Mum always struggled with her weight but now she is 90 years old, with Alzheimers and in a NH. She has lost a huge amount of weight and is down to 90lbs. She is starving herself and eating less than a bird but says she eats as much as she wants and what she enjoys. Her body image does not match reality and both staff and family are really worried. She is on various meds already for ALZ and depression. We are at a loss as to how to treat what seems like anorexia given her mental state and age.
