Mild traumatic brain injury and posttraumatic stress disorder: Investigation of visual attention in Operation Iraqi Freedom/Operation Enduring Freedom veterans

Kristen Barlow-Ogden, MA; William Poynter, PhD

Figure 4. Response accuracy for participants with mild traumatic brain injury who self-reported attentional complaints versus those who did not report such complaints.

Many veterans are returning from Iraq and Afghanistan with diagnoses of mild traumatic brain injury (mTBI) and posttraumatic stress disorder (PTSD). These veterans also report vision and attention problems. This study objectively measured the visual attention of veterans with mTBI and PTSD by using a computerized behavioral task that selectively showed stimuli to the subjects– left or right visual field. We observed slower and more variable response times in the veterans with both mTBI and PTSD. We also found that veterans with both mTBI and PTSD were slower to orient their attention to the left visual field, while veterans with PTSD only showed the opposite pattern (slower to orient attention to the right visual field).
