The injuries of war change the lives of service members, families and children. Invisible injuries such as post traumatic stress disorder (PTSD) or mild traumatic brain injury (mTBI) can be especially difficult for families because they often result in significant changes in personality and behavior without changes in one’s appearance. A service member with PTSD or mTBI may have mood swings, or certain environments may trigger responses that do not seem appropriate to the situation. These kinds of events can be especially troubling for children, and embarrassing for the family.
