Hi, I am revisiting this site after being away for about a year...too busy dealing with mom. My mom has had dementia for over 7 years. I cared for her at home until November last year when it became too difficult. My question is how long can some one live with out eating and taking in only small amounts of liquid (about 800cc/day) by eye dropper. She does not move or open her eyes or respond much to external stimuli unless she is annoyed that we are trying to feed her. She does swallow liquid from the eye dropper though. Her blood pressure, heart rate etc. are all good. Can some one exist in this state for a long period of time?
