Well, my story is a sad one. I cared for my mother prior to her dementia. And have seen it progress quite quickly. One of the things I am struggling with is her lack of sleep at night. She tends to speak as if she was having a conversation with somebody and at times doesn't fall asleep until 4 in the morning. Also, she speaks a lot about people who have already passed. Can anybody relate to these things and any advice? My mother is 89 and I care for her 24-7.
