Multicenter StudySeverity and outcome of traumatic brain injuries (TBI) with different causes of injury.
Most epidemiological studies and reports have reached a consensus on the leading causes of traumatic brain injury (TBI). Despite the fact that the area of TBI is relatively well studied, reports on differences in severity and outcome of TBI with different causes are lacking. ⋯ It is concluded that the causes of TBI should be considered by both clinicians and public health professionals as a lead in prognosis of outcome and policy planning.

Comparative StudyEmergency department prediction of post-concussive syndrome following mild traumatic brain injury--an international cross-validation study.
Between 20-50% of those suffering a mild traumatic brain injury (MTBI) will suffer symptoms beyond 3 months or post-concussive disorder (PCD). Researchers in Sydney conducted a prospective controlled study which identified that bedside recordings of memory impairment together with recordings of moderate or severe pain could predict those who would suffer PCS with 80% sensitivity and specificity of 76%. ⋯ This is the first study to compare populations from different countries with diverse language groups using a predictive model for identifying PCD following MTBI. The model may be able to identify an 'at risk' population to whom pre-emptive treatment can be offered.

Axis I and II psychiatric disorders in patients with traumatic brain injury: a 12-month follow-up study.
To evaluate the occurrence of axis I and II psychiatric disorders among patients with traumatic brain injury (TBI). ⋯ Both axis I and II psychiatric disorders are common among patients with TBI. Alcohol dependence and personality disorders are prevalent in individuals prone to TBI, whereas depressive disorders typically develop after injury. Psychiatric disorders should be addressed in rehabilitation, as otherwise they will hinder the recovery after TBI.

ReviewNon-impact, blast-induced mild TBI and PTSD: concepts and caveats.
A volumetric blood surge (rapid physical movement/displacement of blood) is hypothesized to cause the non-impact, mild TBI and battlefield PTSD induced by a blast over-pressure wave. ⋯ Three factors may be critical to the induction of blast-induced brain injuries: (1) the difference in pressure between the ventral body cavity and cranial cavity; (2) blood that acts as a transmission medium to propagate a pressure wave to the brain; and (3) the vulnerability of cerebral blood vessels and the BBB to a sudden fluctuation in perfusion pressure.

Association between combat stress and post-concussive symptom reporting in OEF/OIF service members with mild traumatic brain injuries.
The relationship between combat stress and post-concussive symptoms in service members with mild traumatic brain injuries (mTBI) is poorly understood. It was hypothesized that the co-occurrence of combat stress would have a significant effect on the severity of post-concussive complaints, specifically on emotional and cognitive symptoms. ⋯ The findings of the present study suggest that non-brain injury-related factors, such as high-levels of combat stress, may impact post-concussive symptom reporting in this population, further confounding the accuracy of the post-concussion syndrome (PCS) diagnosis. Considerable caution should be exercised in making the diagnosis of PCS in concussed service members with co-occurring combat-stress disorders.
