Scary,
Big hugs, Alz is a very horrible disease. My mom is in a nursing home in the lock down unit with an ankle bracelet because she is an escape artist. I tried very hard to care for her even though she never showed any true love for me. It took the County Sheriff and Social Services on their last trip to my home to convince me that her violence toward me was never going to change and one of these calls to 911 which she always made to tell them I was the Mafia holding her hostage after every attempt to beat me up. The last time she tried to beat me up right in front of two County Sheriff Officers. He also told me that they had been watching my house for weeks ever since she slugged an EMT worker.
It is very true they are not in their right minds. Just remember the good times with your mom.
