Hi. I'm sorry if this has been asked hundreds of times before but is it normal for people with advanced Alzheimer's to sleep a lot? My mom sleeps all through the night for a good 9-10 hours, she snoozes on and off all day and a few times the last couple of weeks she doesn't want to get up in the morning. When i spoke to my dad about 10:30-10:45 Saturday morning she was still fast asleep. She did have a urine test a week ago but that came back clear. A lot of things i've read say its common to sleep less but i haven't really seen anything about sleeping more. Is this just part of the progression of the disease or should we speak to her doctor? Thank you in advance.
