In this paper, posttraumatic stress disorder (PTSD) will be written, which is a mental disorder and may occur in people who have experienced a very potent and life-threatening event. The traumatic event for every man is sudden, unexpected, embarrassing, and in such events the person is never ready. Every hour, someone becomes a victim of violence, a victim of a psychological trauma, either directly or as a witness. Consequences such as sexual and / or psychological abuse, participation in war operations, murders, heavy traffic accidents, natural disasters, sudden deaths of close relatives can be expressed immediately or developed into posttraumatic stress disorder. If he is a victim, he certainly wants to know what exactly happened to be able to take healing, recovery and return to normal life circumstances. Traumatic experience leaves a lasting mental, emotional, behavioral and physical consequence that the traumatized person wears on a daily basis. The quality of life and health is impaired. The person is no longer the same as before or before the trauma. It best recognizes and finds his family suffering the most. Psycho-radiotherapy is distanced and alienated from its family, can not function normally in a working and family environment, and what is characteristic not only of a person suffering from illness but also of members of his family is a feeling of helplessness that occurs. Family members do not know how and how to help. There is a need to react in time and seek professional help. Successful treatment is very important for good communication that needs to be established with the patient and that his family is involved with the patient as well, because it should be the greatest support and support, and this can greatly affect the course and outcome of the treatment. The first contact of the patient and his family with the doctor is through a medical interview, and by the arrival of the patient in the institution and the search for professional help, the health care service begins to be provided on an individual level for each patient in a holistic approach involving the entire health care team employees. Social awareness of human rights, violence and disasters has increased over the last 20 years, which has contributed to wars and natural disasters, which has led to the development of psychotraumatology. In Croatia, the area of psychotraumatology began to develop more intensively at the beginning of the 90s of the last century or during the Homeland War.
