Exposure to Trauma Impacts Ability to Crush Bad Memories

Individuals uncovered to trauma are much less in a position to suppress undesirable emotional recollections as a consequence of neural and behavioral disruptions of their mind which will contribute to the event of post-traumatic stress disorder (PTSD).

PTSD is characterized by intense reliving of the trauma that’s repetitive, intrusive and incapacitating. The intrusive nature of those hallmark signs means that the inability to suppress undesirable memories could also be a robust contributor to the behavioral manifestation of PTSD.

Earlier work has proven that wholesome people can actively suppress emotional memories whereas people with PTSD ceaselessly expertise undesirable memories of their traumatic experiences, even when making express efforts to keep away from them. Nonetheless, little is understood relating to the behavioral and neural results of reminiscence suppression amongst people with PTSD.

Utilizing useful magnetic resonance imaging, the researchers examined memory suppression in three teams: these with PTSD; those that skilled trauma without PTSD and controls with no trauma publicity or PTSD. They discovered trauma-exposed members (regardless of PTSD status) have been much less prone to efficiently suppress memory than non-trauma-exposed controls.

“Neuroimaging data revealed that trauma-exposed individuals showed reduced activation in the right middle frontal gyrus, a critical region for memory suppression, during a memory suppression task and were less likely to successfully suppress memory compared to non-trauma exposed individuals. These results suggest that trauma exposure is associated with neural and behavioral disruptions in memory suppression and point to the possibility that difficulty in active suppression of memories may be just one of several likely factors contributing to the development of PTSD,” said by lead author Danielle R. Sullivan, PhD, affiliated with Boston University School of Medicine and the National Center for PTSD, VA Boston Healthcare System.
