He stopped falling and is gaining weight, but his memory won't get better. I called the nursing home about once a week to see how he has been for the past week or so, and the nurses always say that he is doing very well. However anytime I visit or call he asks to be taken home because he thinks he's at the dentist, doctors, hotel, or sometimes even in Vietnam. The nurses don't mention this when I call they just say that he's confused like usual. Is it likely that phone calls from me or his wife agitate him?
