This study meta-analyzed research examining relationships between diffusion tensor imaging and cognition following pediatric traumatic brain injury (TBI). Data from 14 studies that correlated fractional anisotropy (FA) or apparent diffusion coefficient/mean diffusivity with cognition were analyzed. Short-term (<4 weeks post-TBI) findings were inconsistent, but, in the medium to long term, FA values for numerous large white matter tracts and the whole brain were related to cognition. However, the...

Impairment in executive function (EF) is commonly found in Alzheimer’s Dementia (AD) and Mild Cognitive Impairment (MCI). Atlas-based Diffusion Tensor Imaging (DTI) methods may be useful in relating regional integrity to EF measures in MCI and AD. 66 participants (25 NC, 22 MCI, and 19 AD) received DTI scans and clinical evaluation. DTI scans were applied to a pre-segmented atlas and fractional anisotropy (FA) and mean diffusivity (MD) were calculated. ANOVA was used to assess group differences ...

Objective Novel biomarkers for monitoring progression in neurodegenerative conditions are needed. Measurement of microstructural changes in white matter (WM) using diffusion tensor imaging (DTI) may be a useful outcome measure. Here we report trajectories of WM change using serial DTI in a cohort with behavioral variant frontotemporal dementia (bvFTD). Methods Twenty-three patients with bvFTD (12 having genetic mutations), and 18 age-matched control participants were assessed using DTI and neuro...

Cognitive dysfunction is the leading cause of disability following traumatic brain injury (TBI). This article provides a review of the cognitive sequelae of TBI, with a focus on deficits of executive functioning and everyday thinking skills. The pathophysiology, assessment, and treatment of TBI-related cognitive problems are also discussed. Language: en

While memory deficits are consistently found to be a salient problem in individuals with moderate to severe traumatic brain injury (TBI), the specific memory processes (i.e., encoding, consolidation, and retrieval) underlying the verbal memory deficit are disputed in the literature. The current study evaluated the recovery of these verbal memory processes over time. A TBI patient group evaluated acutely after the injury (baseline) and again at 6 months and 1 year post injury was compared to a de...

I present an account of the origins and development of the multicomponent approach to working memory, making a distinction between the overall theoretical framework, which has remained relatively stable, and the attempts to build more specific models within this framework. I follow this with a brief discussion of alternative models and their relationship to the framework. I conclude with speculations on further developments and a comment on the value of attempting to apply models and theories be...

OBJECTIVE:: To determine whether the Traumatic Brain Injury Model Systems National Database (TBIMS-NDB) is representative of individuals aged 16 years and older admitted for acute, inpatient rehabilitation in the United States with a primary diagnosis of traumatic brain injury (TBI). DESIGN:: Secondary analysis of existing data sets. SETTING:: Acute inpatient rehabilitation facilities. PARTICIPANTS:: Patients aged 16 years and older with a primary rehabilitation diagnosis of TBI. MAIN OUTCOME ME...

Proceeding from the assumptions that specific frontal regions control discrete functions and that very basic cognitive processes can be systematically manipulated to reveal those functions, recent reports have demonstrated consistent anatomical/functional relationships: dorsomedial for energization, left dorsolateral for task setting, and right dorsolateral for monitoring. There is no central executive. There are, instead, numerous domain general processes discretely distributed across several f...

Traumatic brain injuries arise from open or closed head injuries. Most traumatic brain injuries result from closed head injuries (an example of an open head injury is an object penetrating the skull). Brain injuries occur as the result of acceleration-deceleration forces (linear or angular), blunt trauma, or both. Traumatic brain injuries occur on a broad continuum of severity, from very mild transient injuries to catastrophic injuries resulting in death or severe disability. The continuum of se...

We applied the item-specific deficit approach (ISDA) to California Verbal Learning Test data obtained from 56 severe, acceleration–deceleration closed head injury (CHI) participants and 62 controls. The CHI group demonstrated deficits on all ISDA indices in comparison to controls. Regression analyses indicated that encoding deficits, followed by consolidation deficits, accounted for most of the variance in delayed recall. Additionally, level of acquisition played a partial role in CHI-associated...
