abstract="OBJECTIVE: To assess whether increased incidence of post-traumatic stress disorder and depressive symptomatology in veterans with combat-related traumatic brain injury might help account for neurocognitive impairment relative to civilians with traumatic brain injury. PARTICIPANTS: Neuropsychological assessment data of 53 Operation Enduring Freedom/Operation Iraqi Freedom veterans and 48 civilians with positive history of traumatic brain injury were analyzed to assess differences with respect to cognitive performance.
DESIGN: Retrospective analysis of data including neurocognitive test performance and self-reported symptoms of post-traumatic stress disorder and depression.
RESULTS: Results showed worse neurocognitive performance (i.e. RBANS Total Index score) in the veteran sample relative to the civilian sample [F(1,99) = 3.92, p =.05, ƞ2 =.04], particularly on tasks measuring attentional capabilities [F(1,99) = 9.18, p =.003, ƞ2 =.09]. Additional analyses found that after controlling for post-traumatic stress disorder symptomatology, differences were no longer significant. Broad correlations between measures also showcased attenuated relationships after controlling for both post-traumatic stress disorder and depressive symptomatology using partial correlations Conclusion: Findings suggest that the presence of post-traumatic stress disorder and depressive symptomatology negatively impacts cognitive performance across neuropsychological assessment above and beyond deficits related to traumatic brain injury.
