The Accuracy of Traumatic Memories in Posttraumatic Stress Disorder: A Review

This review sought to investigate the accuracy of traumatic memories in persons with a diagnosis of posttraumatic stress disorder (PTSD). PubMed, PsycINFO, and Embase were searched for articles, and 11 studies were included. Three different methods of studying memory accuracy were identified in the included articles: coherence, change in recollection of trauma over time, and remembering details of trauma. Three studies found a deficiency in the accuracy of traumatic memory. Despite some inconsistencies, most of the studies concluded that the memory of trauma is as accurate in people with as in those without PTSD. The only recurring difference identified across studies was in recollection of trauma over time. The findings are of importance both clinically and for the legal system.
