I understand why injury can be used, and how stress does actually affect the brain functioning, apparently with a threshold point that triggers PTSD. If you look at the term, Post-Traumatic Stress Disorder, technically it’s a stress disorder consecutive to a trauma, that is namely, a form of injury. Replacing disorder with injury in this nomenclature doesn’t make much sense, it’s redundant and technically it would say it’s a stress injury consecutive to an injury. From a strict grammar point of view, I don’t get what a "stress injury" would mean. For me it sounds inelegant and not explanatory of what actually is—a disorder with typical sensations of fear and a variety of behavioural responses. If it is to revise the nomenclature to make it sound less discriminatory… then perhaps revising it entirely and not just replacing one word.
It’s a pain in the ass that "disorders" have such a bad advertising, going with famous bipolar disorder and the terrible personality disorders. But it is what it is, something embedded in you but treatable.
In continental Europe all the imagery of combat PTSD is much less prevalent than in the US, there isn’t much of that image of the veteran gone cuckoo. Actually there is, but it’s practically deemed nonexistent because there isn’t a critical mass of PTSD’d veterans. It’s as if it were an American thing. There is a lot of discussion about family trauma but clearly more on a psychoanalytic/language point of view and the neurological level is vastly unknown in general conversation but also by a number of counselors. And in psychiatry, it’s very quickly diagnosed either with depression or a personality disorder. I’ve almost got stamped with BPD where I clearly didn’t meet enough criteria. There is generally more a tendency to diagnose you with depression + there-is-something-wrong-with-you, and PTSD feels far more liberating than the blank I had before.
In French they chose to translate disorder with "trouble", which sounds much less scary. It sounds more like something of Post Traumatic Stress Mess, but it’s also super vague. It’s quite a problem that the names are translated from the DSM, as it’s difficult to find something that matches the original meaning, while the original wording also was difficult to find.
Besides that I think the difficult part isn’t so much to deal with the discrimination of the term PTSD, but just basic comprehension. And I guess there are so many flavours and a spectrum of severity in PTSD that it’s difficult to bring a one-size-fits-all explanation. It’s a conversation that is long, complicated, vaguely boring and evidently upsetting given it’s about trauma.
I find that the discrimination lies much more in the reasons of the trauma than in the disorder itself. Explain that you’ve gone cuckoo because you had a horrible car accident that killed half of your family, expect some compassion. Explain that you’ve been abused and most likely coped with it in some collaborative way with the abuser before you could leave and you’ve got PTSD in the whole process, then it triggers fear and discomfort because no one wants to see how incredibly prevalent abuse and violence is, and it’s easy to stamp you as "crazy" or broken and ignore the entire thing. That for me is the core of the social conversation, and then seeing the consequences on people’s mental health.
Another discriminatory part is simply the social consequence of being dysfunctioning in a level or another. Then you are perceived as deficient, or eventually dangerous. Western society has a great intolerance for any kind of dysfunction or basically anything that questions its core beliefs. Rebranding the disorder I think will have little to no effect on this. It’s displacing the problem. As soon as it would be understood as being that "thing," it will be just the same. But I completely understand that some might feel more comfortable with a different term.
