Neurostructural Correlates and Impulsive Mechanisms of Exercise Dependence in Middle-Aged and Elderly Adults: Evidence from Gray Matter and Structural Covariance Networks

Gratitude mediates the link of precuneus volume to depression in older women.

Abnormal Structural Covariance Networks and Impaired Executive Function in Adolescents with Mild Traumatic Brain Injury.

Findings might suggest that impaired executive function is associated with aberrant SCNs of hubs in ECN in adolescents with mTBI.

Distributed gray-white matter structural covariance alterations and interindividual heterogeneity in adolescents with functional/dissociative seizures.

OBJECTIVE To characterize distributed structural brain alterations and interindividual structural variability in adolescents with functional/dissociative seizures (FDS) and examine their relationship with dissociative symptom severity. METHODS Seventy adolescents with FDS and 70 healthy controls underwent high-resolu...

Neural and Cognitive Correlates of Adolescent Anxiety: Widespread Brain Network Alterations, Increased Control Costs, and Visuospatial Processing Deficits

This study investigated the neural substrates and cognitive correlates of adolescent anxiety, which are currently incompletely understood, in N=3499 youth (~51.0% females) from the Adolescent Brain Cognitive Study, with median(IQR) age =12.0(1.1) years. Resting-state fMRI, structural MRI, anxiety (scores and related...

Structural and functional alterations of posterior cingulate cortex subregions in successful cognitive aging

It is suggested that SCA was associated with lower PCC–prefrontal functional connectivity, but not with detectable preservation of PCC cortical thickness, which provides a potential framework for understanding heterogeneous cognitive-aging trajectories, but require confirmation in larger longitudinal cohorts.

Microstructural Brain Reserve Moderates the Associations Between 24‐h Movement Behaviors and Cognition in Older Adults: Cross‐Sectional Findings From the AGUEDA Trial

The associations between 24‐h movement behaviors and cognitive function may depend on microstructural brain integrity (i.e., GMMD), which highlights the importance of considering Alzheimer's disease‐related brain signatures when investigating lifestyle–cognition associations and support a more personalized approach to...
