Factors Influencing Cognitive Functioning Following Mild Traumatic Brain Injury in OIF/OEF Burn Patients
Abstract
To examine the relationship between mild traumatic brain injury (mTBI), psychiatric conditions, pain medications, and injury severity on cognitive functioning in service members admitted to a burn unit. We hypothesize that psychiatric co-morbidity and pain medications will have a stronger relationship with cognitive dysfunction than mTBI diagnosis in this population. Method : Retrospective review of clinical evaluations ( n = 194) completed between September 2005 October 2007 on service members with burn injuries secondary to explosive munitions. Evaluations were completed during the acute stage of recovery (mean = 7.87 weeks). mTBI diagnosis ( n = 50) was made through a clinical interview using ACRM criteria [1]. Exclusion criteria included duration of posttraumatic amnesia greater than 24 hours ( n = 10); and inability to complete neurocognitive measures due to severe bimanual burns and/or amputations ( n = 17). Cognitive functioning was evaluated using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Results : Subjects who sustained mTBI demonstrated significantly greater difficulty on the RBANS visuospatial and attention/processing speed indices. A hierarchical linear regression, using mTBI diagnosis, psychiatric diagnosis, time since injury, presence of pain medications, and measures of trauma severity as predictive factors, found that mTBI diagnosis had a significant, but small unique effect on cognitive functioning. Contrary to our hypothesis, psychiatric co-morbidity was not shown to have a significant effect on this population of acutely injured service members.
