Thought I'd post an update and more info on DDs condition, it's the strangest thing.
Her personality is 100% in tact, her sense of reason and logic are in tact and to talk to her you would never know anything is wrong except for the fact that she doesn't remember most of her adult life.
She knows that she has been with her husband for 11 yrs, she knows that she loves him and trusts him and she would not have married him and had children with him if she didn't. She just doesn't have 11 yrs worth of memories with him. She doesn't remember her wedding but remembered a ring that her H gave her on their first anniversary and when prompted was able to come up with the details of where they went and how romantic it was.
She remembers giving birth and the first few months after but nothing of her 2 yr old after that. She is amazed by how smart he is and that she actually taught him his numbers, shapes, colors, etc...
She remembers cousins but not their children, she remembers a dog I had that died but not the one I've had for 6 yrs.
She doesn't remember that she spins her own yarn, knits her own socks, quilts, bakes, makes her own soaps, detergents and deodorant.
I've heard stories of similar situations from a couple friends, one got his memory back after just a week, the other took almost a year.
SIL got referral and paperwork from ER yesterday and is waiting on call back from neurologist. We're hoping to get her in this week.
