My mother, 88, is in nursing home - parkinsons for 15 years, dementia for maybe 7 or 8 years and numerous strokes., . Whenever I visit she's asleep in her bed. She says she's so tired because she's awake all night. She's deteriorated terribly the last few weeks, mostly in bed, sometimes her wheelchair, barely able to speak, fantasizing and nastier than ever. Is this just normal as she deteriorates?
