My mother seems to be mid stage 6 Alzheimer's. She has really taken a turn for the worse in the past few days. Angry outbursts, unfamiliar in her own home, yet she knows where everything is. Asking when she can go home. It seems she has regressed to her late teens. We (children and grandchildren) are familiar to her but we are not her family. I am the oldest and she asks how I can be her child if I am older than her. Also signs of Sundown Syndrome. She is not on any Alzheimer's medications. Tried Aracept but it made her very sick. She has taken Risperadone on occasion, but will start on it daily.
