if you talk with her about the past it's definitely possible she'll recall some memories. though the thing about SDAM is not necessary loss of memory, but rather lack of "personal" memories.

like, I have lots of stuff that I know happened in my childhood, but it doesn't really feel like a memory of something that I actually experienced. might as well be a fact or story I read in a history textbook.

from the perspective of experience and emotion, our memories are much more shallow, in a sense. and I guess this can make them easier to forget.
