My grandmother is 93 years old, blind, diagnosed with dementia about 10 years ago but still pretty lucid. Five months ago we had to place her in a nursing home. All was well until about 3 weeks ago. She has become bedridden, on diapers full time, is in a deep sleep most of the time unless we wake her up so she can be spoon fed. Even putting her dentures on has become the most difficult task....she appears to fall asleep while trying to put in her dentures. I do not know what to make of the situation. Is this the dementia, old age or is she dying?
