Rather than a broken brain, a changed brain. If perceived as broken, the medium of delivery is poor. It is something/a fact that you have to accept/come to grips with in order to move on. To say I can know about it but you can't handle (the truth) it, so it's better you don't know, seems to me to be somewhat over controlling/hypocritical. Maybe it's about giving people time to digest it slowly. But never say some people should never be exposed to it. Delivery...
I do agree with you that the question of where to once you have understood to a reasonable level the brain research, etc etc as in: where to from there? Where are the concrete examples of the next steps to take in order to achieve a better quality of resilience, keeping in mind it's more bouncing back than mainstream resilience learning, given the brain changes etc!
Additionally, how to apply to individuals needs, as well as group and community, addressing these particular needs. Of course one size will not fit all.
It's a challenge! But more doable than is currently out there.
