Your situation is really tough I know how you feel except my mother was a lot older. All I can say is try to take it one day at a time and always give your Mom the dignity she deserves you also need to do things for yourself to keep your own sanity. Instead of making your Mom come into your world go into hers and if she says something different or unusual just play along because your Mom is different now but deep down I know she will somehow still sense who you are.

There are many ways to get a better understanding of what stage of the disease your mom is in, this site and others can help you with that.
Your mom is losing the present but she will retain more of the past still so spend more time with her looking at photo albums and talking about things you did as a family. The trips you may have taken, vacations and stuff like that.
Also ask her about her childhood and friends, you might also want to write a small book about your mother to share with your own children some day and now may be the last chance you have to get answers from her.
Ask about what it was like for her growing up, and meeting your dad and what her dreams had been. So much of that will still be fresh but even some may be starting to become confused.
This is so sad, my husband is 55 and he still remembers people he sees regularly but it's how to do things he is forgetting so rapidly, although he has forgotten all but two of our grandchildren because he doesn't see them and they were born after he developed AD so they don't really exist to him.
