A Comparison of Four Computerized Neurocognitive Assessment Tools to a Traditional Neuropsychological Test Battery in Service Members with and without Mild Traumatic Brain Injury

AbstractObjectives: The aim of this study was to evaluate the reliability and validity of three computerized neurocognitive assessment tools (CNTs; i.e., ANAM, DANA, and ImPACT) for assessing mild traumatic brain injury (mTBI) in patients recruited through a level I trauma center emergency department (ED). Methods: mTBI (n=94) and matched trauma control (n=80) subjects recruited from a level I trauma center emergency department completed symptom and neurocognitive assessments within 72 hr of injury and at 15 and 45 days post-injury. Concussion symptoms were also assessed via phone at 8 days post-injury. Results: CNTs did not differentiate between groups at any time point (e.g., M 72-hr Cohen’s d=−.16, .02, and .00 for ANAM, DANA, and ImPACT, respectively; negative values reflect greater impairment in the mTBI group). Roughly a quarter of stability coefficients were over .70 across measures and test–retest intervals in controls. In contrast, concussion symptom score differentiated mTBI vs. control groups acutely), with this effect size diminished over time (72-hr and day 8, 15, and 45 Cohen’s d=−.78, −.60, −.49, and −.35, respectively). Conclusions: The CNTs evaluated, developed and widely used to assess sport-related concussion, did not yield significant differences between patients with mTBI versus other injuries. Symptom scores better differentiated groups than CNTs, with effect sizes weaker than those reported in sport-related concussion studies. Nonspecific injury factors, and other characteristics common in ED settings, likely affect CNT performance across trauma patients as a whole and thereby diminish the validity of CNTs for assessing mTBI in this patient population.

Abstract Background: Mild traumatic brain injury (mTBI) is recognized as the signature injury of the current conflicts in Iraq and Afghanistan, yet there remains limited understanding of the persisting cognitive deficits of mTBI sustained in combat. Speech-language pathologists (SLPs) have traditionally been responsible for evaluating and treating the cognitive-communication disorders following severe brain injuries. The evaluation instruments historically used are insensitive to the subtle deficits found in individuals with mTBI. Objectives: Based on the limited literature and clinical evidence describing traditional and current tests for measuring cognitive-communication deficits (CCD) of TBI, the strengths and weaknesses of the instruments are discussed relative to their use with mTBI. It is necessary to understand the nature and severity of CCD associated with mTBI for treatment planning and goal setting. Yet, the complexity of mTBI sustained in combat, which often co-occurs with PTSD and other psychological health and physiological issues, creates a clinical challenge for speech-language pathologists worldwide. The purpose of the paper is to explore methods for substantiating the nature and severity of CCD described by service members returning from combat. Methods: To better understand the nature of the functional cognitive-communication deficits described by service members returning from combat, a patient questionnaire and a test protocol were designed and administered to over 200 patients. Preliminary impressions are described addressing the nature of the deficits and the challenges faced in differentiating the etiologies of the CCD. Conclusions: Speech-language pathologists are challenged with evaluating, diagnosing, and treating the cognitive-communication deficits of mTBI resulting from combat-related injuries. Assessments that are sensitive to the functional deficits of mTBI are recommended. An interdisciplinary rehabilitation model is essential for differentially diagnosing the consequences of mTBI, PTSD, and other psychological and physical health concerns.

Composite Scale

The aim of this study was to examine the effect of posttraumatic stress disorder (PTSD) on (a) neuropsychological test performance and (b) self-reported emotional complaints within individuals suffering from postconcussional disorder (PCD) after a mild traumatic brain injury (MTBI). A two-group comparative research design was employed. Two MTBI samples with and without PTSD were assessed with a neuropsychological test battery and the Ruff Neurobehavioral Inventory (RNBI). On the neurocognitive test performances no significant between group differences were found, but the MTBI group with PTSD endorsed a significantly greater number of emotional complaints, especially in the RNBI subscales of anxiety and depression. The patients with PTSD also endorsed a significantly greater number of premorbid sequelae in the RNBI emotional composite scale as well as the RNBI premorbid subscales of pain, anxiety and abuse. In sum, PTSD has a negative impact on emotional but not cognitive functioning within individuals suffering from PCD after a mild TBI.
