Alright, so I know I said yesterday I would keep everyone updated, so here's the scoop:
I just got off the phone with Mom, and they're for sure keeping her in the hospital for at least one more day. They know now that she had three mini-strokes. These caused her to loose some abilities of speech and reading. The speech therapist however said she should be able to regain all abilities of speech and reading over time. They're doing some tests today to make sure the strokes didn't do any damage to her heart.
Like I said, she lost the abilty to say some things, and she's struggling with reading, but she can still understand everything people say to her. So I read some verses to her while I was on the phone with her, and she really enjoyed that.
Thank you everyone for the prayers! I'll be sure to keep you all updated with further developments.
