Comparative StudyTo exclude or not to exclude: white matter hyperintensities in diffusion tensor imaging research.
A practical methodological issue for diffusion tensor imaging (DTI) researchers is determining what to do about incidental findings, such as white matter hyperintensities (WMHI). The purpose of this study was to compare healthy control subjects with or without WMHIs on whole brain DTI. ⋯ The decision to include or exclude subjects who have incidental findings can influence the results of a study.

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.

Case ReportsSource imaging of QEEG as a method to detect awareness in a person in vegetative state.
Assessment of awareness in patients with severe brain injury remains subjective, although patients with even limited awareness (e.g. minimal conscious state, MCS) have different prognoses and treatment than those in vegetative state (VS). Recently, task appropriate differential regional activation in VS has been reported using fMRI during mental imagery. ⋯ Results from this single case suggests the potential utility of QEEG source localization images to detect awareness in patients clinically diagnosed as being in VS. This indicates the possibility that EEG may serve as an important adjunct to the assessment of awareness in patients with disorders of consciousness in the clinical setting.

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.

Validation of the Abbreviated Westmead Post-traumatic Amnesia Scale: a brief measure to identify acute cognitive impairment in mild traumatic brain injury.
To validate the use of the Abbreviated Westmead Post-traumatic Amnesia Scale (A-WPTAS) in the assessment of acute cognitive impairment in mild traumatic brain injury (mTBI). ⋯ The A-WPTAS is a valid measure. The A-WPTAS may reduce the risk of failing to classify patients with mTBI by identifying and documenting acute cognitive impairment.
