PTSD is defined in part by the presence of intrusive memories of the traumatic event. It might be supposed that amnesia would lessen the impact.
This was a small study designed to explore this self-evident truth.
In fact it was found that groups of people with extensive amnesia or, no traumatic memories of the index event, have higher levels of psychological distress than do those with traumatic memories.
Comment
Amnesia does not appear to protect against adverse psychological consequences of trauma.
But does protect against intrusive memories!
Diagnosable harm is required for compensation purposes. It would seem PTSD should not be cited in cases of amnesia, other diagnoses should apply.
