Al writes "Technology Review has an article about a common drug that seems to 'delete' painful memories related to a fearful experience. Experiments carried out by neuro-scientists at Emory University show that propranolol, a drug commonly used to treat high blood pressure, can suppress the emotional part of a fearful memory. The results, published in Nature Neuroscience, suggest a new way to treat anxiety disorders. In recent years, scientists have discovered that the simple act of remembering a past experience requires that the memory be consolidated once again. And both animal research and some human studies have shown that during re consolidation, long-term memories — once thought to be fairly stable — can be more easily meddled with."

Re:PropranoLOL (Score:5, Informative)
In the brain, a part of the brainstem known as the locus ceruleus is the site of norepinephrine synthesis, and it is activated by stress to send norepinephrine to the amygdalae, the brain's "emotional memory association" centers. It is in the amygdalae that memories are associated with emotions, with the ultimate result being that it is easier to form long term memories of experiences that associated with strong emotions. In blocking norepinephrine transmission to the amygdala, beta-blockers most likely are acting to uncouple the connection between a stressor and its associated memory, such that the brain no longer considers it important enough to keep in long term memory.

You know one does learn to avoid making many mistakes in life--I really cant fly, fire is pretty but it does hurt--by pain.
Besides just the idea of tampering with memory being a *bad* thing, the notion of fooling with one of the fundamental ways we learn strikes me as a really bad idea.

You speak as if our brain's software is without bugs. If you had seen the suffering and disablement that intense, often unreasonable, emotional pain can inflict on some people even years after the traumatic event, perhaps you would be less dismissive of an attempt to patch this particular bug.
Expose X people to a horrific event and a high percentage of them will show the ability to get over it. There is that outlying group, however, who (despite honest effort and therapy) seem to have an overactive emotional memory system which prevents them from ever coming to terms with what happened.

Wrong. No one just "get[s] over it." Every individual, based on their prior experiences will take a given situation and either adapt to it to the best of their abilities, perhaps by adding it to their experience or by "moving on" and ignoring it even though the effect is still with them at a subconscious level. And the really poorly off people break; they have something happen to them so traumatic that it shatters their emotions. While they are the most obvious "victims" of an event, if they can't find help

As I previously said, there is a group of people who, despite honest effort and therapy, do not recover from traumatic events. There is no support for a quick fix anywhere in my earlier comments. Stop attempting to straw-man this.
Bullshit. There are clearly innate and instinctual functions of our brain our higher processes wish they could override. We have an onion of a brain with layer upon layer of functionality, but also layer upon layer of cruft.
Flinching when you know the person isn't going to hit you. Accelerated heartbeat when you know it is only a movie. Goosebumps when you know you have no hair to fluff. Even the annoying sensation of cold when you know you are able to maintain core temperature. All of these are examples of where, despite conscious will, our base programming still rules.
You're assuming these people can learn. I'm arguing there is a class of case where normal brain function has been so disrupted by an overactive response to an emotional event that learning from the event is impossible. Despite your insistent wish to believe that isn't so.
Who says this is a one-size-fits-all solution? Not I. It appears to me that there is either a reading comprehension problem or a desire to straw-man again.
A non-functional personality can solve no problems. Either we do what we can to restore advanced functionality (and maybe this will prove an effective tool to do so) or we accept the person as a loss. Many really are just that far gone.

You're right, to an extent. Living without pain is very hard--some individuals born without the ability have hellish lives as a result. But sometimes, pain teaches us lessons that aren't so good, like "I should never touch anyone for the rest of my life," because touching is so strongly associated with pain. How people with this sort of thing varies from one individual to the next, but for someone with a deeply ingrained irrational fear based on some painful experience, maybe removing the memory could be a good thing.
Another way of looking at it is this: if you are raped, and the idea of sex is permanently distorted in your mind by the memory, then this memory is a punishment for something that isn't your fault, haunting you and messing up your life to this day. Wouldn't it be a good thing to allow the *option* of removing this weight from one's shoulders?

Now suppose that you and your family were kidnapped from your home at gun point, and you had to watch while unspeakable things were done to them and to you.
One thing you would 'learn' (and have a terrifying anxiety attack in response to) is that sitting around in your own home with your family is an unsafe thing to be doing, because something really bad happened one day when you were doing that. That response would be completely useless and would make your life an absolute misery.
That's the sort of thing this drug could be useful in 'editing out'. 'editing out' the sort of 'that hurt me last time I did that so I won't do it again' memories is a stupid idea and I don't know why anyone would bring it up.

The first thing I thought of when I first heard about the research on trauma-amnesia, despite all the articles talking about treating post traumatic stress, was "oh great, they'll be able to torture people and make them forget that it happened".

Lot of patients who I've dealt with who took this drug suffered from impotence and had to be changed to alternative medication - wonder if in fact all that happened is that they forgot what do with it :)

The article linked above also goes on to say:
"Kindt's team has already tested whether the propranolol effect lasts longer than three days--a key requirement for therapeutic use--but she declined to give the results because they have been submitted for publication."
So continuous treatment might be required? Side effects of prop. can be worse than the memories maybe?

If everything that you think you are (your memories) gets gradually shifted and rewritten from day to day, who are we? Never minding the fact that it appears our conscious existence ends when we die, it's almost as if we die a tiny bit every day. While I think I remember who I was 10, 20 years ago, if these memories are faulty and always being revised, perhaps I am that person no longer.
Some days, I look around and find it remarkable that I even exist. But, sadly, that appears to be a temporary state of being. Not only will I not exist in the future, it appears that I will not even be able to know I don't exist. And now, with these discoveries on memory, it appears that this gradual process of death happens even when we are still alive.

The drug in the study is a beta blocker. They are used heavily to treat high blood pressure, heart rhythm issues, and specific aspects of heart failure. The study indicates that they MAY be useful in helping to dampen the negative feelings associated with traumatic memories when combined with specifically designed therapy. There's no claim that they can actually cause a memory to be forgotten. It's not a potential lifestyle drug poised for widespread abuse. Most links I've seen to this article and others covering the study seem to suggest that simply popping one of these pills will make you forget an entire event at will. It's nowhere near that simple. If it were, I'd be a lot more laid-back than I actually am.

It seems far more likely, that this isn't actually "removing" anything from the brain in terms of bad thoughts, but instead is making the brain better able to cope with a bad experience by improving it's ability to reason it's way through it using common sense and logic.
Likewise, it could also be argued that people who can't normally focus on a simple task at will often end up going off on wild tangents at random instead, and will ultimately go insane trying to consciously resolve whatever scenario pops up in their mind at any given moment, only to shift the workload over to resolve a completely separate scenario brought on by attempting to resolve the previous one. Since this accomplish nothing but large amounts repetitive thinking on the same overall theme, while generating no useful information or solutions, it's not surprising that someone locked in such a state would be depressed and believe themselves to be "traumatized".
I suppose a beta-blocker might help a case like this, but it seems like this is simply restating the obvious to make whichever drug company did this study seem more "profitable" through sensationalism.
