Returning service members who have experienced traumatic events while deployed are often later diagnosed with PTSD (post traumatic stress disorder). People with PTSD are triggered by the event to experience a high-level of stress that won’t go away. It can cause anything from flashbacks to chronic anxiety.
Service members returning home must re-enter everyday life. Not all of them are successful in letting go of the stress of their deployment. According to experts, the trauma returns with symptoms of paranoia, heightened jitteriness, and a sense that people are out to get them.
