@lost55, this is such a good question. It might be a good idea to review her medications with the neurologist, including her medications not specifically for Alzheimer's dementia. As things change, so too may her medication needs or metabolism. I say this as a non-medical professional, but rather from experience with my aunt, who has Parkinson's. We also reviewed the time of day for taking various medications and reviewed the with/without food requirements, etc.

As you prepare for an appointment, I might suggest writing down her behaviourial patterns. That information might be helpful. If there is a long wait time until you can get to see her doctor, you might also have a chat with her pharmacist. Pharmacists are very knowledgeable, especially with drug interactions and reactions. They might be able to provide information about the behaviours you're experiencing and with that information help form questions to ask the neurologist.
