Relationships between acute imaging biomarkers and theory of mind impairment in post-acute pediatric traumatic brain injury: A prospective analysis using susceptibility weighted imaging (SWI)

Abstract

Theory of Mind (ToM) forms an integral component of socially skilled behavior, and is critical for attaining developmentally appropriate goals. The protracted development of ToM is mediated by increasing connectivity between regions of the anatomically distributed 'mentalizing network', and may be vulnerable to disruption from pediatric traumatic brain injury (TBI). The present study aimed to evaluate the post-acute effects of TBI on first-order ToM, and examine relations between ToM and both local and global indices of macrostructural damage detected using susceptibility-weighted imaging (SWI). 104 children and adolescents with TBI and 43 age-matched typically developing (TD) controls under..
