The Separate and Cumulative Effects of TBI and PTSD on Cognitive Function and Emotional Control
Abstract
In an emotional Stroop task, combat-related words were more distracting for Veterans with PTSD than for those without. We believe the test is a suitable measure of emotional reactivity and attentional bias that can be obtained before and after behavioral and pharmacological therapies. In addition, the patients showed a substantial deficit in motor response inhibition. Greater PTSD and depressive symptoms were both associated with worse performance on the motor task. The co-occurrence of mTBI and PTSD did not worsen the emotional and cognitive control difficulties associated with PTSD alone. Increased levels of impulsivity and a decreased ability to filter out distracting and emotionally intrusive information can negatively impact social and occupational functioning. new EEG findings revealed that Veterans with mTBI/PTSD showed deficits in error monitoring processes that are implemented by the medical prefrontal cortex. In the future support vector machine learning algorithms will be applied to sets of multiple EEG measures. This may assist in the classification of patient groups vs. controls.
