My husband's 85 year-old father was diagnosed with Alzheimer's several years ago. He and my mother-in-law are in assisted living (she has cognitive impairment due to a stroke) but recently he has gone to the nurses crying that he wants to go see his parents and siblings (all are deceased). When he does this the nurses call my husband, who feels the responsibility to handle (read solve) every situation related to his parents. He is the eldest of three sons and is retired (the others are not). How can we help his father with this emotion, and therefore ourselves?
