[Diagnostic criteria of posttraumatic stress disorder].

The authors consider historical and diagnostic aspects of the origin of the posttraumatic stress disorder diagnosis (PTSD). Different criteria of PTSD presented in diagnostic systems ICD-10 and DSM (from DSM-III to DSM-IV-TR) are analyzed. Attention is drawn to diagnostic definition of "acute stress disorder" (ASD) and its place in the dynamics of PTSD: ASD, acute PTSD, chronic PTSD. The authors claim the existence of PTSD as a distinct diagnostic entity and note that there are substantial differences in the clinical interpretation of distinct psychopathological phenomena involved in the PTSD structure by different authors.
