Wow. I appreciate all the comments, which are very helpful. Here in the US, it is almost impossible to get a PET Scan. I can't figure out why, but the medical powers seem to prefer extensive neuro testing and clinic exams, blood tests, CT Scan and such. Oh, having early dementia sucks, period. I retired a few years ago due to another health issue, which has since stabilized, but I could not have worked anymore by about the same time due to my cognitive issues, which I thought at the time were related to my heart failure. Heart failure has been stable for several years, but the cognitive decline has reached alarming levels, so I finally got a complete work-up, which produced my diagnosis, which didn't really come as a surprise. My mother had early onset too. To satisfy me, I'm having a duplicate work-up at a major medical center about two hours away that has a specialized memory assessment department. My behavior, speech, anger, anxiety, confusion are bothering me much more than memory right now, although memory is really bad too. Driving isn't too good either, and it looks like that will be coming to an end sooner than I would like. I'm not overly worried, so long as I can prepare and do what I need to do to get things in order. Worrying didn't help with my heart issues, so I try not to worry. But I am very fearful, which is about the same. I'll be back here, as this board is much better than the US board. I found the UK board for cardiomyopathy was better here than in the US too. Oh, my nephew has live in the London for about 30 years now, and I doubt he will ever come back here to live. Good luck to us all.
