Bringing Assisted Living at Home

I have a grandmother who lives at home by herself. Her husband, my grandfather has been in a separate home for about 1 year now.  He is so bad off that he needs just about 24 hour care.  However, my grandmother, up until now, has been fine.  But we are now thinking about bringing in assisted living at home. This will give her some help around the home each day and someone to give her the medicine that she needs to take on a daily basis.  Otherwise she has been known to take too much medication and forget other things.
