Other treatments are currently being developed for PTSD. In our lab, we work on one. It's a little bit complicated, but essentially, it's trying to dampen the emotional tone of the traumatic memory to alleviate the symptoms. We've been working on it for about a decade.
What's really fun with it is that we get similar results to those from evidence-based treatments, right now, but we do it in half the time, at half the cost, and with students who can be trained right out...undergraduates do it because it's a very easy treatment to implement.
These types of things are coming up. It's still in the experimental phase, so it's not widely used right now, but these things are coming up too. Our hope is that, in the near future, it becomes something that's more mainstream and that more people can be trained and we can reach a lot more people.
