Memory 'erasing' and recovery from trauma?

IN the last week or so, I listened to an interview with a researcher in Ontario, I *think* at the University of Western Ontario, on CBC (Canadian Broadcasting Corporation). It was a case where I think I had heard about some of the theories behind the research at some point a few years back, and the story of it had intrigued me since then. The researcher was being interviewed on some recent work on the brain, and how memories of traumatic events can be manipulated in some way, perhaps even 'erasing' them. Research has indicated that there may be - if there isn't already - medical/neurological processes available to essentially erase a trauma-causing memory from the brain of a person suffering with Post-Traumatic Stress Disorder. The CBC interview host was aware of current discussion on this research, and its implications, pointing to a question of whether more damage would be done to a person's overall memory functions if such a procedure were implemented. What's more, the question must be raised about the inherent value of even the most horrific of memories. I have PTSD, stemming from childhood and an event as an adult, and I am not sure if I would opt to remove those memory/ events from my brain, if the procedure were there. Perhaps that is because my trauma and the ensuing depression, and anxiety, and repercussions on my ability to trust, and have relationships, have been the focus of considerable psychiatric and psychological help. I am also 'high-functioning', able to function well daily, and to aim for success, as well as to visualize successful outcomes and a future. For others, the possibility of erasing memory -or memories - might be the means to true health, to being able to function at all. There is no doubt at all that PTSD can sap life, can eat away at function, and that it 'traps' people, paralyzing them in a state of immobility (at all levels - physical, intellectual, cognitive, relational). The researcher in the interview pointed out that a person with PTSD isn't really remembering a memory, as much as they are actually RELIVING the event. Their brain and body goes 'back there', they ARE there. It is not the same as a fond or even no-emotion-involved remembering of some event which was not generally stressful, or traumatic. Reliving traumatic events is HORRIBLE. My brain, my eyes, my sight, are all really there - even though I am sitting in conversation with someone in a restaurant. Would I choose to have one of my traumatic 'relivings' removed? Would you? Must go for now ---- have a flu bug or something.
