Hello, I was wondering if anyone could answer a few questions. (I'm new to this and don't really know how this works, so sorry if I'm doing it wrong). I'm 16 years old and my grandfather has dementia. I don't know how far along he is but it's gotten so bad that sometimes he doesn't know who I am and he comes up with scenarios in his head that are completely bizarre. He's currently staying with me and my family (mum dad and 9 year old brother) because my grandmother is finding it difficult to look after him. I'm extremely close to my grandfather, but everytime I talk to him I just want to cry because he doesn't know who I am, or even if he does I can't have normal conversations with him anymore. Sometimes I don't know what to do or say, do I correct him when he says my mother lives in nothern Ireland? Or do I just let him believe that even though she's in the same house as him? What can I do to help? What do I do or say? I feel useless and selfish when he's the one with demntia and I'm sat here healthy and fit. Please help
