In this final paper, the topic of Posttraumatic Stress Disorder is addressed. Particular attention has been paid to the comorbid disorders that occur in the majority of patients with PTSD. This disorder has been identified as one of the most complex psychiatric disorders. Comorbid disorders that are associated with PTSD are depressive disorders, anxiety disorders, panic disorders, and the development of addiction to either alkaloch, psychoactive substances or marijuana and similar. In addition, patients with this disorder have a high rate of suicidality and personality change. In men, PTSD is most often caused by war events, while in women, PTSD occurs as a result of abuse, which is usually sexual. In order to effectively combat and treat PTSD, it is necessary to operate from multiple domains; medical, psychological, and sociological. Therefore, the patient must receive adequate medical care, psychological and psychiatric help, and must be trained to return to society, or to the community to which he or she belongs to using the methods of re-learning socialization. During the recovery process of the diseased person, the entire team of specialists treating the patient, and especially the nurse, who monitors the patient for the entire duration of treatment is of utmost importance. It is crucial to raise public awareness of the problems and disabilities encountered by PTSD patients in their daily lives, and to insist on the constant education and reintegration of individuals with this disorder into society.
