My dad 82yrs isn't a well man. He had prostrate cancer 10 years ago and although in remission with that the treatment gave him leukaemia. He know has a rare form of anaemia and was told on a scale of mild to bad it is very bad. Last August (2014) he was rushed to A+E having woken up confused. By the time he got to hospital he was very confused and had lost 15 years. He was surprised at how quickly I had visited him as he'd forgotten he's been living in the same town as me for 13 years. He asked me who had brought me to hospital and not thinking I said Sam, my son, his grandson (25yrs) and he became very distressed saying Sam can't drive a car he's only 10yrs and still at school. He got quite verbally aggressive. After two days in hospital he returned home. A lot of his memory eventually came back although he's not very good at remembering family names or which day of the week it is. He doesn't remember anything about being in hospital. Four weeks ago I received another frantic phone call from my mum to say he was going to A+E again as he had passed out and was fitting. He doesn't remember that either which is perhaps a good thing for him. After brain scans and a visit to the memory clinic he's been diagnosed this week with mixed dementia. I don't know what to expect does someone with mixed dementia have more problems than someone with Alzheimer's or is it an unknown quantity?
