A 4-year longitudinal study of the cognitive effects of the Chernobyl nuclear accident was conducted from 1995 to 1998. The controls were healthy Ukrainians residing several hundred kilometers away from Chernobyl. The exposed groups included Eliminators, Forestry workers and Agricultural workers living within 150 km of Chernobyl. Accuracy and efficiency of(More)
This exploratory study was conducted to increase understanding of neuropsychological test performance in those with blast-related mild traumatic brain injury (mTBI). The two variables of interest for their impact on test performance were presence of mTBI symptoms and history of posttraumatic stress disorder (PTSD). Forty-five soldiers postblast mTBI, 27(More)
This paper presents a historical overview and current perspective of the Automated Neuropsychological Assessment Metrics (ANAM) test system. We discuss the history of its development along with a synopsis of the evolution of computerized testing that has occurred and led to ANAM over the past 30 years within the Department of Defense (DoD). We include a(More)
OBJECTIVE We sought to determine the duration of cognitive impairment after sports concussion. METHODS We conducted a study with a prospective design in which 729 athletes underwent preseason baseline testing by being administered a computerized neuropsychological test battery, followed by retesting at regular intervals after they sustained sports-related(More)
The present study examines the relation between a set of computerized neuropsychological measures, Automated Neuropsychological Assessment Metrics (ANAM), and a set of traditional clinical neuropsychological tests. Both sets of tests have been employed in recent studies of mild brain injury. Factor analysis and stepwise regression indicate that both sets of(More)

A baseline computerized cognitive assessment was completed by 483 military cadets before their initial school year. Fourteen cadets concussed during physical education boxing were retested <1 hour after injury and again on return to full activity 4 days later. Compared with baseline testing, postinjury performance on simple reaction time and continuous(More)
This paper describes the development and ongoing validation of the ANAM-sports medicine battery (ASMB) for use in concussion surveillance and management. A review of previous research utilizing the ASMB highlights current issues in concussion surveillance including: tracking cognitive recovery, effect of previous concussion history on acute concussion(More)
