Disconnectome-symptom mapping (DSM) was used to identify relationships between brain and behaviour, by assessing the effect of pathology-intersected white matter tracts on neuropsychological outcomes. This study used DSM to see how IQ, two years post-injury, related to disconnections in the brain, following paediatric traumatic brain injury. For this, two approaches were employed: the BCBtoolkit, designed for use in adults, and a child-analogue. This study found the BCBtoolkit to be less sensitive than the child-analogue, however, in both methods, disconnections in the superior longitudinal fasciculus and external capsule correlated with a reduced IQ when comparing disconnected patients to controls.
