Clinical TrialEvaluating the impact of treatment for sleep/wake disorders on recovery of cognition and communication in adults with chronic TBI.
To longitudinally examine objective and self-reported outcomes for recovery of cognition, communication, mood and participation in adults with traumatic brain injury (TBI) and co-morbid post-traumatic sleep/wake disorders. ⋯ These results add to a small but growing body of evidence that sleep/wake disorders associated with TBI exacerbate trauma-related cognitive, communication and mood impairments. Treatment for sleep/wake disorders may optimize recovery and outcomes.

Review Case ReportsSkull stab wound from a metal railroad nail perforating the right frontal lobe.
Case report and review of literature. ⋯ Skull and brain stab wound lesions are highly infrequent, but evaluating the mechanism of injury and the successful medical and surgical treatment employed is illustrative of how post-traumatic recovery of this severe head injury can be achieved. The site of the injury and the position of the object were decisive for establishing an adequate diagnosis and prognosis. The patient reported an exemplary recovery without any secondary complications.

Serial monitoring of CO2 reactivity following sport concussion using hypocapnia and hypercapnia.
This study examined the effects of mild traumatic brain injury (mTBI) on cerebrovascular reactivity (CVR). ⋯ These data suggest that, following mTBI: (1) CVR is not impaired at rest; (2) CVR is impaired in response to respiratory stress; and (3) the impairment may be resolved as early as 4 days post-injury.

Comparative Study Controlled Clinical TrialEffects of dexmedetomidine on cerebral blood flow in critically ill patients with or without traumatic brain injury: a prospective controlled trial.
To examine the effect of dexmedetomidine on CBF in critical ill patients with or without TBI. ⋯ Dexmedetomidine may be used in patients with TBI without risk of affecting brain oxygenation.

Comparative StudyDoes a 20 minute cognitive task increase concussion symptoms in concussed athletes?
The purpose of the present study was to examine if concussion symptoms worsened immediately (i.e. 20 minutes) following performance on a computerized neurocognitive test. ⋯ The current study suggests that there may be an increase in concussion symptoms following a 20-minute cognitive task. Thus, it illustrates the need for clinicians to make sure they are symptom free with both physical and cognitive testing.
