My grandmother may have had a stroke :(

I got a call from my mother this morning and evidently my grandmother wasn't feeling well friday night. She went to bed and slept for 24 hrs. When she woke up she said she still didn't feel well and was really shaky. My grandmother said she thinks she may have had a stroke but didn't go to the doctor!!! My uncle lives with her, my aunt lives very close by...she has plenty of people that could have taken her (and SHOULD have) taken her to the Dr's this weekend. My mom didn't know about this until earlier today and is going to call them again tomorrow to try and convince them to go to the doctor. She lives in another state so nothing I can really do. My grandmother is 90 and is still very independent...but she does have some health issues and is losing her eyesight very rapidly now. I called her earlier and she called back and sounded ok on the message. A little loopy though, I assumed she had gone to the Dr's and was on drugs! So thats concerning me a lot!
