The document discusses the effects that post-traumatic stress disorder (PTSD) can have on military families. It notes that 15-20% of soldiers deployed to Iraq and Afghanistan exhibit symptoms of PTSD or depression. Having multiple deployments increases the risk. PTSD can cause nightmares, flashbacks, addiction, isolation, and mood changes in the afflicted person. These changes then impact the family by changing the family dynamic and affecting relationships between partners and parents and children. Treatment may involve therapy for both the individual and the family unit to help all members cope with the disorder.
