The rhythm of today's life is accelerated and many people do not pay attention to their own psychological state. The consequence of this is the accumulation of traumatic or stressful developments in people. Stress or trauma is interpreted as an event beyond normal human experience. One form of illness that is associated with this is post-traumatic stress disorder (PTSD). PTSD engages the affected person as a whole by acting on all aspects of person's development, that is, biological, psychological and social aspects. Biological plan includes the changes in the functioning of the nervous system, disruption of neurotransmitters such as cortisol, epinephrine, endorphins etc., which leads to changes in the mood and functions of our organism. In the psychological sphere, the victim manifests numerous symptoms, such as dissociation, learned helplessness, intrusive dreams and memories, emotional dullness, solitariness, depression, etc. In the social environment, especially in the family, large dysfunction occur. The victim unfavourably affects his or her environment, which at the same time represents, or at least it should represent, the supporting structure in overcoming the difficulties. The victims of PTSD live a difficult life in which each new day represents the beginning of a struggle with oneself. What is considered ordinary and normal, like self-control, sense of security or desire to discover new things, respresents a remarkable effort and hard work to the victims of PTSD. Cognitive-behavioral therapy is an efficient form of psychotherapy whose effectiveness is proven by numerous clinical studies in the treatments of various psychological disorders. Therefore, the importance of conduction of treatments in order to enable the ill persons to deal with the situation in the easiest possible way is incontestable. With family support, understanding environment, participating in therapies and pastoral models which are provided by the Church and which can be provided with spiritual-psychological assistance, the victim of the disorder can work on himself or herself and thus expect positive steps in dealing with the illness.
