She has moderate dementia, will be 96 in a month. She has what drs call chronic bursitis and is in a lot of pain that we cannot calm. She is spending more time in the wheelchair because of the pain also. She barely eats so I try to find things that are high calorie in a small amount of food. What I worry about is she constantly wants to sleep up to 17 hours a day. Is this common with age? Dementia? Pain? We give her as much over the counter pain meds as is safe. We are at a loss right now as to whether to try to keep her up or just let her sleep.
