Transdiagnostic Profiles of BOLD Signal Variability in Autism and Schizophrenia Spectrum Disorders: Associations with Cognition and Functioning

This study examines BOLD signal variability in autism and schizophrenia, finding reduced variability in these groups compared to controls, linked to poorer cognitive and functional outcomes.

Transdiagnostic Neurobiology of Social Cognition and Individual Variability as Measured by Fractional Amplitude of Low-Frequency Fluctuation in Schizophrenia and Autism Spectrum Disorders

The paper uses fALFF to compare brain activity patterns in ASD, SSD, and TDC groups, finding shared neurobiological features and variability differences.

Investigating cross-sectional and longitudinal relationships between brain structure and distinct dimensions of externalizing psychopathology in the ABCD Sample

The paper examines cross-sectional and longitudinal links between brain structure and externalizing psychopathology dimensions in children using ABCD data, finding region-specific associations with traits and symptom changes over time.

Disrupted maturation of white matter microstructure after concussion contributes to internalizing behavior problems in female children

This study finds that female children with concussions show greater post-injury internalizing and externalizing behavior problems, linked to disrupted white matter maturation.

Comparing the stability and reproducibility of brain-behaviour relationships found using Canonical Correlation Analysis and Partial Least Squares within the ABCD Sample

Cortico-amygdalar connectivity and externalizing/internalizing behavior in children with neurodevelopmental disorders

The paper examines associations between externalizing/internalizing behaviors and cortico-amygdalar connectivity in children with NDDs and TDC, finding no significant linear relationships.

Visuomotor Activation of Inhibition-Processing in Pediatric Obsessive Compulsive Disorder: A Magnetoencephalography Study

This study uses MEG to examine neural activity during a Go/No-Go task in medication-naive OCD youth and typically developing controls, finding altered motor and orbitofrontal cortex responses.

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.

Integration of Brain and Behavior Measures for Identification of Data-Driven Groups Cutting Across Children with ASD, ADHD, or OCD

The paper integrates brain imaging and behavioral data to identify transdiagnostic subgroups in children with ASD, ADHD, or OCD, finding stable groups based on cortical thickness and inattention symptoms.

Sex differences in Variability of Brain Structure Across the Lifespan

The paper examines sex differences in brain structure variability across the lifespan, finding greater regional variability in males and age-by-sex interactions in variability patterns.

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.

Personalized intrinsic network topography mapping and functional connectivity deficits in Autism Spectrum Disorder

This study introduces PINT, a method to identify individual-specific brain network variations in ASD and TD controls, finding greater variability in ASD and reduced hypo-connected regions after PINT application.
