How long is too long? The lack of consensus regarding the post-concussion syndrome diagnosis.
A standard definition of Post-concussion Syndrome (PCS) does not exist. The objective was to determine consensus regarding the definition of PCS among physician members of the American College of Sports Medicine (ACSM). ⋯ There is a lack of consensus regarding the definition of PCS among physician members of the ACSM. A standard definition would improve consistency in concussion research and in clinical practise.

Analysis of S100B serum levels in different types of traumatic intracranial lesions.
The objective of this study was to determine whether the type of intracranial traumatic lesions, the number of simultaneous traumatic lesions, and the occurrence of skull and facial bone fractures have an influence on S100 calcium binding protein B (S100B) serum levels. Patients with blunt traumatic brain injury were prospectively enrolled into this cohort study over a period of 13 months. Venous blood samples were obtained prior to emergency cranial CT scan in all patients within 3 h after injury. ⋯ In patients with intracranial traumatic lesions, skull fractures, as well as skull and facial bone fractures occurring together, were identified as significant additional factors for the increase in serum S100B levels (p < 0.0001). Older age was also associated with elevated S100B serum levels (p < 0.0001). Our data show that peak S100B serum levels were found in patients with cerebral edema and brain contusions.

Mild traumatic brain injury defined by Glasgow Coma Scale: Is it really mild?
Conventionally, a Glasgow Coma Scale (GCS) score of 13-15 defines mild traumatic brain injury (mTBI). The aim of this study was to identify the factors that predict progression on repeat head computed tomography (RHCT) and neurosurgical intervention (NSI) in patients categorized as mild TBI with intracranial injury (intracranial haemorrhage and/or skull fracture). ⋯ In patients with intracranial injury, a mild GCS score (GCS 13-15) in patients with an intracranial injury does not preclude progression on repeat head CT and the need for a neurosurgical intervention. Base deficit greater than four and displaced skull fracture are the greatest predictors for neurosurgical intervention in patients with mild TBI and an intracranial injury.

White matter and reading deficits after pediatric traumatic brain injury: A diffusion tensor imaging study.
Pediatric traumatic brain injury often results in significant long-term deficits in mastery of reading ability. This study aimed to identify white matter pathways that, when damaged, predicted reading deficits in children. Based on the dual-route model of word reading, we predicted that integrity of the inferior fronto-occipital fasciculus would be related to performance in sight word identification while integrity of the superior longitudinal fasciculus would be related to performance in phonemic decoding. ⋯ No association was identified between the inferior fronto-occipital fasciculus and sight word reading or phonemic decoding. Reading fluency was associated with the integrity of the cingulum bundle. These findings support dissociable pathways predicting word reading and fluency using Diffusion Tensor Imaging and provide additional information for developing models of acquired reading deficits by specifying areas of brain damage which may predict reading deficits following recovery from the acute phase of TBI.

Child traumatic brain injury (TBI) is a major cause of disability in early life. Unlike in adults, a TBI in childhood causes an insult to a brain that is developing, potentially affecting future brain maturation, neural connectivity, and the acquisition of new skills. This review considers how such early brain insult may impact children's functional abilities, and how these processes may link with differential patterns of recovery across infancy, childhood, and adolescence. ⋯ To assist in understanding what may contribute to outcomes, we discuss predictive factors (injury severity, child and environment status) and research reporting on their individual and combined effect on recovery. The identification of such outcome predicators has led to an emerging literature in the area of intervention and rehabilitation that we also summarize. Finally, it concludes with discussion of the future direction of pediatric TBI research.
