The Galveston Orientation and Amnesia Test (GOAT) was developed to evaluate cognition serially during the subacute stage of recovery from closed head injury. This practical scale measures orientation to person, place, and time, and memory for events preceding and following the injury. The distribution of test scores in 50 patients who had recovered from a(More)
BACKGROUND Despite normal CT imaging and neurologic functioning, many individuals report postconcussion symptoms following mild traumatic brain injury (MTBI). This dissociation has been enigmatic for clinicians and investigators. METHODS Diffusion tensor imaging tractography of the corpus callosum was performed in 10 adolescents (14 to 19 years of age)(More)

This action might occur both at the cortical level and in subcortical structures such as basal ganglia. 7. On the basis of a series of related studies [A. Bechara, D. Tranel, H. Damasio, S.(More)
The primary objective of this review is to examine the methodology and evidence for neuroplasticity operating in recovery from traumatic brain injury (TBI), as compared with previous findings in patients sustaining perinatal and infantile focal vascular lesions. The evidence to date indicates that the traditional view of enhanced reorganization of function(More)
BACKGROUND AND PURPOSE DTI of normal-appearing WM as evaluated by conventional MR imaging in mTBI has the potential to identify important regional abnormalities that relate to PCS. VBA was used to examine WM changes in acute mTBI. MATERIALS AND METHODS WM was assessed between 1 and 6 days postinjury with voxel-based DTI analyses in 10 adolescent patients(More)
Neuropsychological outcome was evaluated in a prospective, longitudinal follow-up study of children age 4 months to 7 years at injury with either mild-to-moderate (N = 35) or severe (N = 44) traumatic brain injury (TBI). Age-appropriate tests were administered at baseline, 6 months, 12 months, and 24 months after the injury. Performance was compared on (1)(More)
This paper reviews research concerning impairment of memory during the early and late stages of recovery from closed-head injury (CHI). Posttraumatic and retrograde amnesia are discussed, including direct measurement, rate of forgetting and evoked potential correlates. Studies of residual memory deficit in survivors of CHI are reviewed, including the(More)
OBJECTIVE To determine whether an association exists between traumatic brain injury (TBI) sustained in adulthood and cognitive impairment 6 months or longer after injury. DESIGN Systematic review of the published, peer-reviewed literature. RESULTS From 430 articles, we identified 11 primary and 22 secondary studies that examined cognitive impairment by(More)
The selective reminding (SR) procedure, a popular technique for the study of verbal memory, was used to investigate aspects of memory functioning in a large group of normal elderly and in a smaller group of elderly subjects with Alzheimer Type Dementia (ATD). One hundred thirty-four normal elderly (mean age = 79.53 years) subjects and 21 ATD subjects (mean(More)
BACKGROUND We investigated the cognitive and psychiatric outcome 6 months after bilateral subthalamic nucleus deep brain stimulation (DBS) for the treatment of Parkinson's disease (PD) using a disease control group. METHODS 23 patients who underwent DBS were compared with 28 medically treated patients with PD at baseline and at 6 months for(More)
