My mother is 87 & has dementia/Alzheimer s. She has had it for a few years now. She was always a sweet, loving, never said a bad word or a negative action. Now she can at times be very cynical, swear, cant remember things, difficult to get her to go anywhere or do anything. She is 5 ft 5, 125 lbs or so. She doesn t want to eat, afraid of getting fat like her sister. She will eat breakfast egg & cheese sandwich and a boost. picks at her supper. rarely eats lunch. She has terrible dreams and uses her fists to hit the bed at night and talks. I know this because I stayed w/my mom while my dad was in the hospital a couple of times. what medication if any will help her get her apatite back and help w/confusion. She is weak and uses a walker sometimes. Thank you very much!
