My Mom is in the last stage of dementia and has started with mutiple organ failure. She has great difficulty swallowing and most of the time it is liquids that she takes. Mom also has a severe case of COPD. How long does she have to live? I should inform you that she is 87 years ols, has been bed-ridden for 3 years now, her muscles and brain have atrophied. She cannot turn over in the bed nor move her legs. She is down to very limited speech. Usually one word answers and sleeping about 18-20 hours a day.
