Effects of chronic alcohol abuse on neuropsychological test performance in individuals with traumatic brain injury Kreuch, T. J., Falcon, P., Gabel, B., & Hudson, D.

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.

Head Type

The neuropsychological test performance of subjects with traumatic brain injury (TBI) of the closed head type was investigated using a test battery consisting of traditional clinical instruments with expanded language measures. TBI subjects were specifically selected to include only those with a pattern of predominantly diffuse cerebral injury to allow conclusions regarding language performance in the absence of focal aphasia-producing lesions. Factor analysis of the test scores resulted in the extraction of three interpretable factors associated with performance on this battery: perceptual, general language, and mental efficiency. The results were compared to those obtained in previous factor-analytic studies of brain-damaged subjects, revealing patterns for the language/verbal subtests that diverged from those observed formerly. Two explanations are considered for these findings, the first interpretation centering on the notion of select impairments to specific cognitive processes and the second relating to impairments in the capacity to allocate resources effectively.
