My loved one is 90 years old. She is a widow and lives alone. She has dementia and diabetes. She is medically overweight, bordering on obesity. She has taken a sharp mental decline as she ages and often doesn't know what time of day it is, who people are, and asks questions about made up scenarios or things that she sees.
She sleeps all the time. She eats three meals a day and when she isn't eating, she is sleeping. She goes to sleep around 8:30 and wakes up around 8:30 (12 hours). Then eats the breakfast we've prepared for her and goes back to sleep for another three hours until lunchtime. After lunchtime she sleeps for another four hours until we have a caregiver come to cook her dinner and clean the apartment. After dinnertime, she dozes off until it is time for us to put her to bed again.
My question is: is this normal? Today, she could barely move from the couch to the bed (~30 feet away) and I needed to push her in a wheelchair across our hall. She is basically deadweight whenever she tries to walk or do anything and keeps saying that she is so exhausted. Is this normal for people in her condition? Or is this a bad sign of something else?
