The Bidirectional Relationship Between Brain Features and the Dysregulation Profile: A Longitudinal, Multimodal Approach

The field of psychiatry increasingly highlights the importance of studying not only the influence of the brain on behavior, but also the long-term influences that the persistence of specific behaviors can have on the brain. A severe behavioral phenotype that puts children at risk for later psychopathology is the Child Behavior Checklist-Dysregulation Profile (CBCL-DP).1 In earlier work, Shaw et al.2 proposed a model in which the amygdala, nucleus accumbens, and orbitofrontal cortex, structures involved in the bottom-up response to emotional stimuli, are related to emotion dysregulation. Additionally, 3 key limbic white matter tracts have also been shown to be associated with CBCL-DP symptoms: the uncinate fasciculus, cingulum bundle, and forceps minor.3,4
