I was wondering if it's true that when a person is in end stage dementia no matter how much they eat they won't gain weight. I was told by a friend about 8-9 months ago when her mother-in-law passed that she kept losing weight even through she was eating because her organs weren't working correctly anymore. My mother is down to 85 lbs. but still eats two meals a day and some small snacks. Is this true?
