My mother was diagnosed with sever dementia. She began taking aricept 4 days ago. Since then her behavior has changed. The first night she became tired, the second night she became very agitated and paranoid, the 2nd morning, I found her sitting at the edge of her bed, her hands clasped on her lap head down and telling me she was alone, that everyone had left her. She started crying saying she wanted to die. I assured her she was not alone that myself and her grandson was here with her. It seemed to take me talking to her for over an hour for her to snap out of it. The day went ok, but the periodically I would catch that faraway look in her eye and sadness. My father passed away 7 years ago and they had been married 60 years. I'm thinking pulling her off this medicine. I prefer her the way she was, Dr. Jekyll and Mr. Hyde personality that she has for the last 2 years. At the very least, there was no sadness, no tears and no wanting to just die. This behavior just hurts my heart. I would rather be frustrated by her behavior than this sadness.
