To evaluate whether indices of preinjury health and functioning are associated with risk of incident traumatic brain injury (TBI) with loss of consciousness (LOC) and to evaluate health-related factors associated with mortality in individuals with incident TBI. ⋯ Indices of health, mood, and functional status predict incident TBI with LOC in older adults. These findings may have implications for injury prevention and postinjury clinical management.

OBJECTIVE Sport-related concussion (SRC) has emerged as a public health problem, especially among student-athletes. Whereas most concussions resolve by 2 weeks, a minority of patients experience postconcussion syndrome (PCS), in which symptoms persist for months. The objective of this study was to elucidate factors predictive of PCS among a sample of National Collegiate Athletic Association (NCAA) student-athletes in the academic years 2009-2010 to 2014-2015. ⋯ CONCLUSIONS Postconcussion syndrome represents one of the most impactful sequelae of SRC. In this study of exclusively collegiate student-athletes, the authors found that recurrent concussions and various concussion-related symptoms were associated with PCS. The identification of initial risk factors for the development of PCS may assist sports medicine clinicians in providing timely interventions and treatments to prevent morbidity and shorten recovery time after SRC.

Traumatic brain injury increases the risk of both early and late seizures. Antiepileptic prophylaxis reduces early seizures, but their use beyond 1 week does not prevent the development of post-traumatic epilepsy. Furthermore, prolonged prophylaxis exposes patients to side effects of the drugs and has occupational implications. The American Academy of Neurology recommends that antiepileptic prophylaxis should be started for patients with severe traumatic brain injury and discontinued after 1 week. An audit is presented here that investigates the use of prophylaxis in a cohort of military patients admitted to the UK Defence Medical Rehabilitation Centre (DMRC). ⋯ The use of antiepileptic prophylaxis varies widely and is generally inconsistent with evidence-based guidance. This exposes some patients to a higher risk of early seizures and others to unnecessary use of antiepileptics. Better implementation of prophylaxis is required.

Theory of mind mediates the prospective relationship between abnormal social brain network morphology and chronic behavior problems after pediatric traumatic brain injury.
Childhood and adolescence coincide with rapid maturation and synaptic reorganization of distributed neural networks that underlie complex cognitive-affective behaviors. These regions, referred to collectively as the 'social brain network' (SBN) are commonly vulnerable to disruption from pediatric traumatic brain injury (TBI); however, the mechanisms that link morphological changes in the SBN to behavior problems in this population remain unclear. In 98 children and adolescents with mild to severe TBI, we acquired 3D T1-weighted MRIs at 2-8 weeks post-injury. ⋯ Mediation analysis indicated that impaired theory of mind mediated the prospective relationship between abnormal SBN morphology and more frequent chronic behavior problems. Our findings suggest that sub-acute alterations in SBN morphology indirectly contribute to long-term behavior problems via their influence on ToM. Volumetric change in the SBN and its putative hub regions may represent useful imaging biomarkers for prediction of post-acute social cognitive impairment, which may in turn elevate risk for chronic behavior problems.

Case ReportsDoes pain relief influence recovery of consciousness? a case report of a patients treated with ziconotide.
For people with cervical spinal cord injury (SCI), access to computers can be difficult, thus several devices have been developed to facilitate their Disorders of consciousness (DOC) are difficult to classify. The degree of consciousness varies from coma to vegetative state or unresponsive wakefulness syndrome (UWS) and minimally conscious state. Correct diagnosis has important ethical and legal implications, and pain may be cause of misdiagnosis. ⋯ Anecdotal reports of improved consciousness with intrathecal baclofen therapy may be due to pain relief. Reduction of pain in DOC is important and drugs should not interfere with cognition, and must be effective and manageable. Ziconotide may be one of the possible candidate due to its synergistic antispastic action in combination with baclofen when an intratecal pump has been implanted.
