My Mum is 84 and caring for my Dad who is 89 and has mid stage Alzheimer's.I live 100 miles away, my brother died age 56, so there is now only me. I visited today and my Mum's health is clearly suffering. She is losing weight and looks exhausted. I have begged her to let me organise some help with housework etc. or someone to sit with my Dad for a while so she has a break, but she won't hear of it.Mum is determined to manage. Some friends and family there have offered help but she has refused all of their offers. I am worried sick about them,but feel helpless because Mum won't accept help. I asked her to register as a carer with her GP but she won't even do that. Has anyone else been in this situation who can advise me please?I did say would she go to the GP for a check-up, but no was the answer.
