Neuropsychological tests are often used to evaluate executive function (EF) deficits in patients suffering traumatic brain injuries (TBIs). This study compared the sensitivity of three such tests--namely, the Delis-Kaplan Executive Function System Sorting Test (D-KEFS ST), the Wisconsin Card Sorting Test (WCST), and the Trail Making Test (TMT)--in… (More)
Which verbal fluency measure is most useful in demonstrating executive deficits after traumatic brain injury?
Traumatic brain injury (TBI) is the most common cause of brain damage, resulting in long-term disability. The "reserve" construct has been proposed to account for the reported mismatch between brain damage and its clinical expression. Although numerous studies have used various measures thought to reflect this construct, few studies have examined its… (More)
The concept of "reserve" has been proposed to account for the mismatch between brain pathology and its clinical expression. Prior efforts to characterize this concept focused mostly on brain or cognitive reserve measures. The present study was a preliminary attempt to evaluate premorbid personality and emotional aspects as potential moderators in… (More)
OBJECTIVE Traumatic brain injury (TBI) is the most common cause of brain damage, resulting in long-term disability. The ever increasing life expectancies among TBI patients necessitate a critical examination of the factors that influence long-term outcome. Our objective was to evaluate the contribution of premorbid factors (which were identified in our… (More)
This paper examines switching and clustering in phonemic and semantic fluency tasks in individuals with traumatic brain injury (TBI). Fluency tasks were administered to 30 Hebrew-speaking patients with TBI and 30 age-matched control participants. Significant group differences were found in total output, number of switches, and number of clusters on both… (More)
Regressive behavior is a known sequela after severe traumatic brain injury (TBI). However, prolonged "infantile-like" behavior has received little attention in the literature, suggesting that this is a rare phenomenon. It is typically characterized by long-lasting childish, extremely dependent, and sometimes aggressive behavior, which is distinguished from… (More)
