PTSD Treatment Protocol Using Memory Reconsolidation Blockade
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current behavioral interventions for PTSD, such as trauma-focused cognitive behavioral therapies, are inadequate in providing long-lasting symptom reduction and often lead to retraumatization, with extinction-based methods experiencing spontaneous recovery and contextual renewal issues.
Innovation Solution
The Reconsolidation of Traumatic Memories (RTM) protocol, a brief clinician-guided intervention that utilizes the neurological mechanism of memory reconsolidation blockade, involves a controlled reminder of traumatic memories, interruption, and introduction of new information to transform the affective response, allowing for memory updating without retraumatization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If extinction-based exposure methods are used to treat PTSD, then symptom reduction is achieved, but spontaneous recovery and contextual renewal cause symptoms to return over time
Solution Approach 1:
The patent changes the fundamental mechanism parameter from extinction learning to reconsolidation blockade. By administering a beta-blocker (propranolol) during memory reactivation, the treatment modifies the physiological state during memory processing, preventing the reconsolidation of traumatic memories and producing durable symptom reduction that resists spontaneous recovery and contextual renewal.
2Reliability
If trauma-focused cognitive behavioral therapy is administered, then symptom reduction occurs, but treatment requires multiple sessions and follow-up care
Solution Approach 1:
The patent performs preliminary action by administering the beta-blocker medication before and during a single brief exposure session. This pre-treatment with propranolol prepares the patient's physiological state to block reconsolidation, allowing the entire treatment process to be completed in one session rather than requiring multiple weeks of therapy and follow-up appointments.
3Reliability
If exposure-based treatments are used, then traumatic memories are processed, but patients risk retraumatization
Solution Approach 1:
The patent introduces an intermediary substance (beta-blocker propranolol) that mediates between the traumatic memory reactivation and the patient's emotional response system. The medication blocks the physiological consolidation of emotional arousal during memory processing, allowing safe exposure without the full emotional impact that could cause retraumatization.

AI summary
A method or system by which a clinician can effectively treat the intrusive symptoms of PTSD in fewer than five sessions. The method depends upon a brief elicitation of the trauma memory that makes the memory susceptible to modification. This is followed by the introduction of new or novel information about the remembered event. Because of the labialization induced by the brief exposure, the new information is incorporated into the structure of the memory and the association between the memory and the traumatic feelings are severed. When this is successfully completed, the client is asked to relate the trauma narrative as the clinician assesses it for autonomic responsivity, fluidity and level of detail. If the client shows no discomfort the clinician invites the client to create a new script that eliminates the experience of the trauma, to relive that version in imago, and then to practice the new scenario in the first person in imago.
