This section explores co-occurring issues that could potentially have an effect on trauma responses and behavior in general. The prevalence of Traumatic Brain Injury (TBI) and Post-Traumatic Stress Disorder (PTSD) among veterans returning from the wars in Iraq and Afghanistan is presented along with information related to Military Sexual Trauma (MST). Best practices for distinguishing TBI, Post-Traumatic Stress Disorder (PTSD), and Domestic Violence (DV) are identified. Additionally, how to design effective interventions to best address these challenging issues when they co-occur are highlighted. A glossary of the most used military-related terms is included throughout this collection for clarification. Lastly, we offer information about existing partnerships between anti-violence organizations, TBI service providers and the military as well as other similar successful collaboration models.
