Both have been used to describe my husband's illness. Can I tell the difference by the way he acts? Is it possible that he could live at home again? I am 73 years old and would need some kind of help since I'm not in the best of health. Having him at home with me and getting enough help with a caregiver would be my desire. I don't want to leave our home. I go to see him every day so I can spend time with him and help him eat dinner. Anyway this would be possible?
