I'm an Alzheimer's patient myself and did a lot of volunteer work with the Alzheimer's association when I was first diagnosed (Sept 2003). I'm so glad I did the volunteer work because I learned so much. From what I gather, Alzheimer's patients often will become confused -- and it will become worse as time goes on.
PLEASE MAKE SURE THE DOCTOR IS AWARE OF THESE CHANGES. HE/SHE MAY BE ABLE TO MAKE A CHANGE IN THE MEDICATION TO IMPROVE HER QUALITY OF LIFE!
Also, in case you're not aware of it, Alzheimer's patients will often wander away from home -- and there are devices an Alzie patient can wear 24/7 to assist in locating them. If the facility you're using doesn't provide such a service, you need to get a "MedicAlert/Alzheimer's Association Safe Return" device (see http://www.alz.org/safetycenter/we_can_help_safety_medicalert_safereturn.asp).
Most importantly, learn as much as you can from the Internet "“ especially the Alzheimer's Association (www.alz.org). There's also a number you can call anytime day or night for assistance.
My best wishes to you, your family, and your Alzheimer's patient!
