My mom too. Right at 2 years ago. We actually don't know for sure that she had Alzheimer's because she refused all medical care once her memory started to slip. She would say, "I know I'm losing my memory. I don't want to be doped-up. You can deal with it."

And, she forced me to deal with it even though she absolutely refused to do any end-of-life paperwork. It was horrible dealing with my mother and our system.
