i just recently lost my grandma who was diagnosed with alzheimers two years ago. i moved in and took care of her literally as long as i could until she became too much to bear with 2 school age children and a toddler. so we had to seek out extra help. but as a caretaker teh best thing i can tell you is taht you are pretty much dealing with a toddler right now. so honestly the best thing to do is behave in the same way you would with a 3 year old. try to keep thigns as familar as you can adn try to stay as calm as you can. believe me if they see you upset it makes them more apt to argue and go on. good luck, i know firsthand its hard. i lost both my grandmothers to this disease but like i said i watched it firsthand destroy my granny who died in april. all the medicine in the world does not help. just be calm and keep life as familiar as you can. dont argue and really get ready to deal with a baby, cuz thats what it was like for me. but i would have done it a million times over and i miss her more every day.
