My mother is having issues, and refusing medical attention. Her Carotid artery is 95% blocked on one side and 100% blocked on the other. She is refusing surgery. I am hoping for a timeline, if this goes untreated. She is having little strokes, and I am not sure if I need to start looking at assisted living or preparing myself for a death - what do you think? How long can you live with blockages like this? Age - 63, heavy smoker, heart attack 6 years ago, 6 stints (heart, groin)
