Multimodal Evidence for Large-scale Network Imbalance in Etomidate Use Disorder
Background: Etomidate use disorder (EUD) is an escalating public health issue in East and Southeast Asia, yet its neuroimaging features remain poorly understood. This study used simultaneous electroencephalography (EEG) and functional ne...

Open DOI
Disruption of ultrasonic vocalizations with systemic administration of the non-competitive N-methyl-D-aspartate receptor antagonist MK-801 in adult male mice
Objective: Social behavior and communication, including ultrasonic vocalizations (USVs), are important for survival and reproductive success across species. N-methyl-D-aspartate (NMDA) receptors contribute to the neural mechanisms underl...

Open DOI
33. Disruption of the retinoid X receptor–PPAR-γ axis is associated with appetite hormone dysregulation and cognitive dysfunction: a cross-sectional study of adolescents with first-episode bipolar disorder
Background: The role of the retinoid X receptor (RXR) and peroxisome proliferator–activated receptor-γ (PPAR-γ) axis in the pathophysiology of bipolar disorder (BD) remains poorly understood. The relationship of RXR–PPAR-γ axis disruptio...

646. Suicidal behaviour in a Kenyan forensic unit
Background: Suicide and suicidal behaviour are higher among psychiatric inpatients than in the general population. Patients in forensic units have the duality of mental illness and incarceration. Few studies have looked into the prevalen...

492. Comparative one-year follow-up of suicide attempters with and without borderline personality disorder
Background: Suicide attempts are a major public health challenge and are associated with a high risk of recurrence, especially during the months following the initial episode. This risk is strongly influenced by underlying psychiatric co...

Open DOI
784. A Retrospective Report of Efficacy and Tolerability of Low Daily Dose Ketamine for Depression and Anxiety in a Large Population Sample
Background: Use of intravenous ketamine or intranasal esketamine for depression is frequently limited due to resource requirements and cost. Alternative treatment models have used oral, sublingual or intranasal racemic ketamine, but opti...

534. Striatal dopamine synthesis trajectory in first-episode psychosis during amisulpride monotherapy and after switch to aripiprazole: a one-year [ 18 F]DOPA PET study
Background: Schizophrenia and related psychotic disorders are associated with elevated striatal dopamine synthesis from the first episode. While antipsychotics primarily improve symptoms through dopamine D₂ receptor blockade, it remains ...

523. Estimating clinically important differences in the adult attention deficit hyperactivity disorder self-report scale
Background: The adult attention deficit hyperactivity disorder (ADHD) self-report scale (ASRS), as one of the widely used patient-reported outcome measures (PROMs), played an important role in evaluating ADHD symptom severity and treatme...

376. Blood-brain barrier permeability as a determinant of depression risk in long-term beta-blocker users: a real-world TriNetX cohort study
Background: Beta-blockers (BBs) remain a cornerstone in the management of hypertension and cardiovascular disease. While early literature suggested a "depressogenic" effect, recent meta-analyses have largely refuted a general association...

110. Glutamatergic changes in the medial prefrontal cortex associated with psychosis history in bipolar disorder and their relationship to executive function
Background: Psychosis affects over half of individuals with bipolar disorder (BD) and has been linked to glutamatergic dysfunction within the default mode network (DMN). Altered glutamate/GABA signaling in the DMN may contribute to cogni...
