My FIL (who has been diagnosed with Alzheimer's) lives at home and my MIL is his primary caregiver. He behaves terribly around her. Frequently, he will not eat or get out of bed. He gets "lost" in the house, talks nonsense, has delusions, etc. All the typical signs of Alzheimer's. But when other people are around, he behaves much better. He will get out of bed, get dressed, eat a good meal, make sense most of the time when he talks. He recognizes people he sees frequently but does not remember people he has not seen for awhile. He is checked on and receives visitors several times a week by relatives and home health professionals. My MIL calls my husband several times a day to report bad behavior. She does leave the house for several hours, twice a week, so she can keep her sanity. She is ready to place him in a memory care facility. I am afraid he is to coherent for such a drastic move. Does anyone else have a loved one that behaves differently around the primary caregiver than other people? Is it possible her attitude has a negative affect on his behavior?
