utilized observational data from a cohort of U.S. adults with MDD between 2018 and 2024. Patients were categorized into those receiving esketamine, injectable R,S-ketamine, and...
This systematic review and meta-analysis of six randomized controlled trials aimed to investigate the temporal changes in the efficacy and safety of psilocybin treatment for major depressive disorder (MDD). Separate meta-analyses were conducted for standard-dose psilocybin (25 mg/session, or 20-30 mg/70 kg/session) and low-dose psilocybin (10 mg/session or 15.05 mg/70 kg/session) subgroups....
Ketamine and esketamine have been increasingly used as adjunctive treatments for treatment-resistant depression (TRD), yet evidence on pharmacological interactions with commonly prescribed psychotropic medications remains limited. This study evaluated the association between concomitant lamotrigine, lithium, and benzodiazepine use and antidepressant outcomes during subcutaneous esketamine...
Treatment-resistant depression (TRD) is a heterogeneous condition in which symptoms such as anhedonia, rumination, and anxiety contribute to persistent disability. Esketamine nasal spray (ESK-NS), accelerated repetitive transcranial magnetic stimulation (arTMS), and adjunctive brexpiprazole represent novel therapeutic options with distinct mechanisms, though their domain-specific effects in...
Rapid clinical and EEG microstate changes 24 h after intranasal esketamine in major depressive disorder with suicidal ideation: a prospective paired study.
Ketamine and its enantiomer esketamine are efficacious in 30-35% of the patients with treatment-resistant depression (TRD). Increased serum brain-derived neurotrophic factor (BDNF) following treatment has been proposed as a potential biomarker of antidepressant response. This is based on studies evaluating single intravenous ketamine treatment. BDNF expression at different treatment schedules...
Major depressive disorder (MDD) is a leading cause of disability worldwide, with a significant portion of patients experiencing treatment-resistant depression (TRD). Ketamine, a rapid-acting antidepressant, has shown promise in alleviating symptoms of TRD and suicidality, but variability in treatment response remains a challenge. Identifying neuroimaging biomarkers that predict responsiveness...
Depression is a common mental health disorder affecting millions worldwide. Pharmacotherapies are partially effective, but numerous side effects often make them unfavorable. Recent investigations show that mindfulness meditation effectively mitigates depression-symptoms but the underlying mechanisms remain elusive. Here, we examined the sequential influence of emotion regulation (ER) and...
Major depressive disorder (MDD) ranks among the foremost contributors to disability worldwide, yet its neurophysiological mechanisms remain poorly understood. Excitation-inhibition (E/I) imbalance has been implicated in MDD pathophysiology, but cortex-wide E/I ratio and its molecular substrates in MDD remain unknown. Resting-state functional magnetic resonance imaging data from 254 MDD patients...
