This neuroimaging study compared brain structural connectivity in 25 individuals with gambling disorder versus 28 healthy controls using diffusion tensor imaging and probabilistic tractography. The gambling disorder group showed increased striatal connectivity but reduced frontal lobe connectivity and fewer neural hubs, suggesting impaired network integration related to risk-taking control.
This randomized controlled trial compares two AI-delivered psychotherapy approaches—psychodynamic and cognitive behavioral therapy—for treating social anxiety disorder. The study evaluates the efficacy of automated therapy systems in delivering evidence-based interventions.
This study examines apathy as a frequently underrecognized feature of major depressive disorder in 154 outpatients, finding apathy present in 48% of the sample and associated with higher depression severity, lower cognitive function, and reduced quality of life. The research identifies specific depressive symptoms—inability to feel and loss of interest—as the strongest predictors of apathy, suggesting it represents a distinct clinical dimension warranting greater clinical attention.
This study analyzed data from 4,578 participants across seven datasets to identify core symptoms that differentiate apathy, depression, and anhedonia, which are clinically overlapping conditions. Using machine learning and validated assessment scales, researchers identified a robust five-factor structure revealing three distinct apathy domains (behavioral, social, emotional) separate from depression and anhedonia, with 10 core symptoms achieving >90% accuracy in differentiating pure syndromes.
This study examined whether ECT—a highly effective treatment for severe, treatment-resistant depression—changes mitochondrial metabolism by measuring serum metabolites in 102 patients across three time points using NMR spectroscopy. ECT induced both acute metabolic changes (increased citrate, glucose, glutamine, pyruvate; decreased formate, phenylalanine) and sustained shifts in energy metabolism (increased alanine/pyruvate, decreased ketone bodies), with ketone body reduction associated with clinical improvement.
