Mum was diagnosed with dementia 7yrs ago. We managed to keep her at home for 5ys but poor health and a heart attack left her totally bed ridden 2ys ago. After this attack and the dramatic weight loss that followed Mums weight had remained stable. The home that Mum is in could not be a more caring place, filled with wonderful staff but despite this she has started to loose weight again. The staff weigh her every week and have told me she has now dipped below 6 stone. Is this usual?
