Military personnel exposed to trauma in war zones often experience post-traumatic stress reactions like nightmares and anxiety even after returning home. These stress reactions can negatively impact their families by causing emotional distance, irritability, and loss of interest in social activities. Treatment for PTSD focuses on reducing fear/anxiety, gaining control over reactions, making sense of trauma experiences, and improving functioning. Family support is important to recovery, and families should educate themselves, communicate with the veteran, and seek their own help if needed.
