Also, sometimes you can find a nurse who is more helpful than others and will provide you with some answeres you are seeking. They should have one.
Social workers can be a good advocate for the family or the patient.
I'm glad you called the doctor, please give updates as you can. It's important to have some support while goingt through difficult times. Maybe there is a local alzheimers support group you could contact. They can also be helpful to you. Thinking of you.
