DSM 5 is a welcome refinement of the definition of Post Traumatic Stress Disorder (PTSD).
It reflects an expansion in the understanding of the condition. It is simply and explicitly worded.
The recognition of professional exposure to the condition is in my view long overdue.
The separation of how children aged 6 and under are qualitatively different in their responses to
trauma than more mature individuals is again an important addition.
The definition also expands on risk-taking behaviour, however my only criticism is like DSM IV the
new criteria fail to quantify or monitor change in the level of distress experienced by individuals.
