Abstract:
One of prototypes of PTSD is a fright neurosis conceptualized by Kraepelin and is on the line of traditional psychogenic reaction category defined by Sommers in so far as the re-experience symptoms reflects the content of a traumatic experience. Other key components of PTSD, such as avoidance of traumatic memory and hyperarousal, overlap respectively with dissociative disorders and the somatoform autonomic dysfunction (ICD-10), which may consist, together with comorbid mood and anxiety disorders of PTSD, a spectrum of posttraumatic mental disorders. The DSM-5 draft of PTSD restricts the category in terms of the event and re-experience criterion, put an emphasis upon dissociation and enlarges numbing symptom in that it is re-categorized as a cognitive and affective alterations to be separated from avoidance symptom. This change partly reflects insight into the nature of the disorder brought by CBT-based clinical experience.
