Mapping Higher-Order Topology in OCD Brain Networks with Hodge Laplacian

This paper introduces a Hodge-Laplacian framework to analyze higher-order topology in OCD brain networks, identifying loop-level abnormalities not detectable by conventional functional connectivity analysis.

Hippocampal and amygdala subfield volumes in obsessive-compulsive disorder differ according to medication status.

The paper examines hippocampal and amygdala subfield volumes in OCD patients and healthy controls, finding differences based on medication status.

White Matter Microstructure and its Relation to Clinical Features of Obsessive-Compulsive Disorder: Findings from the ENIGMA OCD Working Group

This study identifies white matter microstructural alterations in adult OCD patients and links them to clinical features, while finding no such abnormalities in pediatric patients.

Cognitive performance in children and adolescents at high-risk for obsessive-compulsive disorder

The paper investigates cognitive performance in children and adolescents at high-risk for OCD compared to healthy controls, finding impairments in processing speed and IQ discrepancy.

Subcortical brain volume, regional cortical thickness and cortical surface area across attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), and obsessive-compulsive disorder (OCD): findings from the ENIGMA-ADHD, -ASD, and -OCD working groups

This study compares structural brain differences across ADHD, ASD, and OCD using MRI data from multiple cohorts, finding disorder-specific alterations in brain volume and cortical thickness.
