AJP CME: December 2019 - Evidence for Dissociable Linkage of Dimensions of Psychopathology to Brain Structure in Youths

Activity Type:

  • Journal CME

Release Date: 12/1/2019

Expiration Date: 11/30/2021

  • AMA PRA Category 1: 1
  • Participation: 1



Objective: High comorbidity among psychiatric disorders suggests that they may share underlying neurobiological deficits. Abnormalities in cortical thickness and volume have been demonstrated in clinical samples of adults, but less is known when these structural differences emerge in youths. The purpose of this study was to examine the association between dimensions of psychopathology and brain structure.

Methods: The authors studied 1,394 youths who underwent brain imaging as part of the Philadelphia Neurodevelopmental Cohort. Dimensions of psychopathology were constructed using a bifactor model of symptoms. Cortical thickness and volume were quantified using high-resolution 3-T MRI. Structural covariance networks were derived using nonnegative matrix factorization and analyzed using generalized additive models with penalized splines to capture both linear and nonlinear age-related effects.
