My mom is 94 and has had dementia for at least 14 years. She is in a memory care facility for 2 years now. She usually knows family when visiting is someone she knows but places us in the correct context very rarely. She can't walk but is able to wheel herself around with her feet which are often moving even if the brakes are on so she can't move. Recently she has been losing weight and showing little interest in food. She has lost 9 pounds in last 6 weeks and is now only 86 pounds. However there are times she eats fairly well. They are trying protein drinks which she will drink some times. She does still like sweet treats and takes fluid. Is this the natural wining down end of life behavior? How long can she can we expect her to go on like this.
