I have heard that the older you get, the LESS you sleep, not more. My mother will go to sleep around 7 or 8 pm and sleep for about 12-13 hours. She will get up and wander around a bit and then climb back in bed. Not sure if she would keep on sleeping as I usually will go in her room, open her windows and start talking to her so she gets up. Is this normal? I think she may just be bored. She just basically spends her time reading, watching TV, and says that is all she wants to do. Sometimes I can get her to take a walk or visit the neighbor. But I guess my question is should I be worried that she sleeps so many hours? She otherwise seems healthy other than the (mild) dementia.
