Résumé : |
Objective To determine if elevated rapid-response impulsivity after blast exposure (as a putative marker of ventral prefrontal cortex [vPFC] damage) is predictive of future elevated affective symptomatology in blast-exposed service members. Design Longitudinal design with neurocognitive testing at initial assessment and 1-year follow-up assessment of psychiatric symptomatology by telephone interview. Setting Veterans Administration medical centers and postdeployment assessment centers at military bases. Participants Blast-exposed U.S. military personnel (N=84) ages 19 to 39 years old. Interventions Not applicable. Main Outcome Measures Center for Epidemiological Studies-Depression Scale (CES-D) scores, Posttraumatic Stress Disorder Checklist Version 5 (PCL-5) scores, and Alcohol Use Disorders Identification Test-C (AUDIT-C) scores at the 12-month follow-up telephone interview. Results After controlling for age and affective symptom scores reported at the initial assessment, commission errors on the Continuous Performance Test-II of the initial assessment were predictive of higher symptom scores on the CES-D and PCL-5 at follow-up, but were not predictive of AUDIT-C scores. Conclusions 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. |
