My Grandfather is 84 and has just been diagnosed with Alzheimers. He is awaiting an appointment with the consultant to discuss any medication he may be able to take. Unfortunately at the moment, he is losing a lot of weight despite eating really well. Is this normal? His partner makes sure he eats regularly but is worried that his weight loss is still continuing. Can anyone tell me if this is common and how we can help him? Thank you, I am so worried I don't know where else to turn.
