RECONsolidation of Traumatic Memories to ResOLve Post Traumatic Stress Disorder (RECONTROLPTSD)

"RTM is a trauma-focused, but not cognitive behavioral, therapy: it involves brief exposure to the trauma memory, but does rely on conscious responses to correct the symptoms of PTSD. RTM was first used to treat phobias in the 1970s, and has more recently been refined to focus on reconsolidation to update long-term memories, reconfiguring the salience structure of the original memory, and incorporating those changes into the overall memory structure. Reconsolidation is a neural mechanism for updating long-term memory, inserting new information that contradicts an essential element of the memory, which makes it possible to change the emotional tone and salience of the memory. It is hypothesized that RTM can thereby achieve quicker, greater, and more durable responses than with traditional exposure therapies."

PE is a trauma-focused cognitive behavioral therapy (TFCBT) that depends on exposure to the feared stimulus as a central effector of change, utilizing extinction, which theorizes that if a trigger that previously elicited a fear response is presented enough times without reinforcement, the response fades. Previous researchers have shown that extinction involves the creation of a new blocking memory which prevents expression of the original fear memory. While PE has more evidence to support its efficacy in PTSD than other approaches, and a majority achieve a clinical response (e.g., decrease in CAPS score of 10 or more), many do not achieve complete remission of symptoms, and the blocking memory may be fragile, so subsequent triggers may result in relapse.
