OBJECTIVE: Changes in functional network connectivity following traumatic brain injury (TBI) have received increasing attention in recent neuroimaging literature. This study sought to understand how disrupted systems adapt to injury during resting and goal-directed brain states. Hyperconnectivity has been a common finding, and dedifferentiation (or loss of segregation of networks) is one possible explanation for this finding. We hypothesized that individuals with TBI would show dedifferentiation of networks (as noted in other clinical populations) and these effects would be associated with cognitive dysfunction...

To investigate the effect of cranioplasty on rehabilitation of post-traumatic brain injury (TBI) patients, 37 patients with TBI were arranged by retrospectively assessment study. Those TBI patients receiving in-hospital rehabilitation in the Department of Rehabilitation in a medical center of South Taiwan from 2010 to 2015 were assigned into two groups: A and B. All patients entered the multidisciplinary holistic in-patient rehabilitation training for about 1 month. Patients in Group A received decompressive craniectomy (DC), patients in Group B received DC and cranioplasty...

Clinical investigations of individuals with chronic stage traumatic brain injury (TBI) showing mild-to-moderate levels of residual impairment largely use standardized neuropsychological assessments to measure executive functioning. The Hayling Sentence Completion Test (HSCT) relies upon several executive functions but detects cognitive impairments across studies inconsistently. We sought to (a) further characterize sentence completions on the HSCT by quantifying their semantic and lexical properties and (b) investigate cognitive components important for HSCT performance...

This study examined the role of injury-related variables, socioeconomic disadvantage, and preexisting conditions on verbal learning and memory in a sample of children with traumatic brain injury (TBI). We also explored the mediating effect of processing speed and working memory. One hundred children aged 7-16 years (M = 13.46, SD = 2.78) completed a neuropsychological assessment between 1-12 months post injury. Hierarchical multiple regression analyses were conducted on domains comprising the four-factor model of the California Verbal Learning Test-Children's Version (CVLT-C)...

The Glasgow Outcome Scale-Extended (GOSE) is often the primary outcome measure in clinical trials for traumatic brain injury (TBI). Although the GOSE's capture of global function outcome has several strengths, concerns have been raised about its limited ability to identify mild disability and failure to capture the full scope of problems patients exhibit after TBI. This analysis examined the convergence of disability ratings across a multidimensional set of outcome domains in the Transforming Research and Clinical Knowledge in Traumatic Brain Injury (TRACK-TBI) Pilot study...

BACKGROUND: Mild traumatic brain injury (MTBI) represents 70-80% of all treated brain injuries. A considerable proportion of MTBI patients experience post-concussion symptoms for a prolonged period after MTBI, and these symptoms are diagnosed as persistent post-concussion syndrome (PPCS). PPCS is defined as a range of physical, cognitive, and emotional symptoms. However, memory and executive dysfunction seems to be one of the most debilitating symptoms. Recently, non-invasive brain stimulation has been studied as a potential treatment method for traumatic brain injury (TBI) patients...

Concordance validity of commonly used performance validity tests (PVTs) was assessed in a sample of Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn (OEF/OIF/OND) veterans referred to an mTBI screening clinic in a south-eastern Veterans Affairs hospital. Veteran service members (total n = 184) completed the Rey-15, Repeatable Battery of the Assessment for Neuropsychological Status Effort Index (RBANS EI), and Reliable Digit Span (RDS) from the Wechsler Intelligence Scales. Kappa coefficients and percentage of agreement were established to determine the level of concordance between the three measures...

The long-term effects of blast exposure are a major health concern for combat veterans returning from the recent conflicts in Iraq and Afghanistan. We used an optimized diffusion tensor imaging tractography algorithm to assess white matter (WM) fractional anisotropy (FA) in blast-exposed Iraq and Afghanistan veterans (n = 40) scanned on average 3.7 years after deployment/trauma exposure. Veterans diagnosed with a blast-related mild traumatic brain injury (mTBI) were compared to combat veterans with blast exposure but no TBI diagnosis...

Accelerated long-term forgetting (ALF) is characterized by adequate recall after short, but not long delays. ALF is not detected by standardized neuropsychological memory tests. Currently, the prevailing conceptualization of ALF is of a temporal lobe seizure-related phenomenon. Nevertheless, Mayes and colleagues (2003) proposed that ALF may occur when any of the components of the brain network involved in long-term memory formation, or their interaction, is disrupted. This disruption does not have to be caused by temporal lobe seizures for ALF to occur...

OBJECTIVES: To dissociate injury-related factors from psychological contributions to impaired awareness of deficits following traumatic brain injury (TBI); impaired awareness is theorized to partly reflect psychological factors (e.g., denial), but empirical evidence for this theory is scarce. DESIGN: We examined how different factors predict awareness in patients undergoing rehabilitation (N = 43). Factors included (1) neurological (injury severity), (2) neuropsychological loss, (3) psychological (denial, projection, identification), and (4) personality (narcissism)...

OBJECTIVE: Performance validity tests (PVTs) and symptom validity tests (SVTs) are often administered during neuropsychological evaluations. Examinees may be coached to avoid detection by measures of response validity. Relatively little research has evaluated whether graduated levels of coaching has differential effects upon PVT and SVT performance. Accordingly, the present experiment evaluated the effect of graduated levels of coaching upon the classification accuracy of commonly used PVTs and SVTs and the currently accepted criterion of failing two or more PVTs or SVTs...

OBJECTIVES: The negative effect of changes in social behavior following traumatic brain injury (TBI) are known, but much less is known about the neuropsychological impairments that may underlie and predict these changes. The current study investigated possible associations between post-injury behavior and neuropsychological competencies of emotion recognition, understanding intentions, and response selection, that have been proposed as important for social functioning. METHODS: Forty participants with TBI and 32 matched healthy participants completed a battery of tests assessing the three functions of interest...

REVIEW
Jason R Soble, Edan A Critchfield, Justin J F O'Rourke
Clinical neuropsychology is a subspecialty of professional psychology that is concerned with the scientific study and clinical application of brain-behavior relationships. Broadly defined, a neuropsychological evaluation is a flexible clinical tool that involves integration of objective, psychometric test data along with various other sources of clinical information to comprehensively elucidate the cognitive, behavioral, and emotional sequelae after traumatic brain injury (TBI). In addition to characterizing TBI sequelae, evidenced-based neuropsychological assessment can contribute to TBI patient care by aiding with prognostic assessment, measuring interval change/recovery over time (eg, resolution of posttraumatic amnesia), informing and implementing rehabilitation strategies, and evaluating the effectiveness of interventions...
