Due to my lack of knowledge in amnesia I googled it. Turns out, Retrograde amnesia loses memories after an accident while Anterograde amnesia is the inability to create new memories. A person with retrograde amnesia can still make new memories but has lost memories of who they were before that. Though, the more recent memories are lost so distant memories are kept. What your character has by what I've read in the posts and character sheet seems to be Anterograde amnesia which makes life quite a bit harder really since we have no idea how to treat it with medicine and I'm not entirely sure if there is any magic known to man which could heal such a thing.
Ah, excuse me. The terms must have gotten mixed up in my head in the past few years. Sorry about that, you're exactly right :D
The only known 'cure' is hoping the injury wasn't too severe and that the brain will heal itself, from what I remember.
Anyhow, she tries to cope via heavy journal usage and secondhand information, and it's been long enough that she simply stopped caring. Of course, the journal only helps so much...
Magic, to me, requires intimate knowledge of some aspect of what you're trying to modify, so yeah, "normal" medical magics, as they exist in her homeland, won't likely be able to heal it for a few centuries - and I don't think she'd be willing to accept the treatment in the first place.
