Everyone and every situation is different, so I couldn't give you an accurate answer to that. I do know that it is an extremely wide umbrella. Dissociation is actually something Everyone experiences at some point. If it doesn't happen alot, there's a better chance of being unaffected. Like highway hypnosis. It might freak you out after it happens but you generally shake it off and be more aware. Whereas a person who experiences repeated trauma or maybe even a more..life threatening type of trauma will have a greater likelihood of being affected and needing treatment. And depending on the person and how, if, they get treatment what treatments they do, what their support circles look like, what, if any, resources do they have access to. So really, that's where the variables really come into play but on spectrum, Dissociation can be resolved. On the other spectrum, depending on circumstance worst case it cant and its more about management than trying to cure. I assume there's way better info though than I can give you here. This is bare bones.
