My grandad clearly has some form of dementia which I believe is Alzheimer's as it runs in our family and his brother has it. I feel like he is getting worse yet every time I tell my family he needs help nothing is done. Some agree but aren't willing to take him to the GP; others just say that he's happy etc so we should leave him alone. The problem is my family don't realise that it's a progressive disease and it can get worse, all they seem to understand is that it's not curable and therefore they see no point in treatment. I feel as though no body is listening to be because I am 18 and they believe I do not understand anything about the disease, dispute the fact that I have actually studied it and am planning to study psychology at university. I have researched this disease yet no one will listen to me and I don't know what to do. I don't want my grandad to die from this- they believe this wont happen but i keep telling them it will. I need advice!
