Mild Traumatic Brain Injury in U.S. Military Veterans: Results from the National Health and Resilience in Veterans Study.

Overall, 3.0% of veterans had mTBI+PCS, suggesting that while mTBI may be prevalent in this population, the majority will likely recover without developing chronic symptoms. Those with mTBI+PCS are at significant risk for comorbid psychiatric diagnoses and poorer psychosocial functioning relative to those without mTBI+PCS, and early targeted identification may assist in prevention of disability and recovery.
