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)
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)
The effects of repeated exposure to cold temperature on cognitive performance were examined in 10 male subjects who were exposed to control (25 degrees C) and cold (10 degrees C) conditions on 10 successive days. A cognitive test battery (ANAM-ICE) was administered each day to assess complex and simple cognitive functioning accuracy, efficiency and response(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)
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 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)
The ARES (ANAM Readiness Evaluation System) is a cognitive testing system designed for operation on palm OS handheld computers i.e., Personal Digital Assistants (PDA). It provides an inexpensive and portable testing platform for field and clinical applications. ARES test batteries can be configured from a library of tests derived from the ANAM test system.(More)
The objective of this study was to determine whether inconsistent and erratic within-day and across-day performance is a symptom of mild to moderate traumatic brain injury (TBI), and to determine whether impaired consistency of performance can coexist, in the same patient, with intact or "normal" performance on single administrations of neuropsychological(More)
OBJECTIVE The objective of this study was to determine whether an adolescent athlete, in the absence of concussion, would be expected to show an improvement in cognitive function during the course of a high school football season. BACKGROUND At least 60,000 American high school football players suffer cerebral concussion every year, and symptoms may(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)
