Abstract
Comorbidity between TBI and C-PTSD is prevalent in this sample of police officers. Symptom endorsement is additive in those with mTBI history, this could lead to risk to employment, relationship breakdown, and further mental health problems. Routine occupational health checks should monitor both TBI and associated symptoms over time. If necessary, police officers with head or neck injuries should follow a graduated return-to-duty protocol, including a gradual increase in activity level and appropriate mental health intervention.
