Clinical trials aimed at developing therapies for traumatic brain injury (TBI) require outcome measures that are reliable, validated, and easily administered. The most widely used of these measures, the Glasgow Outcome Scale (GOS) and the GOS-Extended (GOS-E), have been criticized as suffering from ceiling effects. In an attempt to develop a more useful and(More)
BACKGROUND Transient paroxysmal alterations of consciousness or behavior are common sequelae of moderate and severe traumatic brain injury (TBI). Clinicians caring for patients with such episodes often diagnose them as epileptic seizures, a frequent and well-studied complication of TBI. As it is difficult to confirm this diagnosis, antiepileptic drugs are(More)
Traumatic brain injury (TBI) is associated with an increased risk of depressive symptoms. Recent imaging studies on spontaneous depression have implicated several brain structures; however, few studies have done the same for post-TBI depression. We report on a pilot observational study correlating atrophy of brain regions of interest in subjects after TBI(More)
OBJECTIVE To determine whether older persons are at increased risk for progressive functional decline after traumatic brain injury (TBI). DESIGN Longitudinal cohort study. SETTING Traumatic Brain Injury Model Systems (TBIMS) rehabilitation centers. PARTICIPANTS Subjects enrolled in the TBIMS national dataset. INTERVENTIONS Not applicable. MAIN(More)
The existing gold standard for diagnosing a suspected previous mild traumatic brain injury (mTBI) is clinical interview. But it is prone to bias, especially for parsing the physical versus psychological effects of traumatic combat events, and its inter-rater reliability is unknown. Several standardized TBI interview instruments have been developed for(More)
OBJECTIVE To test whether improved functional status correlates with more depressive symptoms after traumatic brain injury (TBI). This is based on the concept that increasing awareness of deficits may exacerbate depression, even while survivors are making functional improvements. PARTICIPANTS A total of 471 individuals with TBI (72% white; 71% men; median(More)
PRIMARY OBJECTIVE Cerebral oedema is a common complication of traumatic brain injury (TBI). The use of Fluid-Attenuated Inversion Recovery (FLAIR) imaging in combination with Diffusion Weighted Imaging (DWI) has the potential to distinguish between cytotoxic and vasogenic oedema. This study hypothesized a significant relationship between cytotoxic lesion(More)
OBJECTIVE To determine whether race/ethnicity and proficiency with the English language influence access to rehabilitation services, and ultimately outcome after traumatic brain injury (TBI). DESIGN A retrospective correlational investigation. SETTING AND PARTICIPANTS Postrehabilitation outpatients with blunt TBI. A total of 476 patients were examined 6(More)
