Simulated Driving Performance of Combat Veterans With Mild Tramatic Brain Injury and Posttraumatic Stress Disorder

This study determines the differences in driving errors between combat veterans with mild traumatic brain injury and posttraumatic stress disorder (PTSD) and a healthy control group through the use of a driving simulator. The investigation used 18 postdeployed combat veterans and 20 control participants. The combat veterans tended to be male, younger, more racially diverse, have less formal education, and have lower cognitive scores than the control participants. The combat veterans made more errors than the control group, such as overspeeding, and adjustment to stimuli, and signaling errors. These errors may lead to more crashes or injuries and there might be cause for driving interventions for combat veterans.
