Subjective and Objective Assessment of Sleep in Adolescents with Mild Traumatic Brain Injury.
There is increased recognition that sleep problems may develop in children and adolescents after mild traumatic brain injury (mTBI). However, few studies have utilized both subjective and objective measures to comprehensively assess sleep problems in the pediatric population following the acute post-TBI period. The aims of this study were to compare sleep in adolescents with mTBI to healthy adolescents using subjective and objective measures, and to identify the clinical correlates associated with sleep problems. ⋯ Our findings suggest that adolescents may experience subjective and objective sleep disturbances up to one year following mTBI. These findings require further replication in larger samples. Additionally, research is needed to identify possible mechanisms for poor sleep in youth with mTBI.

The aim of our study was to evaluate the clinical outcomes in patients on preinjury Ibuprofen with traumatic brain injury. ⋯ In a matched cohort of trauma patients, preinjury Ibuprofen use was not associated with progression of initial intracranial hemorrhage and the need for neurosurgical intervention. Preinjury use of Ibuprofen as an independent variable should not warrant the need for a routine RHCT scan.

Decompressive craniectomy reduces white matter injury following controlled cortical impact in mice.
Reduction and avoidance of increases in intracranial pressure (ICP) after severe traumatic brain injury (TBI) continue to be the mainstays of treatment. Traumatic axonal injury is a major contributor to morbidity after TBI, but it remains unclear whether elevations in ICP influence axonal injury. Here we tested the hypothesis that reduction in elevations in ICP after experimental TBI would result in decreased axonal injury and white matter atrophy in mice. ⋯ At 4 weeks post-injury, Open animals had an 18% reduction in white matter volume compared with 34% in Closed animals (p<0.01). Thus, our results indicate that CCI with decompressive craniectomy was associated with reductions in ICP and reduced pericontusional axonal injury and white matter atrophy. If similar in humans, therapeutic interventions that ameliorate intracranial hypertension may positively influence white matter injury severity.

To determine the ability of the modified (Spanish) version of the Simplified Motor Score (mSMS) to predict adverse events during hospitalization and to compare its predictive ability to that of the Glasgow Coma Scale (GCS) in adults with head injuries treated outside the hospital. ⋯ Although the ability of the mSMS to predict in-hospital adverse outcomes is good, it is inferior to the GCS in adults with head injuries attended outside the hospital.

Low-level laser therapy for traumatic brain injury in mice increases brain derived neurotrophic factor (BDNF) and synaptogenesis.
Transcranial low-level laser (light) therapy (LLLT) is a new non-invasive approach to treating a range of brain disorders including traumatic brain injury (TBI). We (and others) have shown that applying near-infrared light to the head of animals that have suffered TBI produces improvement in neurological functioning, lessens the size of the brain lesion, reduces neuroinflammation, and stimulates the formation of new neurons. In the present study we used a controlled cortical impact TBI in mice and treated the mice either once (4 h post-TBI, 1-laser), or three daily applications (3-laser) with 810 nm CW laser 36 J/cm(2) at 50 mW/cm(2). ⋯ The data suggest that the benefit of LLLT to the brain is partly mediated by stimulation of BDNF production, which may in turn encourage synaptogenesis. Moreover the pleiotropic benefits of BDNF in the brain suggest LLLT may have wider applications to neurodegenerative and psychiatric disorders. Neurological Severity Score (NSS) for TBI mice.
