Hi Theresa
Im not sure that you can become an advocate for a family member? Basically an advocate is someone who speaks on behalf of another and usually is independant.
With respect, and I am speaking independantly and from personal experience, obviously we only want what is in the best interest for the person for whom we care, but when our own ... feelings, ideas, recomendations are questioned by another person who thinks that they too have the dementia sufferers best interests at heart, who is to say that if we were to advocate for our loved one, we may not be truley representing what the dementia sufferer wants. Does that make sense? Im welsh you know!
I have tried to be my Mothers advocate unsuccessfully for this very reason, although I have not looked into the legalities of it.
I will try to get some further info for us.
