Rapid-Response Impulsivity Predicts Depression and Posttraumatic Stress Disorder Symptomatology at 1-Year Follow-Up in Blast-Exposed Service Members

Elevated rapid-response impulsivity, as a behavioral marker of reduced top-down frontocortical control, is a risk factor for elevated mood and posttraumatic stress disorder symptoms over time in blast-exposed individuals. Future longitudinal studies with predeployment neurobehavioral testing could enable attribution of this relation to blast-related vPFC damage.
