My dad is 79, has dementia and broke his hip 3 1/2 weeks ago. Dad has always had a great appetite. Now hes not eating or drinking much. Sleeps all the time. Hes very disoriented. Stares at the light and says it's cloudy out. He doesn't remember me at times. I'm concerned as he's eating very little, very little fluids and is incontinent now. Dad started going downhill before he broke his hip but I'm scared as I don't know to expect from one day to the next it's something new every day. His brother died a wk ago of dementia and was 72. His vitals were good up until he passed. Too me dads has been low. 77 over 44 and the nursing home and hospital said that's a normal range for him. He does have congestive heart failure too. I'm so concerned for my dad. Any advice please...thank you!
