Dad is in the late stage dementia. Today the nursing home have phoned me to say he has refused all fluids today and my sister is rushing to the home as I write. He hasn't eaten any solid food for over 3 weeks as he has now developed dysphagia but he had previously been taking fluids before today. The GP was phoned but all he has said is keep an eye on him. How long can this go on? I don't know what to do! I live 200 miles away and feel so helpless.
