The purpose of this review is to provide an historical understanding of post- traumatic stress disorder. The concept of trauma is changing drastically in every publication or revision of Diagnostic and Statistical Manual of Mental Disorders. The underlying dimensions of trauma are also under constant consideration. Thus, the paper would provide some historical background of trauma nomenclature. This will enable the researcher to think of future diagnosis and differential diagnosis of traumatic syndromes. Posttraumatic stress disorder has been out there as back as human history. However, the recognition of traumatic symptoms on people’s lives and mental health has been recently recognized. Even though non-governmental organizations and civic society drew attention of this issue for a long time, the legal and administrative bodies were reluctant to take action and recognize the effects of traumatic experiences on people’s life.
Key words: Post traumatic stress disorder, statistical manual, mental disorders, nomenclature, post-traumatic stress disorder (PTSD), historical evaluation of PTSD.
