Multicenter Study Comparative StudyNeuroanatomical basis of paroxysmal sympathetic hyperactivity: a diffusion tensor imaging analysis.
Paroxysmal sympathetic hyperactivity (PSH) is observed in a sub-set of patients with moderate-to-severe traumatic brain injury (TBI). The neuroanatomical basis of PSH is poorly understood. It is hypothesized that PSH is linked to changes in connectivity within the central autonomic network. ⋯ Disconnection involving the posterior corpus callosum and of the posterior limb of the internal capsule may play a role in the pathogenesis or expression of PSH.

Multicenter StudySerum visinin-like protein-1 in concussed professional ice hockey players.
Visinin-like protein-1 (VILIP-1) has shown potential utility as a biomarker for neuronal injury in cerebrospinal fluid. This study investigated serum VILIP-1 as a diagnostic and prognostic marker in sports-related concussion. ⋯ These results provide evidence that serum VILIP-1 may not be a useful biomarker for diagnosis and prognosis of sports-related concussion.

Multicenter Study Comparative StudySustained outcomes following mild traumatic brain injury: results of a five-emergency department longitudinal study.
To report on the occurrence of sustained outcomes including post-concussion symptoms, health services used and indicators of social disruption following a mild traumatic brain injury (MTBI). ⋯ These findings argue that some with an MTBI suffer real complaints and they are sustained from 3 to at least 6 months. More effort should be given toward specificity of these symptoms from those reported by members of the comparison group.

Multicenter StudyRecognition of facial and vocal affect following traumatic brain injury.
Studies of facial affect recognition by people with traumatic brain injury (TBI) have shown this to be a significant problem. Vocal affect recognition also appears to be challenging for this population, but little is known about the degree to which one modality is impaired compared to the other. This study compared facial and vocal affect recognition of high and low intensity emotion expressions in people with moderate-to-severe TBI. ⋯ The degree of facial affect impairment was significantly greater than vocal affect impairment in this sample of people with moderate-to-severe TBI. Low intensity emotion expressions were particularly problematic and an advantage for positively valenced facial emotion expressions was indicated.

Multicenter StudyPredictors of child post-concussion symptoms at 6 and 18 months following mild traumatic brain injury.
A proportion of children will experience persistent post-concussion symptoms (PCS) following a mild traumatic brain injury (mTBI). As persistent PCS may be maintained by pathological and psychological factors, this study aimed to describe and evaluate potential pre- and post-injury parent and child predictors of persistent PCS. ⋯ Children at risk of persistent PCS can be identified by higher levels of pre- and post-injury PCS, parent distress and poorer post-injury cognition. These factors should be addressed by interventions aimed at minimizing the occurrence and impact of child PCS.
