Sometimes there is a reason for remembering horrifying things.

Before the crowd comes in and says, "oh, but if you erase memories, you are erasing part of yourself. You need to experience all of life, it's the pain that makes you a better person," etc. I'd just like to say Fark you. Try living with PTSD for many years and see how eager you are to keep living life to the fullest.

I've never met anyone who has had PTSD who disagrees with me on that, either. Wipe that shiat out, take it away. It damn near drove me to suicide.

Yeah, but before you have a vampire glamour you to forget your PTSD, make sure that you haven't hired an old Army buddy to kill you with a sniper round.

A new study from MIT reveals a gene that is critical to the process of memory extinction. Enhancing the activity of this gene, known as Tet1, might benefit people with posttraumatic stress disorder (PTSD) by making it easier to replace fearful memories with more positive associations, says Li-Huei Tsai, director of MIT's Picower Institute for Learning and Memory.

The scientists are planning an offensive on this particular gene?

There was a Radiolab episode about a couple guys who discovered how to erase specific memories from rats, and from the first published articles these guys were inundated with letters from people (with depression, trauma, abuse, PTSD, etc.) begging them to be the first human test subjects. It was heartbreaking, and I wholly understand and support the right of people to take control of their own memories, provided this treatment ever takes off.

I have PTSD. I don't want the memories erased; I just want them coded to the hard drive correctly so they aren't stored in the cache and so fresh all the time. It sucks walking around being constantly reminded about the shiat that's happened because "time" doesn't heal all wounds.

But to take the memories away? Fark. I'd lose a lot of my life as I can remember shiat from when I was 3. I may not like the amount of trauma I've gone through, but it's still my life.

Not much of a step from wiping out memories to treat PTSD to memory wiping criminals or political opponents is there? Should be fun.

Yup.

Though this isn't about memory wipe, it's about the normal fade with time. PTSD means that when the memory is triggered the emotional response is like it just happened. Imagine losing a loved one, then when you see things that remind you of them...years later...losing your shiat over it like they had just died.

It's disproportionate. And with PTSD it's not just a bad event, some people have biological predisposition towards it. Having some trauma over a bad event is normal it's how we learn to avoid things. No one is suggesting that we eliminate all pain from life, and all bad or unpleasant memories or something.

And to those who think they need the experience, go to the dentist next time you need a root canal and tell them no medication for you. You need the experience of your pain. Lemme know how that goes.

I wrote my thesis on PTSD so I'm getting a kick.... and so on.

The problem with PTSD isn't the memory itself. It's the wildly inappropriate additional connections that the memory forms as a result of a system that works pretty well until it gets flooded with excess adrenaline.

It's sensible for the brain to learn to be afraid of tigers if you've been attacked by a tiger. It's not sensible for PTSD to generalise that fear to the extent that a LOLCATS youtube video causes a debilitating flashback.

Yup. Reward system gone haywire. I *know* what's going on in my head, doesn't mean I have even a snowball's chance in hell of stopping it.

And then everyone looks at you like why can't you just get over it already.
