PURPOSE To investigate longitudinal changes in global and regional brain volume in patients 1 year after mild traumatic brain injury (MTBI) and to correlate such changes with clinical and neurocognitive metrics. MATERIALS AND METHODS This institutional review board-approved study was HIPAA compliant. Twenty-eight patients with MTBI (with 19 followed up at(More)
INTRODUCTION Malaria remains a major health concern in tropical and subtropical countries. A large number of cases of malaria have been reported from the State of Orissa, India. Severe malaria cases are reported throughout the year, but they are more common during the high transmission season. The last decade has witnessed a changing pattern of(More)
The automated laboratory systems described in this paper were developed for use at the National Center for Toxicological Research (NCTR) and each of five collaborating laboratories. These laboratories participated in a study designed to evaluate the intra- and interlaboratory reliability and sensitivity of several behavioral test methods used in(More)
OBJECTIVE To compare the relative utility of conventional neuropsychological and social problem-solving approaches to measuring functional problem solving deficits in individuals with acquired brain damage (ABD). DESIGN In Study I, scores for individuals with ABD were compared to scores for control and normative samples. In Study II, pre- and posttest(More)
Three inter-related studies examine the construct of problem solving as it relates to the assessment of deficits in higher level outpatients with traumatic brain injury (TBI). Sixty-one persons with TBI and 58 uninjured participants completed measures of problem solving and conceptually related constructs, which included neuropsychological tests,(More)
BACKGROUND The field of positive psychology has grown exponentially within the last decade. To date, however, there have been few empirical initiatives to clarify the constructs within positive psychology as they relate to rehabilitation medicine. Character strengths, and in particular resilience, following neurological trauma are clinically observable(More)
PRIMARY OBJECTIVE To determine if individuals with brain injury can modify heart rate variability (HRV) through biofeedback and, if so, enhance its pattern to improve emotional regulation and problem-solving ability. DESIGN A quasi-experimental design with repeated measures was employed. Thirteen individuals aged 23-63 years with severe brain injury(More)
OBJECTIVE The goal of this paper is to illustrate how the lessons learned in over 20 years of randomized clinical trials have advanced cognitive rehabilitation beyond traditional approaches to problem solving by more explicitly integrating subjective self-appraisal factors in routine clinical practice. RESULTS The concept of problem orientation, as(More)
Purpose. While diffusion MRI has been extremely promising in the study of MTBI, identifying patients with recent MTBI remains a challenge [1]. The literature is mixed with regard to localizing injury in these patients, however, gray matter such as the thalamus and white matter including the corpus callosum and frontal deep white matter have been repeatedly(More)
OBJECTIVE Cognitive and emotional symptoms are primary causes of long-term functional impairment after acquired brain injury (ABI). Although the occurrence of post-ABI emotional difficulties is well-documented, most investigators have focused on the impact of depression on functioning after ABI, with few examining the role of anxiety. Knowledge of the(More)
